All you have to do is visit Paste HTML, enter some code, publish it, and look at what you made. Paste HTML supports HTML, CSS, and JavaScript. You can even use Markdown if you want.

A simple copy-and-paste sequence works great for moving content from a webpage to another location. You will, however, need a place to paste websites in a text-style format.

Copy the code from elsewhere by selecting it, right-clicking it and clicking "Copy." Right-click where you want the code in your blog's HTML source and click "Paste" to insert the code.
