Bootstrap3

[Ree]

I want to have all the links under the sidebar headings to line up with the same indent - actually if I could get Tags to lineup with Recent Posts and Archives, I'd be satisfied. There doesn't seem to be a margin or padding setting available when I Inspect with Firebug.

There is no margin or padding being set on the ul, which means the browser default is being used. In Firefox that looks to be padding-left: 40px;

If it were me I'd apply a margin-left: 0; padding-left: 40px; to the ul element (to ensure that the ul behaves the same way in all browsers, since they may not all use the same default as Firefox), then I'd also wrap the tags in a div with a padding-left: 40px;

Doing that should get things lining up for you.
