Most parts of html have a starting and ending tag. The beginning one has <what it is, most times a style tag can apply>,
Ex/
<p> This Is A Paragraph </p>
<p> This is linked to the <a href="https://en.wikipedia.org/wiki/Cat">Wikipedia Page On Cats</a></p>
<ul><p>This Will Be A List<p>
</ul>
Style tags are most commonly applied to text, but can also be applied to images
<p style="color: color; font-family: font"> This Is A Styled Paragraph. You do not need to add the style code to the end tag, because it will end at the same time as the paragraph. </p>
Some fonts you can use are: Garamond; sans-serif, Arial; sans-serif, Verdana; sans-serif, (default on neocities) Trebuchet MS; sans-serif, Times New Roman; serif, Georgia; serif, Courier New; monospace, & Brush Script MT; cursive. Remember that not all of these will show up on every device, such as brush script MT ad Courier New.
The span tag is used to only apply effects to certain parts of a paragraph, header, or other types of text. It is used in the list of fonts above.
<p>The alphabet is in Times New Roman:<span style="font-family:Times New Roman; serif">AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz</span></p>
