( #3333=superdoc: print w/replies, xml ) Need Help??
UPDATE: Don't know if it applies to PM's home-grown tags, styles, etc, but that would not be legal in w3c .css.

Only a single class is allowed within the tag it "modifies."

See Ven'Tatsu's below. He is correct and my statement was wrong. (Next para is still true, but less relevant to css vers > 2.0

<sometag class="1" style="2; 3; 4;">

is allowed, but 2, 3 and 4 must be defined css elements. I'n not aware of any good way to make them refer to "roll-your-owns."

UPDATE: However, read also the note at the end of §5.8.3 at http://www.w3.org/TR/CSS21/selector.html

Typical (and ugly) workarounds involve creating compound styles

.c { text-align: center; } .cb { text-align: center; font-weight: bold; } .cbr { text-align: center; font-weight: bold; color: red; background-color: transparent; } .cbri (or whatever, ad nauseum)...

or the even-uglier use of multiple <span> tags; eg

<p class="c"><span class="b"><span class="r">fubar whatever.... </span +></span></p>

UPDATE: To my mind the "compound" style declaration above is on the same order of ugliness as the multi-classing in w3c's pages cited in this node and in Ven'Tatsu's. It may, however, be more readable.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
