Let me tell you a tale. For the longest time, we used a Xerox WorkCentre PE16 multi-function printer/scanner/copier/fax here in the office. It was an utter nightmare, and every time we tried to use it, the people next door could hear the screams of frustration.

For some reason, we lived with the thing for months–maybe years. The simple solution would have been to just replace it, but we just wouldn’t. Perhaps we were stubborn, perhaps we just never got around to it. We would always eventually get it to do what we wanted it to do and then get back to work.

Tensions mounted. The printer would ruin entire days and make the air of the office thick with anger. Finally, we couldn’t take it anymore, so yesterday, we finally did some troubleshooting.

We’d like to share this quick how-to with you.

• Use h1 as your page title; use h2 and on appropriately as sub-headings on the page. This provides an outline of your document.
• Use lists (dl, ol, ul) instead of manually placing numbers or bullets.
• Use address for any contact information on your page, including physical address, email address, phone numbers, and whatever else you would consider to be contact info.
• Use table on data best represented in rows and columns. Use thead and th to markup the column headings and tbody for the data itself.

Check the HTML spec for additional meaningful elements and get to work!

That does it for now. See you next time! Until then, read SEO and Validation.

Most of the embed code I see for Flash movies is invalid, usually containing the non-existent embed element or some-such. Even the code provided by YouTube for embedding videos contains embed. This can easily be thrown out and will—probably most of the time—instantly make your code valid.

Here’s an example (in XHTML) of a valid Flash embed that works in at least IE6+, Firefox, and Safari:

<object data="flash.swf" type="application/x-shockwave-flash" width="320" height="240">
<param name="movie" value="flash.swf" />
</object>

That’s all there is to it. Adjust the parameters and add additional param elements as necessary. If your Flash movie requires variables, just add an extra param as follows:

<param name="flashvars" value="arg1=foo&amp;arg2=bar" />

If you place additional elements inside the object element, it will act as a fallback, displaying if the Flash plugin isn’t installed. For example:

<object data="flash.swf" type="application/x-shockwave-flash" width="320" height="240">
<param name="movie" value="flash.swf" />
<img src="fallback.jpg" alt="Flash Didn't Load!" />
</object>

That’s all for now. Happy coding!

One thing I’ve started doing somewhat recently is adding a unique class name to the body element of each page. This allows me to write page-specific CSS as necessary without creating an extra stylesheet. Ideally, there should be styles for common elements that make up the site, rather than style for each page, but this can’t always be avoided. One case could be that a particular page needs to have a slightly different layout than the rest of the site. Body element class to the rescue!

Internet Explorer 6

We all know Internet Explorer 6 is a regular pain in the neck, right? Fortunately, it’s easy to add IE6-specific style with this selector:
* html [additional selectors...]

For example, the style * html p { font-weight: bold; } makes all paragraphs bold only in Internet Explorer 6.  It’s valid, but no other major browser will apply it. This is useful because sometimes the style needed to make things in IE6 look one way is drastically different than what is needed to make it look the same in all the other browsers. A simpler solution, though, is to tell your client to upgrade his 8-year-old browser.

“Navbars”

A site typically has a “bar” of navigational links. Vertically laid out navigation is easy to create and append additional links later. Horizontal navigation is sometimes desired instead, but it’s not always as trivial to append and can be a little trickier to achieve.

This tip will be focused on horizontal navigation. First, you should most definitely use unordered lists (the ul element) to organize your navigation links whether you’re using vertical, horizontal, upside-down, or anything-else-you-can-think of navigation. (See the W3′s excellent webmaster tips for more on unordered lists and their uses.) Once you’ve marked up your navigational links, jump over to the stylesheet and add a display: inline; line to your navigation’s li elements. Now take a step back and behold your now-horizontal navigational links!

If you find you need to set the width and height of your links, just set the display type of the a elements to inline-block, which I was surprised to find out was actually supported in Internet Explorer 6! Once you’ve set that, your links will behave like block-level elements as far as styling goes, but they will remain positioned inline. Sweet!
