Alternative to TopStyle Pro

I have been doing CSS editing for many, many years and my tool of choice in the past has always been TopStyle Pro.  However, I recently discovered that this product is being discontinued since it was purchased by the makers of CSE HTML Validator: https://www.htmlvalidator.com/topstyle/

Therefore, as soon as I discovered this, I began looking for alternatives and fortunately I did not have to look very far to find a very good alternative by Blumentals called Rapid CSS Editor: http://www.rapidcsseditor.com/

It looks very much like TopStyle Pro and has around the same cost as the earlier license of TopStyle Pro of around $39.95 ($29.95 for a Personal license)!

Well, fortunately, this website provides a great breakdown of what features are and are not available in each of the various browser platforms: http://caniuse.com/

You can even do a browser comparison by choosing the browsers you want to compare!

Reference Guide for HTML5

With all of the new technologies that are related to ASP.NET MVC such as jQuery, jQuery Mobile, jQuery UI, jQuery Validation and Entity Framework, it is difficult to keep up with all of the new features in HTML5, therefore, I thought that I would provide a handy reference guide for anyone who simply wants a listing of the new elements or markup that can be used in HTML5.
