Actually, at first, I just wanted to get in touch with sass (css preprocessor), but haml suddenly appeared.

The original text is Jiang Zi.

Sass is a CSS pre-processing language written in Ruby language. It was born in 2007 and is the largest mature CSS pre-processing language. It was originally designed to work with HAML (an indented HTML precompiler), so it has the same indentation style as HTML.

Damn it! haml? htmlA long-lost brother? This ignorant scumbag decided to search for what the hell is going on with a black question mark face

Baidu Encyclopedia is explained by Jiang Zi:

Haml is based on the Ruby language and is a Ruby plug-in that can also be used as a template language. It is a command line tool

Features:

1. Spaces indicate hierarchical nesting relationships

2. Good label format

3. DRY(Don’t repeat yourself)

4. Follow CSS standards

5. Integrated Ruby code

6. Use .haml extension instead of rails template (.rhtml)
