vim - How does YouCompleteMe automatically complete css attributes and attribute values?

Question

After installing YCM, no other configurations are added to .vimrc.
Now JavaScript can be automatically completed (for example, if you enter Obj, a popup will automatically appear to let you choose the required completion), but css needs to be completed with omnicomplete by pressing [c-x] [c-o]. How can the css file be used? Autocomplete like JavaScript?

Answer 1

Put this code into your .vimrc and change the number 4 to your indentation setting

let g:ycm_semantic_triggers = {
   \   'css': [ 're!^\s{4}', 're!:\s+' ],
   \ }
