layout your forms using CSS instead of tables.
I am a fan of using CSS for layout and presentation of web pages - but I do still have a few 'blind spots' when it comes to putting my good intentions into practice. For example, I still tend to use tables when creating layout for forms.
I was recently alerted to this weeks tip by Tavis Reddick, the webmaster at Fife College; while communicating about another forms related issue, he pointed me to a useful article about using CSS to layout forms (scroll down the page to find the part about forms layout).
I won't reproduce the example code here - because it is not the simplest technique I have come across - and I couldn't figure out a way to simplify it for 'tip size' consumption. However, I thought it was worth highlighting this example, as it demonstrates that CSS is flexible enough to be used for tasks beyond the simple two or three column page layout.
