That’s because you are nesting a block level element inside the
p tag which is invalid. You can only nest inline elements such as
p tag. So your markup is invalid, consider making something like
<div class="inr_content clearfix"> <div class="col2 first fl"> <p>to provide a drive-in services.</p> </div> <div class="col2 last fr"> <p>to provide a drive-in services.</p> </div> </div>
From W3C :
The P element represents a paragraph. It cannot contain block-level
elements (including P itself).
