Here are some examples using the old-fashioned html tags:
If there is no tag, the text will take on the default font style, size and color determined by the browser.
Font families
ariel or helvetica or another sans-serif
verdana is another sans-serif
times the serif font
georgia, a "fancy" serif type
courier
Type size: This line of text has the default size with one exception.
Type color: You can set a part a different. It's determined right here in this line of type.
Or you can set the whole paragraph a different color.
You can mix it all up, too!
and you can make text bold, or italic or even strike-through
