Tryit Editor v2.3

Edit This Code:
<!DOCTYPE html> <html> <head> <style> div.container { width: 300px; border: 1px solid; } div.box { width: 150px; border: 3px solid coral; float: left; padding: 10px; } </style> </head> <body> <div class="container"> <div class="box" id="box1">This is BOX1.</div> <div class="box" id="box2">This is BOX2.</div> <div style="clear:both;"></div> </div> <p>Two 150 pixels boxes inside a 300 pixels container. It should fit nicely, but because of the borders and padding, the two boxes take up more space than 150 pixels each. This "problem" can be solved by setting the box-sizing property to "border-box".</p> <p>Click the "Try it" button to set the box-sizing property of the two boxes to "border-box":</p> <button onclick="myFunction()">Try it</button> <script> function myFunction() { document.getElementById("box1").style.MozBoxSizing = "border-box"; // Code for Firefox document.getElementById("box2").style.MozBoxSizing = "border-box"; // Code for Firefox document.getElementById("box1").style.boxSizing = "border-box"; document.getElementById("box2").style.boxSizing = "border-box"; } </script> </body> <!-- Mirrored from www.w3schools.com/cssref/tryit.asp?filename=trycss3_js_box-sizing by HTTrack Website Copier/3.x [XR&CO'2014], Fri, 23 Jan 2015 07:51:23 GMT --> </html>
