Web design ‘pre-flight’ checklist
Over the years of being a freelance web designer, I’ve been developing my own processes for the business of designing websites. One of those processes has been compiling a list of tasks that need to be completed before launching a website, whether it be a new site or a redesign. This list is kept in a spreadsheet which I work through, ticking off each item after the client has given final sign off for the site to go live. I view it as my final quality control procedure and I usually find that the process will highlight a few of the ‘little things’ that I might have overlooked in general development. Usually nothing too major; more a case of ‘dotting all the Is and crossing all the Ts’.
Which is better for search engines: plain text or alt attributes?
Which is better in links from the search engines’ point of view: plain text or images with an alt attribute that says the same thing? For example, is this:
<a href="">This is a link</a>
better than this?
<a href=""><img src="" alt="This is a link"/></a>

Animated navigation items using jQuery
Dave Shea recently published an article on A List Apart (ALA), CSS Sprites2 – It’s JavaScript Time’, about how to use jQuery to create the effect of animated rollovers on navigation items.
The technique he outlines makes use of the same image replacement method as outlined in ALA’s original Sprites article. The problem with this method however is that it uses a large negative text-indent to remove the default text from screen, and with images turned off in the browser, you don’t see anything. This has accessibility implications not only from the perspective of those with disabilities, but also for those who deliberately turn images off, i.e. people on slower connections or those using handheld devices who are trying to limit the amount of information downloaded to their phone.

Chances are you do. Even if you don’t own a copy of Dreamweaver, it’s likely you would have come across the code it outputs for creating image rollovers in your travels looking at the code of other sites.
