Reasons not to include ul, ol, li on your CSS reset.
Based on Eric Meyer’s CSS reset on meyerweb.com he included ol, ul, li which was a great help on front-end developers.
Now when you are coding for a CMS (content manangement system) site you don’t want your clients to back to you and ask you why your ul bullets are not showing and your ol is not showing numbers on display. Remember not all clients have the ability to insert inline CSS styling to make bullets and numberings show up each time they will publish a new page.
So I keep my list elements as it is regardless of each various browsers output difference.
I reset margin and padding on the section where styling is not dynamic for end users like comment post, navigations, categories and etc. To keep the design crossbrowser compatible.
I suggest you should understand and study the style first before doing copy and paste.
This just my own approach on list elements, maybe I miss something so feel free to comment on this one.
