Vertically Center Text in an Input Element

I have the following input element (I deliberately omitted attributes which weren't necessary for the example):

<input type="text" style="display: block; height: 40px; font-size: 14px; line-height: 40px"/>

In Chrome and Internet Explorer (probably Opera too), any text inside the input will be vertically centred. However, Firefox seems to ignore this declaration. Setting it to display: inline-block; instead, or using vertical-align: middle; has no effect in Firefox.

I've also tried settin开发者_JS百科g the top & bottom paddings to 13px, and the height to 14px, which (combined with the font-size) will result in an element 40px tall. This works as expected; except any characters with tails (like g, q, j etc) are cut off at the bottom.

I'm looking for a cross-browser solution for vertically aligning text in an input box with a fixed height. The input element will have its own hover and focus styles, so faking the centring by positioning the element itself vertically in a 40px tall space is not really an option.

Cheers

How about setting only the top padding to 13px (not the bottom one) and setting the height to the remaining space, like this:

<input type="text" style="display: block; height: 27px; padding-top: 13px; font-size: 14px">

It works as expected in both Firefox and Chrome; I haven't access to IE at the moment, but I'm quite confident it works in IE too.
