CSS is used to create boxes with arrows that point towards content. These are often used as tooltips and quick instructions that pop up to guide you along a website. This tutorial shows how to create these divs with arrows, and the logic behind the CSS code. Here's the code block used in this tutorial: //The main box .arrowBox{ width: 200px; height: 30px; background-color: #ffc728; border-radius: 5px; position: fixed; top: 3em; left: 230px; padding: 10px; font-family: Roboto, sans-serif; font-size: 14px; line-height: 22px; color: #313333; text-align: center; } //The arrow pointer .arrowBox:after{ content: ' '; width: 0px; height: 0px; border-top: 10px solid #ffc728; border-left: 10px solid transparent; border-bottom:10px solid transparent; border-right:10px solid transparent; position: absolute; left: 50%; top: 100%; margin-left: -10px; } Background music by: YouTube Free Music (End of Summer, and Pas de Deux)
