===The BR tag===
Don't use BR tags to create visual space. Wrap your text in a P tag or a block level element such as a DIV and add a class or style if needed to control the visual space. The only appropriate place to use a BR tag would be for poetry, song lyrics and arguably address fields. When a screen reader encounters a BR tag it will stop reading, requiring the user to move forward to the next line manually. Making a double BR tag extra painful for users of assistive technology.
