Question

Can anyone give me details on each?

for example?

Is #ID an attribute or property or selector or anchor?

Is default property and default attributes are different thing?

Are all these Tags or elements?

What we will say to this

<img src="angry.gif" alt="Angry face" title="Angry face" />

This

<div>.....</div>

and these

<br /> , <hr />

Syntax , Tag or elements?

Thanks in advance.

Answer 1

In:

#menu ul li {
  display: inline;
}

we have:

• Selector: #menu ul li;
• Property: display;
• Property value: inline.

In:

<ul id="menu">...</ul>

we have:

• Element or Tag: <ul>;
• Attribute: id;
• Attribute value: menu.

Edit: Ok, to address this issue of tags vs elements.

Both the XML and HTML 4.01 specifications use the terms:

• Start Tag: <ul>;
• End Tag: </ul>; and
• Element <ul>...</ul>.

However, in colloquial usage, such distinctions are so rare that there are arguments about it. In normal use the terms are interchangeable even though that it not their precise definition.
