how they create caption pointers

I'm not sure what you call them but typically when the designers wants the context of a box to focus on some part of the page they add a pointer to it. Referring to the small triangle i see in this project. How do they create these effects?

Refer to the ponter on the colorSelect

Hello,

Usually when I try to create this I use an :after statement.

For example you got a box.

     <div id="box"></div>

     #box {
          width: 500px;
          height: 500px;
          background: #000;
          position: relative; // don't forget :)
     }

     #box:after {
           content: " ";
           position: absolute;
           background-color: #000;
           background-size: 50px 50px; // apparently, :after needs an background-size, width and height
           width: 50px;
           height: 50px;
           transform: rotate(45deg); // I advise you to use prefixes for this to. (-webkit-, -moz-, -ms-, etc)
           display: block;
           bottom: -25px;
           margin-left: 50%;
           left: -25px;
     }
