Answer 1

Like this :

.arrow {     border: solid 10px transparent;     border-right-color: #FFF; }

UPDATE :

It can also be achieved without empty elements with the css property :before

element:before {     content: "";     position: absolute;     top: 50%;                         // half way down (vertical center).     margin-top: -15px;                // adjust position, arrow has a height of 30px.      left:-30px;     border: solid 15px transparent;     border-right-color: #FFF;     z-index: 1; }
