as Wasp nest By nicolasgallagher.com Published On :: Thu, 26 Nov 2009 16:00:00 -0800 Most people I know hate and fear wasps. I’ve always been intrigued by them; they are quite beautiful looking insects – social insects – that have an important role in ecosystems. Their nests are incredible and I found and photographed a large nest constructed this year in our roof cavity. This nest is about the diameter of a football (soccer ball) and gives you an idea of the intricate structure of a wasp nest made up of thousands of thin fans of paper-like material. Unlike honey bees, wasps do not have wax-producing glands and those that make these kinds of nests construct them from a substance derived from wood pulp. They usually chew on dead or weathered wood and you can sometimes find wasps stripping thin layers from man-made wooden objects like park benches, panelling on houses, or exposed window frames. Wasps mix this wood with saliva to produce a paper-like material that is used to construct their nest. You can see how each fanned layer of paper is made up of bands of different colour. This is presumably because the layers been progressively built up by wasps returning with wood pulp sourced from different types and colours of wood. The final effect is really beautiful and it’s impressive to think that this kind of large organised structure, which houses the queen’s larvae in combs and regulates temperature, is the result of thousands of individual wasps working together. It is only used for one season before being abandoned as the winter approaches and the majority of the colony dies from cold. Full Article
as Better conditional classnames for hack-free CSS By nicolasgallagher.com Published On :: Thu, 19 May 2011 17:00:00 -0700 Applying conditional classnames to the html element is a popular way to help target specific versions of IE with CSS fixes. It was first described by Paul Irish and is a feature of the HTML5 Boilerplate. Despite all its benefits, there are still a couple of niggling issues. Here are some hacky variants that side-step those issues. An article by Paul Irish, Conditional stylesheets vs CSS hacks? Answer: Neither!, first proposed that conditional comments be used on the opening html tag to help target legacy versions of IE with CSS fixes. Since its inclusion in the HTML5 Boilerplate project, contributors have further refined the technique. However, there are still some niggling issues with the “classic” conditional comments approach, which Mathias Bynens summarized in a recent article on safe CSS hacks. The Compatibility View icon is displayed in IE8 and IE9 if you are not setting the X-UA-Compatible header in a server config. The character encoding declaration might not be fully contained within the first 1024 bytes of the HTML document if you need to include several attributes on each version of the opening html tag (e.g. Facebook xmlns junk). You can read more about the related discussions in issue #286 and issue #378 at the HTML5 Boilerplate GitHub repository. The “bubble up” conditional comments method Although not necessarily recommended, it looks like both of these issues can be avoided with a bit of trickery. You can create an uncommented opening html tag upon which any shared attributes (so no class attribute) can be set. The conditional classes are then assigned in a second html tag that appears after the <meta http-equiv="X-UA-Compatible"> tag in the document. The classes will “bubble up” to the uncommented tag. <!DOCTYPE html> <html lang="en"> <head> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <meta charset="utf-8"> <!--[if lt IE 7]><html class="no-js ie6"><![endif]--> <!--[if IE 7]><html class="no-js ie7"><![endif]--> <!--[if IE 8]><html class="no-js ie8"><![endif]--> <!--[if gt IE 8]><!--><html class="no-js"><!--<![endif]--> <title>Document</title> </head> <body> </body> </html> Fork the Gist The result is that IE8 and IE9 won’t ignore the <meta http-equiv="X-UA-Compatible"> tag, the Compatibility View icon will not be displayed, and the amount of repeated code is reduced. Obviously, including a second html tag in the head isn’t pretty or valid HTML. If you’re using a server-side config to set the X-UA-Compatible header (instead of the meta tag), then you can still benefit from the DRYer nature of using two opening html tags and it isn’t necessary to include the conditional comments in the head of the document. However, you might still want to do so if you risk not containing the character encoding declaration within the first 1024 bytes of the document. <!DOCTYPE html> <html lang="en"> <!--[if lt IE 7]><html class="no-js ie6"><![endif]--> <!--[if IE 7]><html class="no-js ie7"><![endif]--> <!--[if IE 8]><html class="no-js ie8"><![endif]--> <!--[if gt IE 8]><!--><html class="no-js"><!--<![endif]--> <head> <meta charset="utf-8"> <title>Document</title> </head> <body> </body> </html> Fork the Gist The “preemptive” conditional comments method Another method to prevent the Compatibility View icon from showing was found by Julien Wajsberg. It relies on including a conditional comment before the DOCTYPE. Doing this seems to help IE recognise the <meta http-equiv="X-UA-Compatible"> tag. This method isn’t as DRY and doesn’t have the character encoding declaration as high up in the document, but it also doesn’t use 2 opening html elements. <!--[if IE]><![endif]--> <!DOCTYPE html> <!--[if lt IE 7]><html class="no-js ie6"><![endif]--> <!--[if IE 7]><html class="no-js ie7"><![endif]--> <!--[if IE 8]><html class="no-js ie8"><![endif]--> <!--[if gt IE 8]><!--><html class="no-js"><!--<![endif]--> <head> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <meta charset="utf-8"> <title>Document</title> </head> <body> </body> </html> Fork the Gist While it’s interesting to explore these possibilities, the “classic” method is still generally the most understandable. It doesn’t create invalid HTML, doesn’t risk throwing IE into quirks mode, and you won’t have a problem with the Compatibility View icon if you use a server-side config. If you find any other approaches, or problems with those posted here, please leave a comment but also consider adding what you’ve found to the relevant issues in the HTML5 Boilerplate GitHub repository.

as “Mobile first” CSS and getting Sass to help with legacy IE By nicolasgallagher.com Published On :: Mon, 28 Nov 2011 16:00:00 -0800 Taking a “mobile first” approach to web development poses some challenges if you need to provide a “desktop” experience for legacy versions of IE. Using a CSS pre-processor like Sass can help. As of Sass 3.2, there is another way of catering for IE, described by Jake Archibald. One aspect of a “mobile first” approach to development is that your styles are usually gradually built up from a simple base. Each new “layer” of CSS adds presentational adjustments and complexity, via CSS3 Media Queries, to react to and make use of additional viewport space. However, IE 6/7/8 do not support CSS3 Media Queries. If you want to serve IE 6/7/8 something more than just the base CSS, then you need a solution that exposes the “enhancing” CSS to those browsers. Popular existing options An existing option is the use of a CSS3 Media Query polyfill, such as Respond.js. However, there are some drawbacks to this approach (see the project README), such as the introduction of a JavaScript dependency and the XHRing of your style sheets, which may introduce performance or cross-domain security issues. Furthermore, adding support for CSS3 Media Queries is probably not necessary for these legacy browsers. The main concern is exposing the “enhancing” CSS. Another method, which Jeremy Keith has described in his post on Windows mobile media queries, is to use separate CSS files: one basic global file, and an “enhancing” file that is referenced twice in the <head> of the document. The “enhancing” file is referenced once using a media attribute containing a CSS3 Media Query value. This prevents it being downloaded by browsers (such as IE 6/7/8) which do not support CSS3 Media Queries. The same file is then referenced again, this time wrapped in an IE conditional comment (without the use of a CSS3 Media Query value) to hide it from modern browsers. However, this approach becomes somewhat cumbersome, and introduces multiple HTTP requests, if you have multiple breakpoints in your responsive design. Getting Sass to help Sass 3.1 provides some features that help make this second approach more flexible. The general advantages of the Sass-based approach I’ve used are: You have full control over how your style sheets are broken up and reassembled. It removes the performance concerns of having to reference several separate style sheets for each breakpoint in the responsive design, simply to cater for IE 6/7/8. You can easily repeat large chunks of CSS in separate compiled files without introducing maintenance problems. The basic idea is to produce two versions of your compiled CSS from the same core code. One version of your CSS includes CSS3 @media queries and is downloaded by modern browsers. The other version is only downloaded by IE 6/7/8 in a desktop environment and contains no CSS3 @media queries. To do this, you take advantage of the fact that Sass can import and compile separate .scss/.sass files into a single CSS file. This allows you to keep the CSS rules used at any breakpoint completely separate from the @media query that you might want it to be a part of. This is not a CSS3 Media Query polyfill, so one assumption is that IE 6/7/8 users will predominantly be using mid-size screens and should receive styles appropriate to that environment. Therefore, in the example below, I am making a subjective judgement by including all the breakpoint styles up to a width of 960px but withholding those for any breakpoints beyond that. The ie.scss file imports numerous other files, each containing a layer of CSS that builds upon the previous each layer of CSS. No CSS3 @media queries are contained within the files or the ie.scss file. It then compiles to a single CSS file that is designed to be served only to IE 6/7/8. // ie.scss @import "base"; @import "320-up"; @import "480-up"; @import "780-up"; @import "960-up"; The style.scss file imports the code for each breakpoint involved in the design (including any beyond the limit imposed for legacy versions of IE) but nests them within the relevant CSS3 @media query. The compiled version of this file is served to all browsers apart from IE 6/7/8 and IEMobile. // style.scss @import "base"; @media (min-width:320px) { @import "320-up"; } @media (min-width:480px) { @import "480-up"; } @media (min-width:780px) { @import "780-up"; } @media (min-width:960px) { @import "960-up"; } @media (min-width:1100px) { @import "1100-up"; } The resulting CSS files can then be referenced in the HTML. It is important to hide the ie.css file from any IE-based mobile browsers. This ensures that they do not download the CSS meant for desktop versions of IE. <!--[if (gt IE 8) | (IEMobile)]><!--> <link rel="stylesheet" href="/css/style.css"> <!--<![endif]--> <!--[if (lt IE 9) & (!IEMobile)]> <link rel="stylesheet" href="/css/ie.css"> <![endif]--> This Sass-enabled approach works just as well if you need to serve a basic style sheet for mobiles without CSS3 Media Query support, and prevent those devices from downloading the CSS used to adapt the layout to wider viewports. For example, you can avoid importing base.scss into the ie.scss and style.scss files. It can then be referenced separately in the HTML. <link rel="stylesheet" href="/css/base.css"> <link rel="stylesheet" href="/css/style.css" media="(min-width:320px)"> <!--[if (lt IE 9) & (!IEMobile)]> <link rel="stylesheet" href="/css/ie.css"> <![endif]--> You’ll notice that I didn’t wrap the style.css reference in a conditional comment to hide it from legacy versions of IE. It’s not necessary this time because the value of the media attribute is not understood by legacy versions of IE, and the style sheet will not be downloaded. In different circumstances, different combinations of style sheets and media attribute values will be more appropriate. Summary Even if you want to don’t want to use any of the Sass or SCSS syntax, the pre-processor itself can help you to write your CSS in a “mobile first” manner (with multiple breakpoints), provide a “desktop” experience for IE 6/7/8, and avoid some of the performance or maintenance concerns that are sometimes present when juggling the two requirements. I’m relatively new to using Sass, so there may be even better ways to achieve the same result or even to prevent the inclusion of IE-specific CSS unless the file is being compiled into a style sheet that only IE will download.

as CSS: the cascade, specificity, and inheritance By nicolasgallagher.com Published On :: Sun, 04 Mar 2012 16:00:00 -0800 What is the cascade? The cascade is a mechanism for determining which styles should be applied to a given element, based on the rules that have cascaded down from various sources. The cascade takes importance, origin, specificity, and source order of style rules into account. It assigns a weight to each rule. When multiple rules apply to a given element, the rule with the greatest weight takes precedence. The result is an unambiguous way to determine the value of a given element/property combination. Browsers apply the following sorting logic: Find all declarations that apply to a given element/property combination, for the target media type. Sort declarations according to their importance (normal or important) and origin (author, user, or user agent). From highest to lowest precedence: user !important declarations author !important declarations author normal declarations user normal declarations user agent declarations If declarations have the same importance and source, sort them by selector specificity. Finally, if declarations have the same importance, source, and specificity, sort them by the order they are specified in the CSS. The last declaration wins. What is specificity? Specificity is a method of conflict resolution within the cascade. Specificity is calculated in a very particular way, based on the values of 4 distinct categories. For explanatory purposes, the CSS2 spec represents these categories using the letters a, b, c, and d. Each has a value of 0 by default. a is equal to 1 if the declaration comes from a style attribute in the HTML (“inline styles”) rather than a CSS rule with a selector. b is equal to the number of ID attributes in a selector. c is equal to the number of other attributes and pseudo-classes in a selector. d is equal to the number of elements and pseudo-elements in a selector. The specificity is given by concatenating all 4 resulting numbers. More specific selectors take precedence over less specific ones. For example, the selector #id .class[href] element:hover contains: 1 ID (b is 1) 1 class, 1 attribute selector, and 1 pseudo-class (c is 3) 1 element (d is 1) Therefore, it has a specificity of 0,1,3,1. Note that a selector containing a single ID (0,1,0,0) will have a higher specificity than one containing any number of other attributes or elements (e.g., 0,0,10,20). This is one of the reasons why many modern CSS architectural patterns avoid using IDs for styling purposes. What is inheritance? Inheritance is distinct from the cascade and involves the DOM tree. Inheritance is the process by which elements inherit the the values of properties from their ancestors in the DOM tree. Some properties, e.g. color, are automatically inherited by the children of the element to which they are applied. Each property defines whether it will be automatically inherited. The inherit value can be set for any property and will force a given element to inherit its parent element’s property value, even if the property is not normally inherited. About !important The above should make it apparent that !important is a separate concept to specificity. It has no effect on the specificity of a rule’s selector. An !important declaration has a greater precedence than a normal declaration (see the previously mentioned cascade sorting logic), even declarations contained in an element’s style attribute.

as Using canvas to fix SVG scaling in Internet Explorer By nicolasgallagher.com Published On :: Mon, 18 May 2015 17:00:00 -0700 Internet Explorer 9–11 suffer from various bugs that prevent proper scaling of inline SVG’s. This is particularly problematic for SVG icons with variable widths. This is the canvas-based hack I’ve been using to work around the issue. A popular way to use SVG icons is to generate a spritemap of SVG symbol‘s that you then reference from elsewhere in a document. Most articles on the topic assume your icon dimensions are uniformly square. Twitter’s SVG icons (crafted by @sofo) are variable width, to produce consistent horizontal whitespace around the vectors. Most browsers will preserve the intrinsic aspect ratio of an SVG. Ideally, I want to set a common height for all the icons (e.g., 1em), and let the browser scale the width of each icon proportionally. This also makes it easy to resize icons in particular contexts – just change the height. Unfortunately, IE 9–11 do not preserve the intrinsic aspect ratio of an inline SVG. The svg element will default to a width of 300px (the default for replaced content elements). This means it’s not easy to work with variable-width SVG icons. No amount of CSS hacking fixed the problem, so I looked elsewhere – and ended up using canvas. canvas and aspect ratios A canvas element – with height and width attributes set – will preserve its aspect ratio when one dimension is scaled. The example below sets a 3:1 aspect ratio. <canvas height="1" width="3"></canvas> You can then scale the canvas by changing either dimension in CSS. canvas { display: block; height: 2rem; } Demo: proportional scaling of canvas. Fixing SVG scaling in IE This makes canvas useful for creating aspect ratios. Since IE doesn’t preserve the intrinsic aspect ratio of SVG icons, you can use canvas as a shim. A canvas of the correct aspect ratio provides a scalable frame. The svg can then be positioned to fill the space created by this frame. The HTML is straightforward: <div class="Icon" role="img" aria-label="Twitter"> <canvas class="Icon-canvas" height="1" width="3"></canvas> <svg class="Icon-svg"> <use fill="currentcolor" xlink:href="#icon-twitter"></use> </svg> </div> So is the CSS: .Icon { display: inline-block; height: 1em; /* default icon height */ position: relative; user-select: none; } .Icon-canvas { display: block; height: 100%; visibility: hidden; } .Icon-svg { height: 100%; left: 0; position: absolute; top: 0; width: 100%; } Setting the canvas height to 100% means it will scale based on the height of the component’s root element – just as SVG’s do in non-IE browsers. Changing the height of the Icon element scales the inner SVG icon while preserving its 3:1 aspect ratio. Demo: proportional scaling of svg in IE. Creating an Icon component The hack is best added to (and eventually removed from) an existing icon component’s implementation. If you’re generating and inlining an SVG spritemap, you will need to extract the height and width (usually from viewBox) of each of your icons during the build step. If you’re already using the gulp-svgstore plugin, it supports extracting metadata. Those dimensions need to be set on the canvas element to produce the correct aspect ratio for a given icon. Example React component (built with webpack): import iconData from './lib/icons-data.json'; import React from 'react'; import './index.css'; class Icon extends React.Component { render() { const props = this.props; const height = iconData[props.name.height]; const width = iconData[props.name.width]; // React doesn't support namespaced attributes, so we have to set the // 'use' tag with innerHTML const useTag = `<use fill="currentcolor" xlink:href="#icon-${props.name}"> </use>`; return ( <span className="Icon"> <canvas className="Icon-canvas" height={height} width={width} /> <svg className="Icon-svg" dangerouslySetInnerHTML={{__html: useTag}} key={props.name} /> </span> ); } } export default Icon; When I introduced this hack to a code base at Twitter, it had no impact on the the rest of the team or the rest of the code base – one of the many benefits of a component-based UI.
