<!DOCTYPE html> <html> <head> <style> .div1 { float: left; width: 100px; height: 50px; margin: 10px; border: 3px solid #73AD21; } .div2 { border: 1px solid red; } .div3 { float: left; width: 100px; height: 50px; margin: 10px; border: 3px solid #73AD21; } .div4 { border: 1px solid red; clear: left; } </style> </head> <body> <h2>Without clear</h2> <div class="div1">div1</div> <div class="div2">div2 - Notice that the div2 element is after div1, in the HTML code. However, since div1 is floated to the left, this happens: the text in div2 is floated around div1, and div2 surrounds the whole thing.</div> <h2>Using clear</h2> <div class="div3">div3</div> <div class="div4">div4 - Using clear moves div4 down below the floated div3. The value "left" clears elements floated to the left. You can also clear "right" and "both".</div> </body> </html>
