I have a problem of div width. first div width is 100%. now into this div there are two div one is 60% width and float is left and if I set another div with 40% width and float: left then it comes on the lower side of the first div. but if I set the width 39.60% then it is on left side. my question is how can I set the percentage in whole number so that two div is remain side by side?

What I have tried:

HTML

<div style="float: left; width: 100%;height: 40%; border: solid 1px yellow;">
            <div style="float: left; width: 60%; height: 100%; border: solid 1px red;">
            </div>
            <div style="float: left; width: 39.60%; height: 100%; border: solid 1px red;">
            </div>
        </div>

This is due to the default box-sizing[^], which is content-box. The width you specify excludes the padding, margin and border. Your two boxes have 1px borders on either side, so their total width is 100% + 4px.

If you change the box-sizing to border-box, the width includes the padding and border, so your boxes will fit on one line.

CSS

*, :before, :after 
{
    box-sizing: border-box;
}
