Absolute URLs refer to the entire URL which includes the server and the page. Any links that take you outside of the website you're linking from must link to an absolute URL.
- example: http://www.nancymacleod.com/page.html
- example: images/dog.gif
A relative URL is for files that are on the originating server, like images or other pages in a root or subdirectory.
What is the advantage of managing files, i.e. renaming, moving and deleting files, through Dreamweaver's Files Panel?
You can compare the files you have on your server (remote site) and use the file menu to synchronize those with your local files so it will only upload the files you have changed. It will also analyze all the media assets (dependent files) associated with the file you want to upload and copy those files to the server too.
What is the significance of a page named index.html?
It's the page that will be landed on if someone just enters the URL. That way people don't have to know a specific page name just to access the site.
What DOCTYPE should you be using for your pages?
XHTML 1.0 Transitional
Why is <em> and <strong> preferred over <b> and <i>?
<em> for emphasis has more of a semantic meaning while <i> for italics is more of a style consideration. The same with <strong> versus <b>. Also if a speech reader for the visually impaired is used, it will emphasize words with <em> but not <i> and use strong emphasis with <strong> and not <b>. This can change the meaning quite a bit if not used correctly.
This is a recommendation of the Web Accessibility Initiative (WAI).
