HTML
<section> <div class="shape"></div> We are not quite sure of any one thing in biology; our knowledge of geology is relatively very slight, and the economic laws of society are uncertain to every one except some individual who attempts to set them forth; but before the world was fashioned the square on the hypotenuse was equal to the sum of the squares on the other two sides of a right triangle, and it will be so after this world is dead; and the inhabitant of Mars, if he exists, probably knows its truth as we know it.</section>
CSS
section { max-width: 400px; } .shape { float: left; width: 150px; height: 150px; background-color: maroon; clip-path: polygon(0 0, 150px 150px, 0 150px); shape-outside: polygon(0 0, 150px 150px, 0 150px); shape-margin: 20px; }
