Responsive Website Links
Links on responsive page designs need special consideration since they must work well and give a good user experience on two very different devices - computers and touch devices.
Text links with contrasting and hover colors are outdated. They break up the flow of text and are pretty much useless on touch devices like the iPad and iPhone. A link for a touch device must have an easily viewable target area of at least 32px in width and height.
Image links would appear to be better in that they offer a large target area but how is the visitor supposed to know that the image is a link when they have no cursor to tell them that it is? Image links require either an icon or a descriptive caption and these may not be desirable options in many cases.
Modern web design has embraced the CTA (Call To Action) link - not just for its functionality but also for its eye catching prominence. A well designed CTA will not only be obvious but will make it hard for the visitor to resist clicking it.
Many of the widgets available on this site have CTAs built in but there are occasions when more are required such as below a block of text linking to more info, products or related services.
