Microsoft has a toolbar introduced which is helpfull to web developers. They can check compatiblity with W3C standards for html and CSS. As stated on their website:

"The IE Developer Toolbar provides several features for deeply exploring and understanding Web pages.

• Explore and modify the document object model (DOM) of a web page.
• Locate and select specific elements on a web page through a variety of techniques.
• Selectively disable Internet Explorer settings.
• View HTML object class names, ID's, and details such as link paths, tab index values, and access keys.
• Outline tables, table cells, images, or selected tags.
• Validate HTML, CSS, WAI, and RSS web feed links.
• Display image dimensions, file sizes, path information, and alternate (ALT) text.
• Immediately resize the browser window to 800x600 or a custom size.
• Selectively clear the browser cache and saved cookies. Choose from all objects or those associated with a given domain.
• Choose direct links to W3C specification references, the Internet Explorer team weblog (blog), and other resources.
• Display a fully featured design ruler to help accurately align objects on your pages"

When designing websites and no texts are yet delivered by your customer you need "Lorem Ipsum"

"Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. "

I found a site which generates "Lorem Ipsum" texts for you :)
