The position of the text on the search submit button on my blog is very low in Firefox 4, but not Chrome 10 or IE9. I\'ve tried almost everything, and nothing works except l

    I had been facing a similar problem when using CSS inside buttons. The text was offset by 1 pixel in firefox, and rest of the browsers it was just fine. I used "padding" property specific to Firefox, in the following way

    The original code in which the input button's text was one pixel lower in Firefox

    .mybutton { 
    height:32px; background-color:green; 
    font-size:14px; color:white; font-weight:bold; 
    border:0px; -moz-border-radius:16px; border-radius:16px;
}

    and after adding the Firefox specific padding after the above css, it was perfect in Firefox

    @-moz-document url-prefix() {
    .mybutton { padding-bottom:1px; }
}

    In your case, may be you need a bit more padding-bottom, and probably padding-top in negative too (-1px or -2px).

    lots of anwsers here... i think this is the simplest way to do this :

    .searchform input[type="submit"]
{
    height: 35px;
    line-height: 35px;
    font-size: 2em;
}

    Hope this helps =D

    I have found that a combination of padding and line-height does the trick. As stated Firefox ignores line-height.

    1. Make sure you set a larger bottom padding than top padding. Fiddle around with it a bit and you will be able to vertically align the text in Firefox.
    2. You will then see that this pushes the text too close to the top of the element in Webkit. Now use a large line-height to align it properly in Webkit and voila!

    I have tested this on a Windows 7 machine running Firefox 7, Chrome 16, Safari 5.1 and IE9.

    I've deduced that the main trouble is the line-height property.

    Both browsers attempt to vertically center all text on buttons. In combination with the height property, however, if there is not enough room to render the full standard line-height (glyph padding grows quite large with large font sizes), both browsers will pin the glyph to the top of the button, trimming the bottom.

    Normally, the line-height would help adjust this, and in Chrome, in your example, this was successful. However, in the case of button and input type="submit" elements, Firefox ignores line-height altogether, so it can't be used in this way to "fix" the positioning of the character. Using the extreme example below, we can see that the text has been pushed out of visbility in Chrome, while it still stays right in the (vertical) center in Firefox.

    <!doctype html>

<html>
<body>
<style type="text/css">
input {
    border:1px solid black; 
    line-height:1000px;
    height:40px;
}
</style>
<input type="submit" value="Test"/>
</body>
</html>

    Firefox: Firefox Chrome: Chrome

    When a button element is left to the native style (remove the border), line-height is ignored by both browsers (weirdly, Chrome also ignores the height but Firefox does not). As soon as the button is custom-styled, Chrome picks up the line-height but Firefox does not.

    So what can you do?

    If you still want to make use of CSS fonts...

    1. First of all, make sure your font renders the glyphs in the same vertical-alignment that a standard font displays a basic full-height character, like H. (It appears you've done this for the most part, since your page looks significantly better than the screenshots in the question.)
    2. Second, you'll notice that if you use a font like Arial, and display an H (at the same font size), it's also low. This is because the built in standard line-height of the font gives it quite a bit of room above the character. This indicates that you may have some success if you can edit the font to trim this, thereby giving the character enough room to not be trimmed at the bottom by the browser.
    3. Probably less ideal to you, but still an option, you can use other elements, either in combination with or in place of the button/submit element, to get the character into place.

    Alternative option

    I'm not sure what your goal is in using CSS fonts, but often it is for some form of progressive enhancement/graceful degradation. In this case, although (as you said in the comments) the special character is a standardized Unicode "right-pointing magnifying glass", it still will not have any meaning to the user if it doesn't render.

    Given that the benefit of graceful degradation is to allow simpler technologies to display your website without appearing broken, the use of this character seems suspect — without CSS fonts or a native font with this character, it will render as 🔍 a ?, or simply a blank box.

    A better option for graceful degradation, given this problem, would be to simply use a background-image. Make the text of the button "Search", hide the text (through CSS), and apply the background image, and then you have actual graceful degradation, and a fancy character for better browsers.

    A background image could also (obviously dependent on the files themselves) have other benefits, such as faster load and render times (for instance, if a developer wanted to use a single character from a full-character-set font).

    I came across this when I was looking for a solution to this problem, but since I never really found anything other than a hint at changing the padding bottom I wanted to share that I found adjusting the padding-bottom for just firefox worked great.

    Every other browser allowed for enough line-height control to adjust the text positioning.

    /* This gets picked up in firefox only to adjust the text into the middle */
@-moz-document url-prefix() {
    input[type="button"],
    input[type="submit"],
    button.btn {
        padding-bottom: 6px;
    }
}
