Markdown - StackEdit's HTML export template with highlighting by using Prettify or Highlight.js and personalized markDown.css

StackEdit is a Markdown Extra editor with MathJax (to display formulas using TeX Math syntax, see HERE if you are interested to show them on Blogger) and Prettify or highlight.js (for code highlighting) support.
It is a wonderful option when it comes to publish some HTML, even with a custom CSS!

Markdown is a text-to-HTML conversion tool for web writers. Markdown allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML).

If you are interested in more options to try, take a look at the article on Mashable.

The documentation, taken from the official GitHub project (it is even an opensource project), says:

StackEdit
=========

StackEdit is a free, open-source Markdown editor based on PageDown, the Markdown library used by Stack Overflow and the other Stack Exchange sites.

The wonder comes when you can set a custom template:

>Settings >Publish >Template

This makes possible to export a valid HTML which has included the script to load MathJax, Prettify and a custom CSS by going to:

>Save as... >Save using template

My custom CSS is an extension of the beautiful Markdown.css.
If you plan to use this modified style-sheet (the code is shown in the end of the post), it is better to download and host by yourself; remember to change the link in the template to your new location.

The Welcome Document of StackEdit will look as this (live preview):
