Answer 1

I was able to get it working by adding padding-bottom to the fieldset for Chrome only. This balances out some of the extra height %. It's nice in that it works (relatively consistently) even when resizing.

if (navigator.userAgent.toLowerCase().indexOf('chrome')) { // Replace this with your preferred way of checking userAgent
    $('fieldset').css('padding-bottom', '4%'); // Exact percent may vary
}

Just as a note, I found this to be an issue in at least IE8 - IE11 as well, so the fix can be applied to IE.

Answer 2

The answer was kinda weird, but I make it work, looks like the margin was making a mess here, if I set it to margin: 0 5px; then I can make both fieldsets to have the same height as their parent

Part of the css markup:

fieldset
{
    border: 1px solid #ffffd;
    padding: 0 1.4em 1.4em 1.4em;
    margin: 0 0 1.5em 0;
    border-radius: 8px;
    margin: 0 5px;
    height: 100%;
}

legend
{
    font-size: 1.2em;
    font-weight: bold;
}
.blahContainer{
    width: 100%;
    height: 100%;
}

.blahColumna1{
    width: 70%;
    height: 100%;
}

Answer 3

Try wrapping both <fieldset>s in a single container <div> that isn't fixed height -- it will neatly enclose blah2, and will grow up to the max size of your <div> parent. Set blah1's height to be 100% of the containing <div>.
