Wrong vertical align of text in Google Chrome browser

Question

I have problem with creating "button" element (text in inline-block container with border), because in some font-size text has wrong vertical-align (is not perfect middle).

I want to use Raleway (Google Web Font) and Bootstrap. Height of the text container is set by line-height.

I am testing it on Windows 7...

on Firefox (ver. 36) everything is perfect

but the problem is on Google Chrome (ver. 41)

Part of CSS code:

/*Bootstrap default style*/
* {
    box-sizing: border-box;
}
.btn {
    display: inline-block;
    vertical-align: middle;
}

/*custom style*/
body {
    font-family: "Raleway";
}
.btn {
    padding-top: 0;
    padding-bottom: 0;
    line-height: 16px;
    font-size: 11px; /*real height: 8*/
}
.btn-sm {
    font-size: 10px; /*real height: 7*/
    line-height: 15px;
 }
.btn-lg {
    font-size: 12px; /*real height: 8-9*/
    line-height: 16px; /*light, normal*/
 }

As you can see in Chrome preview in some font-size and font-weight text is go up relative container.

3x zoom sample, with font-size: 11px (line-height: 16px) and font-weight: semi-bold.

Top and bottom space (between text and top/bottom border) should be the same: 4px, but as you can see top space has 3px and bottom has 5px.

Is it possible to fix this browser issue?

Answer 1

This very annoying problem is caused by chrome not taking text-transform: uppercase into account. Use the following to get correct centering in Chrome with all-caps text:

text-transform: lowercase;
font-variant: small-caps;

Works great for buttons, for other usecases you might have problems with the text being small-caps and not real caps.
