How to get what you want from HTML

How do you make a banner resize to exactly fit the width of a window?

Include "width=100%" in your img tag, e.g.,

<img width=100% src=http://www.how10.com/images/70ptLogo.gif>

How do you leave a specific amount of blank space in an html document?

Use a transparent image that is a single pixel in size, and specify the desired height (or width) inside the image tag, e.g.,

<br clear=left><img src=http://www.how10.com/images/trans.gif height=20><br clear=left>
