I have following line in my page:
<a href="#" rel="toggle[home_right_animate_div1]" data-openimage="/images/right_btn1_hover.png" data-closedimage="/images/right_btn1.png"> <img src="/images/right_btn1_hover.png" border="0" alt="" /> </a> When I check this for HTML5 validation I'm getting following errors:
Error: Bad value toggle[home_right_animate_div3] for attribute rel on element a: The string toggle[home_right_animate_div3] is not a registered keyword.


rel="toggle[home_right_animate_div1]"this line is giving validation error..
