By using the Custom view portlet you can adjust a dynamic web site to be displayed by the visitor´s choice. Here the visitor can select text size, line height, font and contrast. This is usable for increasing the accessibility for among others the users that need a larger font.
OBSERVE! If you have absolute templates you may instead use the portlet Accessibility - or if you just want to change the text size - the portlet Style resize.
A tip for accessibility! To improve visibility on your web site for people with disabilities:
Use relative measures
Avoid presenting text as images. The text becomes unclear and hard to read when enlarged.
