Checkpoint 1.7 - Blogs

Relatively sized text allows users to have some control over the size of font they wish to view by adjusting settings in the browser. Absolute sized text can not be manipulated in the same manner. The screen resolution of the user's browser may make the text difficult to read if absolute sizing is used and the user is not able to adjust text size manually.

Requirement

Use only relative font sizes in the blog entry.

Recommendation

Text must be resizable to enable users to have some visual control over font size via their browser settings. This should be done using percentages (%) or ems (em). Text size is to be specified in the stylesheet.

Resize the text on the browser to the smallest size and to the largest size to test that the page is usable.

Checking Tool

• Internet Explorer - AIS toolbar: IE Options > Text Size > Largest/Smallest
• Firefox : Ctrl + to increase font size; Ctrl - to decrease font size
