Unlike <H1> to <H6>, the <font> tag is an inline element, and therefore, tag does not force a new line. The <font> tag requires a closing </font> tag at the end of the text being formatted. Do not close the attribute settings as they close automatically with the closing </font> tag.

From an initial <basefone size="1-7>tag, you can increase or decrease my font size relative to the basefont (or the default size which is "3".

<font size="-2">
<font size="-1">
<font size="+1">
<font size="+2">
<font size="+3">

The previous line is at the maximum size of 7 (<BASEFONT="4"> plus <font size="+3">). The following lines use <FONT SIZE="digit"> to define a specific size font and are not dependent on the <BASEFONT>. Valid values for the attribute SIZE are 1-7.

<font size="1">
<font size="2">
<font size="3">
<font size="4">
<font size="5">
<font size="6">
<font size="7">

Comparing Font Sizes

Using the deprecated tag <FONT> to set the size of your text, permits the user to enlarge your text up to double the size, using the center "wheel" on their mouse. By setting your font size using CSS (Style) you lock the size and prevent it from being resized by the user.

Below, the colored text was set using <font size="n"> where "n" is a number from 1 to 7. Above the scaleable text, is the original size of the text, locked in by using <span style="font-size: xx pt">. Below the scalable text is another line of of text, again set using <span style="font-size: xx pt">, but this time showing the MAXIMUM size a user can scale your text to. To avoid the user scaling your text, and thus destroying the great look you put into your webpage, set all your text size using CSS.
