it will still function properly regardless of the width being set to zero

Is anyone able to explain the strange phenomenon I am experiencing with this code snippet? In this particular example, I have set the width of selector h3 to 0. However, when viewing it in IE 9 using F12 development tools, I can see that the width is indeed 0, yet the text within the h3 element is still displayed, even though it clearly exceeds a width of 0. How is this possible?

<!DOCTYPE html>
    <html>
    <head>
        <meta http-equiv="content-type" content="text/html; charset=utf-8" />
        <title>Chapter 5: Indestructible Boxes</title>
        <style type="text/css" media="screen">
           body 
           {
              font-family: Arial, sans-serif;
              font-size: small;
            }

            h3
            {
               background :blue;
               width:0px;
            }
        </style>
    </head>

    <body>
    <h3>Gifts and Special Offers v Gifts and Special 
        Offers Gifts and Special 
        Offers</h3>
    </body>
 </html>

Answer №1

Include overflow: hidden; in the CSS:

p
{
   color :red;
   height:10px;
   overflow:hidden;
}

Answer №2

Typically, the width attribute is not appropriate for the < h3> tag. If you want to conceal it, try this CSS:

h3
{
   display: none;
}

Answer №3

To hide the text of an h3 element, you have a couple options:

 h3
        {
           background :blue;
           width:0px;

          overflow:hidden
        }

or

     h3
            {
               background :blue;
               width:0px;
               display:none
        }
