10. Tags (2)
• All HTML tags are made up of a tag name and
sometimes they are followed by an optional list
of attributes which all appear between angle
brackets < >
• Nothing within the brackets will be displayed by
the browser (unless the HTML is incorrectly
written and the browser interprets the tags as
part of the content).

11. There are a few HTML tags which do not
use an end tag and are used for standalone
elements on the page:
• <img> To display an image
• <BR> Line break
• <HR> Creates a horizontal line

16. Headings Element
Headings elements H1 through H6 are generally used for
major divisions of the document. Headings are permitted to
appear in any order, but for best results follow the
following:
H1: should be used as the highest level of heading, H2 as the
next highest, and so forth.
You should not skip heading levels: e.g., an H3 should not
appear after an H1, unless there is an H2 between them.
Don’t use headings to make text Bold or BIG, search engines
will use the text within headings to index your page.

24. Text formatting
Often <strong> renders as <b>, and <em> renders as <i>.
However, there is a difference in the meaning of these tags:
Today, all major browsers render strong as bold and em as italics.
However, if a browser one day wants to make a text highlighted
with the strong feature, it might be cursive for example and not
bold!
24
<b> or <i> defines bold or italic text only.
<strong> or <em> means that you want the text to be
rendered in a way that the user understands as
"important".
25. Character Formatting
<FONT SIZE=“+2”> Two sizes bigger</FONT>
The size attribute can be set as an absolute value from 1 to 7 or as a
relative value using the “+” or “-” sign. Normal text size is 3 (from -2 to
+4).
<B> Bold </B>
<I> Italic </I>
<U> Underline </U>
