This template uses a CSS-based layout, which means that the page sections (header, sidebar, content, and footer) are positioned using CSS rather than within a table-based grid. Because this results in cleaner code, your pages load faster and search engines may rank your page better than they would in a table-based design.
When looking at your pages while in Design view, some elements may not appear correctly. Fonts may seem too large or small; spacing between elements may seem too wide, etc. While this can be a bit disconcerting, you will find it easy to keep previewing your site in a browser as you make changes. This will display your page correctly. To preview your pages, save the page after each change and then go to File > Preview in Browser.
Occasionally while editing your pages, you may “lose” the formatting. When this happens, save the page and then hit F5 to refresh your page. The page should snap back into position and the styles will return.
