CSS border doesn't work with DIVs

Question

Its easy to see. In example 1 all works pretty well, but when I add one line of code more in example 2), it's breaking. Why? And how I should code it?

Example 1: http://jsfiddle.net/sUtvd/154/

[...].tripple {
width: 90%;
margin: 5%;
}[...]

Example 2: http://jsfiddle.net/Ec95D/3/

[...].tripple {
width: 90%;
margin: 5%;
border: solid;
}[...]

But, wait why in second example your dont have any border value? It is about border.. Or maybe I'm missing something — Szymon, Nov 06 '13 at 16:05

Add float:left to .tripple if border should go all way around divs

You need to clear the floats. When all of the child elements are floating, the parent is not aware of their height, and so collapses. Putting something like a clearfix on the parent should fix the problem. See http://nicolasgallagher.com/micro-clearfix-hack/ for details on the clearfix.

See http://jsfiddle.net/designingsean/Ec95D/4/ for a working example. CSS from the link is below. Then just add .cf to the parent element.

.cf:before,
.cf:after {
  content: " ";
  display: table;
} 

.cf:after {
  clear: both;
}

You could also make the parent have an overflow set to pretty much anything, though auto makes the most sense in most cases. See http://jsfiddle.net/designingsean/cx7Wg/ for a working example of that.

For more on clearfix vs overflow, check out this pretty solid SO question and answer: What methods of ‘clearfix’ can I use?

You should clear your floats: you can use this standard css from HTML5 biolerplate:

.clearfix:before,
.clearfix:after {
    content: " ";
    display: table;
}

.clearfix:after {
    clear: both;
}

Fiddle

<div class="tripple clearfix">

I personally use a div which is to clear:both for these occasions. Check this fiddle.

The float property in:

.left, .right, .middle {
    float:left;
    width: 33%;
    height: 100px;
}

makes the parent div empty. Float is a CSS positioning property.

There could be a better approach, but a simple way is to put each colored box in a table with 0 cell spacing and padding.
