There is no such thing as an unstyled HTML element. Every webpage uses at least one CSS: the User agent Stylesheet.
The user agent stylesheet
This CSS file is included in the browser and is called:
- every time a webpage is rendered
- before any of our CSS is applied
Although each browser has its own User agent CSS, they are all fairly similar.
Applying a CSS reset
A browser’s default styles can interfere with the styles we actually want to apply. That’s why a CSS reset has been devised to provide a consistent base across all browsers.
It’s particularly useful for normalizing the text size and removing all margins.
You can find (and download) the HTML 5 reset.css of this website. Just include it in your
<head> before your own stylesheet.
