Programming Tips - How can I make a nice looking box in html?

Date: 2015dec23 Language: html Q. How can I make a nice looking box in html? A. I'm no designer but I think something that works is having the border a color that's close to the background color. The background not too dark (so text is readable). And rounded corners.
<style> .mybox { border: 3px solid #888; /* Gray border */ background: #ccc; /* Background is also gray - but lighter */ border-radius: 10px; /* Rounded corner */ margin: 10px; /* Generous amount of margin and padding */ padding: 10px; } </style> <div class=mybox> This box fills nearly the whole page width </div> <p/> <span class=mybox> This box is only as wide as the text </span>
