Before uploading your site to a server and declaring it ready for viewing, its a good idea to test it locally. (In fact, its a good idea to test and troubleshoot your site frequently throughout its construction--you can catch problems early and avoid repeating them.)
You should make sure that your pages look and work as expected in the browsers youre targeting, that there are no broken links, and that the pages dont take too long to download. You can also test and troubleshoot your entire site by running a site report.
The following guidelines will help you create a good experience for visitors to your site:
Your pages should be legible and functional in browsers that do not support styles, layers, plug-ins, or JavaScript (see Checking for browser compatibility). For pages that fail badly in older browsers, consider using the Check Browser behavior to automatically redirect visitors to another page (see Check Browser).
This gives you an opportunity to see differences in layout, color, font sizes, and default browser window size that cannot be predicted in a target browser check (see Previewing and testing pages in browsers).
Other sites undergo redesign and reorganization too, and the page youre linking to may have been moved or deleted. You can run a link check report to test your links (see Checking for broken, external, and orphaned links and Fixing broken links).
Keep in mind that if a page consists of one large table, in some browsers, visitors will see nothing until the entire table finishes loading. Consider breaking up large tables; if this is not possible, consider putting a small amount of content--such as a welcome message or an advertising banner--outside the table at the top of the page so users can view this material while the table downloads.
You can check your entire site for problems, such as untitled documents, empty tags, and redundant nested tags (see Testing your site).
Publishing your site--that is, making it live--can be accomplished in several ways and is an ongoing process. An important part of the process is defining and implementing a version-control system, either with the tools Dreamweaver includes or through an external version-control application.
The forums are a great resource for getting information on different browsers, platforms, and so on. You can also discuss technical issues and share helpful hints with other Dreamweaver users.
