Is it possible to have a uniform code for all merchants using a break tag after the description?

Most merchants use a <br /> tag but some don't like CompUSA for example. This means that there can either be a big gap in the page or text overlapping without it.

For example in the following example a merchant uses the <br /> tag:

Title here
Description Here
My custom details here

In the next example here is what it would look like if the merchant has no <br /> after the description:

Title here
Description HereMy custom details here

thanks in advance, hope this can be addressed for the benefit of all parties.
