In order to remove the blue link color from a hyperlink we must do what is called clearing the formatting.

In order to to this:

1. Edit the page on which the links exist.
2. Using the visual editor highlight the desired links.
3. Click the “Formatting” menu list
4. Select “Clear Formatting” from the list
5. Click off the selected links

You should see that the blue formatting that was previously being applied to the hyperlinks is now removed.

See it in action below:

Different file types are better suited for different image types.

GEEK SPEAK:
The main thing to consider is image compression. JPEGs can handle image compression whereas PNGs cannot. PNGs end up creating an index of every color used in an image. If you have an image that has a gradient or a wide range of colors all that data ends up being stored in the PNG image file causing the file to size to get really large really quickly.

The general breakdown is to use PNGs or GIF image formats for solid colors and to use JPEGs for TIFF image files for things like photos, or anything that has a gradient.

When working with links in a text block a couple rules need to be followed to remain in compliance with the ADA.

1. If the link is *inline with text then it is NOT a button.
2. If the link is inline with text but not **in flow it MUST be a button.

This is demonstrated in the image below where the red represents a piece of linked content.

Definitions:
*inline with text – In this context, this refers to a link that is used inside of a text block.
**in flow – In this context, this refers to a link that is used inside of a text block but is not used inside a block of text and is meant to be separated.
