So while building this website, I wanted wanted to use some sort of wysiwyg editor to make it somewhat easy to add new posts and pages. I messed around with the HtmlBox, CLEditor, jwysiwyg, and CKEditor editors, and liked them but they were kinda buggy and would take a lot of time to customize. While building the site in the beginning I went with SKEditor because it did have a lot of features that I liked, but still i was stuck on how to add different things or how to change some things, including makign it HTML5 compatible.
Then I found MarkItUp and practically fell it love. Its so easy to use, and customize which I did a lot of. I think for programmers this is a good one to use as it will make it easy to add coding to you textarea box and still understand it. As for clients websites, it should help them learn how to code if they would use it, you just have to let them know how to use the preview button correctly to check their posts before they submit it.
Anyways, I added a few things that I figured some people would like to add to their own as well. Some of the features i added include the blockquote / quote tag, youtube videos, syntax highlighter, Map Quest, images floating to the left or right, font styles, and my own gallery with help from the mark it up website. Below are my changes, and I'll also describe how I got everything working.
