Getting 100% height on floated neighboring divs: Tips and tricks

Question

Getting 100% height on floated neighboring divs: Tips and tricks

<div id='container'>
    <div class='left'></div>
    <div class='right'></div>
    <div class='clear'></div>
</div>

If you encounter the scenario above where the floated right div needs to occupy the remaining height of its parent container without an explicit height being set, how would you tackle this challenge? The height of the parent container is dictated by the floated left div.

My usual approach involves utilizing Javascript post-loading to adjust heights accordingly. However, I am curious about alternative, standard, and more efficient methodologies for managing this particular layout quirk.

It appears that structuring a layout in this manner inherently raises complications. Are there feasible solutions beyond resorting to using a <table>?

Answer №1

If you want to achieve this layout without specifying a height on the parent using floats, you can utilize display: table; and table-cell properties to simulate table behavior:

#container { 
    width: 200px;
    background-color: green;
    display: table;
}
.left {
    display: table-cell;
    width: 30px;
    height: 200px;
    background-color: red;
}
.right {
    display: table-cell;
    height: 100%;
    width: 30px;
    background-color: blue;
}

This method eliminates the need for a clearing element and ensures that both divs always occupy 100% of the height when specified.
