These are simple graphic image buttons created in [Art Text 2] which have been linked to the named sections of this site. I have used a Rich Text pagelet for ease of centring the buttons in the pagelet area. I have change the pagelet to a Callout for ease of seeing on this page. The dotted line to show a link is determined by the site Design. If I was clever, I sure there is a way to change that for a local area. As I am not, I will leave it as it is.

Above left: Screenshot of menu with underlines -- no active links!

Update:
I've added the <h1> tag around the images, above right, (in Raw HTML mode of Sandvox) which suppresses the dotted line but increases the space between the images.

• The <h1> spacing of the buttons makes them very easy to use on an iPhone.
