Why inttelij takes my html for query request ?

Hi, since yesterday when i write for exemple

div.ui.dividing.header 

to make 

<h3 class="div ui dividing header">Commentaires</h3>

i cannot press tab nothing happened but i have the bulb which says " run query in console" i think i did something wrong because before it works. I think it interpreted my html tag for query request.

 It's in a *.ejs, i specify that because in a *.html i don't have this problem

What can i do ?

Thanks
