A character entity is simply a simple sequence of characters
that HTML interprets as a single symbol.
Here are a few of the most common examples.
< makes the less than symbol used to open HTML
tags (<)
>makes the greater than symbol used to close HTML
tags (>)
is a special code that stands for "non-breaking space"
This is a symbol that you have to add if you want more than one space at a time,
because browsers will make multiple spaces into a single space, unless instructed
to do otherwise using this special set of symbols.
(Hint: Try stringing more than one of these t o g e t h e r.)
© makes a copyright symbol
(Notice that you may replace "copyright" with © in your page footers.)
& makes an ampersand symbol (&)
Practice using the above codes.
