Autoprefixer missing

[gtbu]

Typesetter uses the inbuilt Scss-compiler for Bootstrap - for older bootstrap3 the less-compiler. Both compilations contain vendor - prefix-mixins (ps : sorry - overseen :_vendor-prefixes.scss and vendor-prefixes.less).
The bootstrap4-compiler of 5.1.1 hasnt - but RC5.2 has now (manually added ) automatic vendor - prefixes.
(The Smartstrap-templates use the bootstrap.css but have no prefixes for the stylesheet.)

There are solutions for the rest (normal css-templates and for the stylesheets):

1. add the postcss-autoprefixer as a plugin (which is used by the bootstrap-developers) and rewrite the compilation - process (but postcss is node).
2. add a CSS preprocessor like Css-Crush (also git) and rewrite the minification - process
3. Use stylish.js (non-php) - no minifier
4. for non - bootstrap templates there is a online prefixer .

• Another limited and often incompatible solution would be to add LeraVerous Prefixer to the templates
