Question

i have a code like this

 <li role="presentation"> <a href="#Twistato" class="rounded btn" aria-controls="Twistato" role="tab" data-toggle="tab"> Twistato </a> </li>; 

I get a symbol like an image below

can anyone tell me what this symbol is or its name or how I can find it

Answer 1

actually it was a dropdown icon which was given a default value

 .the-menu-custom-nav .nav-tabs > li > a:before { content: '\\f0dd'; top: 7px; } 

i removed and its fine now
