What is the advantage of collapsing white space?

The browser collapses the multiple white spaces into a single white space in
HTML.

This allows the developers to arrange the HTML code in a well organized and
legible format.

Is it possible to list elements straight in an html file?

Yes, it is possible with the use of indents.

Does a hyperlink apply only to text?

No. The hyperlinks can be applied to both text as well as the images.

It means that even the images can become clickable links with a capability
to take the visitor to the next page.

This can be done simply by using <a href> tag.

What hierarchy is being followed when in style sheets?

Inline style takes priority over embedded style sheets.

Embedded style take priority over external style sheets.

If a single selector includes three different style definitions, the definition
that is closest to the actual tag gets the priority.

What happens if the liststyletype property is used on a nonlist element like a
paragraph?

Here the property will be ignored without having any effect on the
paragraph.

What is the advantage of using frames?

Frames make it easier to navigate through a site.

The links that appear in the frame can appear through out the site.

How can I hide my source?

No. you can’t hide your source as it is required by the browser to display
your document.
