Especially don't use blinking text for long sentences because it is very difficult to ready very long sentences that blink since the ready has to pause for the text to 'unblink' before they can read the rest of your long sentence. Sometimes the blinking text will be printed correctly and sometimes spaces will be printed where the blinking text should appear. When a user tells the web browser to print a page, the web browser effectively takes a snapshot of the screen and sends it to the printer. Sometimes that snapshot happens just as the text blinks off. Do not use frames .
Visitors find frames extremely confusing for navigating and printing.
A confused and frustrated visitor will quickly leave your web site and may not return. A good web site design can be implemented without using frames. If your designer suggests using frames, say no. Use bullet lists and numbered lists. And put a blank line between multi-lined items.
