Hi there Thought some people might not know about this, and it's very helpful. If you need to use basic html and you don't know what you're doing (like me ) do a search for the phrase "free online html editor". You'll be able to create the effect you want in the editor and then click on "Source" then copy and paste the html to where ever you need it.
It's called a WYSIWYG editor.. Searching for that will provide much better results.. should you want to use one. The only place these are really useful is content posts. Like should you have someone who knows no code at all. But needs to be able to edit code... http://tinymce.moxiecode.com/ - TinyMCE is my favorite. And is easy to integrate with scripts. Most CMS's come with one, for obvious reasons.
