HTML and CSS Reference
1. Different users will have different levels of experience. Browser preferences will
vary. Some want to see a lot of multimedia, whereas others prefer none at all.
Some prefer images and multimedia that are interactive, whereas others prefer sim-
pler pictures that demonstrate a process or technique on how to do something.
Other preferences are more specific to the interests of the visitors.
2. Include pages on your site that help tvisitors find the information they're looking
for. Also include pages that help them find their way around the site.
3. Two things you can do to start migrating to HTML5 are to start using the HTML5
DOCTYPE and to stop using the tags and attributes that were removed from
HTML5 in your pages.
4. False. Too many frames can be confusing for new users, and they might be too
small to be useful when they're viewed at lower resolutions.
5. False; however, you must use the images in an accessible manner.
6. Navigation should be placed after the main content on a page to make it accessible
with users who must navigate the page in a linear fashion.
7. Some attributes designed to improve accessibility are the title attribute of the <a>
tag, the longdesc and alt attributes of the <img> tag, and the summary attribute of
the <table> tag. Remember, though, that longdesc and summary have been
removed from HTML5. It is recommended that their content be incorporated into
the page in another way.
1. Design a simple navigation system for a website and describe it in a manner that
makes sense to you. Then ask others to review it and verify that your explanations
are clear to them.
2. Make a list of the topics that you want to discuss on your website. Go through the
list a second time and see whether you can anticipate the types of people who will
be interested in those topics. Finally, review the list a third time and list the special
needs that you might need to consider for each user group.
3. Visit Cynthia Says, the accessibility validator, and see how your site rates against
the accessibility guidelines.
4. Make sure that all the <img> tags on your site have alt attributes. It's a good first
step toward accessibility.
