For the tee shirt

Posted by: c00ler

What current bug in the w3c’s CSS validator affects how you specify units of measure? It’s a new bug, causing valid css to be marked as no good. The first time we noticed it was on, you can see the “fix” for it in our css. First correct answer gets the Hot Tee.

    According to the CSS spec, you are allowed to declare line-height values without declaring a unit of measure. The default unit is ‘em’, so a perfectly valid declaration like this:

    p {font: bold 1.4 Georgia, serif;}

    Really means this:

    p {font: bold 1.4em Georgia, serif;}

    However, the current iteration of the W3C’s CSS validator currently returns an error if you do not include a unit of measure when declaring line heights. This is inconsistent with the CSS spec, and thus is a bug that should be fixed.

    I think the bug is :
    line-height: 0 generates parse error -

    You fixed it with “line-height:0px;”

    Okay, I was hasty in my first response. The bug is only in reference to the actual “line-height” declaration, and it only crops up in the case of integers. Thus, the following examples will all validate:

    p {line-height: 1.3em;}
    p {line-height: 1.0em;}
    p {line-height: 1.3;}
    p {line-height: 1.0;}

    But this will return an error:

    p {line-height: 1;}

    The workaround is to add a decimal to the value (1.0), or to bite the bullet and add the unit (1em).

    Wow, and we thought an elusion to line-height would be necessary; fat chance - You guys are on point. Dane definitely did that switch w/ mad style, but Ara rode away clean too, with the example of our fix & link to Bugzilla. Thankfully, we’ve got enough tees to go around, so if Dane & Ara could email me an address (bill at ghettocooler dot net), I’ll get em in the mail!
