bootstrap - increase font size without site blowing up

A friend is helping me convert an existing html site to bootstrap.  Still have bugs to work out.  I am having problems modifying the css and having it display correctly without busting the columns all up.

Live site (html)

p.s.  Not sure why the font was set to tiny to begin with.  I can't even read it on my end on my desktop.  But when I change the font-size in body tag it pushes the columns all over the place.

Just amend the element font size values to a higher em.

I changed the p tag from .8em to 1em.  I uploaded file.  The font isn't changing.  Still looks microscopic.

Ah, now it is working.  Geez, hard to troubleshoot when there is a cache thang going on.  Right now, I really really really really really do not like bootstrap.  I hope I hang in there because it is supposed to be God's greatest gift to web masters.  Right now, it is the devil incarnate!

Changing a site to bootstrap is harder because you have things already setup the way you want which can cause conflicts sometimes fighting against BS's own styles.
You will find starting a site from scratch using BS will be a lot easier.

Why do fonts display so much smaller using bootstrap?  I mean geez, the p tag is set to 1.3 em which is normally what I set my h2 tags to.

does my personal css file overwrite the bootstrap.css file?

bring on the peas and happyness!
