Typography can tell a story.  If text is large, it is important.  If it is bolded, it definitely is important to what was Large that preceded it on a page.  Let's learn more about typography.

Whole books have been written about Typography, what it is, what it means, how to use it, what typestyles can say to a reader.  But let's start with what is Typography.  First and foremost, it is text.  Yep, that's right, it is text, just like you are reading now.  However, you want to emphasize what the text is saying when you create a page in a website, or a banner or ad in a newspaper.  You also want to make sure it is large enough for a reader to be able to see it when you consider what they are reading from.  Is it a banner?  Make sure it is large enough to be read quickly!  Is it a newspaper ad?  You can squeeze in a lot of material by using a smaller size type.  This means you get more bang for your buck.

In a website Typography is a mixture of all of this.  And more.

You can use color to set a mood.  You can add a color box around the colored text.  You can outline the important text, or add a link to this whole ball of wax and make it a button link.  All of the coloring makes it stand out on a page, a Call to Action, and hopefully the readers will see it and decide if this is something they want to do.
