As many as 60 percent of the Kenyan population now has access to electricity according to official data. But in neighbouring Tanzania, the penetration rate is less than half of that and sparsely populated rural communities are especially neglected.  

The post Tanzania turns to solar power to increase electricity connectivity appeared first on LatestSolarNews.

So let’s say we have a “bar” with some items inside. Like a header or footer. Let’s also say we want those items to be spaced evenly, meaning they have the same gap everywhere. Shouldn’t be a big problem. Let’s take a look:

1. Margin

We can’t just add margin: 2rem to the elements since there is no margin collapsing on the horizontal axis. And it also doesn’t work when using Flexbox. Leaving a double sized gap in between. Wishing there is something like margin: 2rem collapse; where you can enable/disable it optionally.

See the Pen Spacing elements (no collapsing) by simurai (@simurai) on CodePen.

2. Pseudo classes

Using margin: 2rem 0 2rem 2rem and then a pseudo class like :last-child { margin-right: 2rem } to add the extra margin works as long as you don’t need to hide that element with display: none. Maybe a rare case, but I’ve been running into this issue once in a while. Would be cool if there is something like :last-displayed that would ignore elements that have display:none.

3. Margin + padding (best)

The easiest way I think, is to add margins to all elements (like in the first example), but then also add the same value as padding to the parent element. Like this:

.Header {
  padding: 1rem;
}
.Header-item {
  margin: 1rem;
}

That way all elements are evenly spaced and you still can use display:none without having to worry about breaking it. A little flaw is that you have to keep the 2 values in sync, but if you’re using a preprocessor, it can just be a single variable. Or maybe you could use REM’s to control it with font-size from the :root.

Other?

There are more ways but I’m not aware of a simple one that also let’s you use display: none. Let me know otherwise.

• Maybe the Visual Format Language in GSS? Looks quite slick.

Update

A couple more options:

• Using Grandpa’s table, still need to test this
• Using calc()
• Using Adjacent selector
• More selector “hacks”: 1, 2

Hmmm.. gotta try some. I kinda like the 3rd one. Keeps it independent from the parent and is not “too” complicated.
