ruby on rails css behaviour

Question

im working on a rails project version 3 and i can't figure out how this happens. there is no css since this is a brand new project.

why do i get this margin? is this a rails convention?

is there any standard css used by rails if you do not set up a reset-css-file?

chrome:

this is how the html gets generated by rails:

Answer 1

Google Chrome applies a default property of body { margin: 8px; } body { margin: 8px; } to all webpages that don't specify their own margins.

Answer 2

Many browsers have default styles that may change how elements are displayed by default. If you want to start from an clean slate you should look into using a CSS reset style sheet. I prefer this one by Eric Meyer, however there are others you can look into using.
