Buttons found in Blogs

[wryfhk22]

Wordpress for blogs is written in php. It allows users to highlight text and when they click the bold button, for example, the text becomes bold type. Similarly for italics, etc. Is it possible to do the same in Classic ASP. I know, of course, that you can surround text with bold tags but I’m asking about whether it’s possible to highlight text, click a button, and change the text like php.

Thanks,
