Question

Im having trouble with a span tag showing a background image in the latest FF on windows 7.
It seems to work and show everything fine in earlier FF, Chrome, Safari and IE but handheld devices and windows 7 it seems to fail.

Sorry if this seems vague I just cant figure it out, the images were originally pngs with no height specified and ive since made them gifs and applied a height.

<span class="design">Design Viz</span>
<style>
.design  {
    background:url(_includes/images/agenda-design.gif) no-repeat top left;
    display: inline-block;
    height: 17px;
    padding-left:25px;
}
</style>

Answer 1

The background-image CSS property only puts an image as the background. The width and height of an object is always defined either by static settings via CSS/inline styling, or by the actual size of the content displayed in it.
In your case, since you haven’t added any content between your tags, its x/y dimensions will be 0, but there is no bug with the background. It’s there, only you can’t see it unless you define (somehow) a size for the element.

<span class="design">Design Viz</span>
.design  {
padding-left:25px;
background:url(_includes/images/agenda-design.gif) no-repeat top left;
display: inline-block;
height: 17px;
width: 50px;
}

Where 50 can be any helpful value suited for your case.
