copied!<p>OK, the first thing to note is that <del><code><i></code> has been deprecated, and shouldn't be used</del> <code><i></code> has not been deprecated, but I still do not recommend using it—see the comments for details. This is because it goes entirely against keeping presentation in the presentation layer, which you've pointed out. Similarly, <code><span class="italic"></code> seems to break the mold too.</p> <p>So now we have two real ways of doing things: <code><em></code> and <code><span class="footnote"></code>. Remember that <code>em</code> stands for <em>emphasis</em>. When you wish to apply emphasis to a word, phrase or sentence, stick it in <code><em></code> tags regardless of whether you want italics or not. If you want to change the styling in some other way, use CSS: <code>em { font-weight: bold; font-style: normal; }</code>. Of course, you can also apply a class to the <code><em></code> tag: if you decide you want certain emphasised phrases to show up in red, give them a class and add it to the CSS:</p> <pre><code>Fancy some <em class="special">shiny</em> text? em { font-weight: bold; font-style: normal; } em.special { color: red; } </code></pre> <p>If you're applying italics for some other reason, go with the other method and give the section a class. That way, you can change its styling whenever you want without adjusting the HTML. In your example, footnotes should not be emphasised—in fact, they should be de-emphasised, as the point of a footnote is to show unimportant but interesting or useful information. In this case, you're much better off applying a class to the footnote and making it look like one in the presentation layer—the CSS.</p>
