Better CSS compatible HTML code
The HTML Code should be more variable with CSS. Every Tag should have a unique class. The Name should be a h2 or h3 tag, not an list and bold tag and so on....

With the new Joomla 3 with bootstrap and LESS it is absolutely necessary to have the option to change the CSS file for a LESS file with @import variables.less
or at least an option not to use the current joomgallery.css
