How to change TextField display style in code?

[siegersallee]

I hope this is simple; it seems like it should be.

How would one change the colors and border style of a TextField, in code, directly (without editing the .css file)?

For example, if I want a field to have #555 on #CCC with no border, sometimes.

Please give example code, if you can. I tried several approaches, none of which worked. It could be that I tried a slight variation on what you have in mind, and the missing detail will only be clear with an example.

Thanks!

We haven't created an API to do this, because there's no need - even if the CSS is fully dynamic (user chosen, specific to that one session) you can still create CSS classes dynamically in the browser.
