I normal do webparts based in
Content Editor -> using url to
.html file. Works very well.
Now I need to add in html a reference for boostrap CSS file. The big question is, the boostrap css file will overwrite SharePoint CSS styles, so some SharePoint features crash.
Any one know a workaround? I don´t want to use full boostrap in SharePoint site, because I want to design people change color font size etc, throw SharePoint theme editor.
