[header] How to improve the usability of your website [title] Make sure the typography of your content is suitable. [step] If you have large blocks of text, make sure to use css to space out the lines accordingly. The longer a single line of text is, the greater the line-height of each line should be. 
Also, make sure the font size of your text is big enough to read easily. Some sites have 10-pixel-tall text in verdana font; while that may look neat and tidy, you have to really strain your eyes to read the actual text.
