Question

I have an icon that I would like to be able to drop into text at arbitrary points and have it “flow” with the text.

Background:

An <img> tag works best for this. However, I don’t want to have to specify the href everywhere. That will present problems in the future should the icon/location change. It also depends on me knowing the path to the image which I won’t always know due to URL-rewrites and different mappings to the same page, etc. I would like to do something like <span class="icon"></span> and have my icon as the background-image. Of course, this doesn’t work since you can’t have width on an inline element. Having it as a block (ie. <div>) element doesn’t work (for obvious reasons) and floating it doesn’t work either. display: inline-block; works in some browsers but not all. Using padding: to pad-out the correct height and width gives mixed results in different browsers. Using an <img> tag with a transparent image for the href and a background-image
works but seems hacky.

Any thoughts on what the best way to accomplish this would be?

Answer 1

You could make the <span class="icon"></span> absolutely positioned within your link like so:

<a href="">Some text <span class="icon"></span></a>

You can specify width/height on absolutely positioned elements, so the CSS would look something like this:

a {
    position: relative;
    padding-right: 30px; /* width of your icon, assuming you're placing to the right of the text */
}

a .icon {
    display: block; /* for good measure, but won't be required in all browsers */
    position: absolute;
    top: 0;
    right: 0;

    width: 30px;
    height: 30px;

    background: url(your-icon.png) no-repeat 0 0;
}

By setting the <a>‘s postion to relative, it makes it the coordinate system for the absolutely positioned <span class="icon">.

Using an Image Tag for the Icon

If you don’t know where the icon will appear, you can use an <img> tag with a transparent .gif as its source.

<p>Lorem ipsum <img src="clear.gif" alt="icon" class="icon" /> dolar velarium</p>

Then set the real icon source using the CSS background property:

img.icon {
    height: 30px;
    width: 30px;
    background: url(true-icon-src.png) no-repeat 0 0;

    /* Use the following if you want to adjust the image's vertical position */
    position: relative;
    top: 5px;
}
