Change style.fontWeight of Joomla! Articles Category Module

Question

I am setting up a feed that lists articles modified in the last 30 days. However, I would like this list to be of fontWeight:normal. The options within Joomla! only allow for heading style. I have access to the *.php files if necessary.

I have tried modifying the mod_articles_category.php already and was able to change everything but what I wanted.

I know one way is to trick the module by having a blank Month and Year Group, but then the list is tabbed over and the text is bunched up.

Any advice is greatly appreciated, thank you.

SOLVED:
Solved this by modifying the mod_articles_category.xml. I changed the value of JH6 to value="0".

EDIT:
I asked/wrote this question and its "solution" very early in my developing career. DO NOT do what I did. The correct method would be to alter the CSS as explained in the comments.
