There is a select with 2 white and black values.

You need to change the value of the white class to the black class and back to white, depending on the selection. On all div

<select id="sel" name="sel" class="theme"> <option value="white">white</option> <option value="black">black</option> </select> <div class='white'> main <div class='white'> content1 </div> <div class='white'> content2 </div>

Javascript or jquery

Please, help.

 .white{ color:red; } .black{ color:green; }
