Allow me to briefly doff my hat at Andrewds' diligence; your patience and continued assistance in this thread (over 300+ messages and counting)haven't gone unnoticed. Well done.

Mountain, I do suggest perusing the many Help pages available when you have the time; they do cover quite a bit of ground. It sounds like Help:Tabber could be of use to you. If by "chang[ing] tabber box sizes" you mean you'd like to change the width of the box 'below' the tabs--

(and I suspect you do, now that I see the tabber on the Dearborn Dash article is extending 'behind' the infobox)

--then yes, you can change the default dimensions of boxes and make many other customization to tabs besides via CSS. The styling 'code' provided on Help:Tabber includes the basic tabber elements you can copy to your in-use CSS page and customize to your liking. For instance, if you wanted to make the width of all tabber boxes a firm 500px, you could try replacing "/* tabber wrapper style */" with "width: 500px;" in that stylesheet.

If you wanted to adjust the width of just one tabber on a particular page, e.g. Dearborn Dash, you could try experimenting with sandwiching the tabber code between

, i.e. adjusting the percentage value to your liking. However, you'll have to accordingly adjust the widths you're using for the table; using Dearborn Dash again as an example, I'm referring to the two usages of:

style="width:300px;"

If you do want to give indiviudal styling via div style a try, here's some values you can try using as a test run:

...followed by replacing both 300px usages with 200px. Again, these values aren't necessarily formal suggestions, just values to toy around with after testing them. Don't forget to close the div tag after you've closed the tabber tab; if you'd rather customize tabber unformly, then definitely do so via CSS.
