Semantic UI
"Semantic is a development framework that helps create beautiful, responsive layouts using human-friendly HTML."<p>Claims made without evidence can be dismissed without evidence.<p>I'm not singling out Semantic UI here except to say that usability studies validate beautiful, responsive layouts using human-friendly HTML.<p>Has anybody done a usability study to confirm any such claims?<p>Again, not singling out Semantic UI except to point out an opportunity. Semantic UI could be the first to quantify this by providing usability study support rather than just putting it our there.<p><a href="https://www.nngroup.com/" rel="nofollow">https://www.nngroup.com/</a>
