Firefox line-height issue with input fields

Question

I have realized the problem before but I guess it didn't matter as much then as it did now.

What I discovered is that Firefox has a default line-height value of 1.2 for input fields which can not be changed. At least in OSX, don't have Windows so I can't confirm it there.

I did some experimenting and testing and there's just no way to change the default line-height value of Firefox. All the other browsers (ok, I just tried with Chrome and Safari) obey my value perfectly fine but not Firefox.

Has anyone ever noticed this and if yes, have you found a solution to overcome this?

Answer 1

Unfortunatelly the line-height is set to !important in the Firefox base css ... http://hg.mozilla.org/mozilla-central/rev/b97aef275b5e

Answer 2

I always style my buttons against anchors, buttons, labels, and submits to ensure that regardless of which element used, the outcome looks exactly the same.

Since Firefox insists on using !important to declare line-height, the only way I can calmly overcome this issue is to force all other vendors to use line-height: normal for buttons, and then use padding to vertically center the text:

 /**  * Consistently style buttons on anchors, buttons, labels, and submits  */ .btn {     .     .     .     height: auto;        // ensure heights on inputs do not affect submit buttons     line-height: normal; // all browsers use FF's ever unchanging value     padding: .5em 1em;   // vertically center the text in the button     .     .     . } 

This works similarly for inputs.
