Table cells height calculated differenly in IE11

css, css-tables, internet-explorer, internet-explorer-11

Solution

I finally managed to do that. Here is the code, hope it helps. Fiddle here.

var spans = document.querySelectorAll( "span.bar" ),
count = spans.length;
while ( count-- ) {
   spans[count].style.height = spans[count].parentElement.offsetHeight + "px";
}
    

body {
    padding:15px;
}
table {
    border: 1px solid black;
    border-spacing: 10px;
    cell-spacing: 0;    
}

tr {
    border: 1px solid red;
}

td {
    vertical-align:center;
    position:relative;
    box-sizing: border-box;
    position: relative;
    border: 1px solid black;
}

td .bar:first-child,
td .bar:last-child {
    display: block;
    background: green;
    width: 3px; 
    left: -5px;
    height: 100%;
    position: absolute; top: 0; 
    z-index: 1;
}

p {
    margin: 0;
    background-color: #dedede;
    padding: 0px;
}

.tall {
    height: 100px;
}

.medium {
    height: 60px;
}

.short {
    height: 30px;
}

<table cellspacing="1" cellpadding "0" border="0">
    <tr>
        <td>
            <span class="bar"></span><p class="tall">Save me!</p><span class="bar"></span>
        </td>
        <td>
            <span class="bar"></span><p class="medium">From problems</p><span class="bar"></span>
        </td>
        <td>
            <span class="bar"></span><p class="short">With IE</p><span class="bar"></span>
        </td>
    </tr>
</table>

Problem

The problem I face is IE 11 seem to have inconsistent `<td>` inner height across single `<tr>` while other browsers keep it the same. Here's a pen illustrating my problem: http://codepen.io/anon/pen/emKEBZ In my layout I have an absolutely positioned pseudo-element (green border) which I want to display on a (outside) `<td>`. I'd like it to be always as high as the whole `<tr>` it is in. The content of `<td>`s is dynamic - I have no control over it's size (like I do in the pen). I gave it `height: 100%`, assuming that every `<td>` in a row has the same height. ``` td { position: relative; } td:before { content: ""; display: block; position: absolute; top: 0; left: -5px; width: 3px; height: 100%; background-color: green; } ``` And yeah, that height calculates to the same value across all of the cells in the same row in Firefox and Chrome: but to different height for each cell in IE 11: The problem seems to be that in `height: 100%` IE refers to the inner height (the one inside the padding) of the containing `<td>`, while other browsers take total height (height + padding + border). And even then, the inner height of all `<td>`s along one `<tr>` is identical in Firefox, while it isn't in IE. Is any of those approaches wrong? Is there a way to force IE to work like other browsers do?
