footer does not cover the entirety of the length of the page - html

Question

This is my first time writing in html and css, so sorry if it's confusing and dumb.
I'm trying to make that sticks to the bottom and covers the length of the page, the problem is that i tried everything i could, from padding to width:100% other thant searching online, what can i do?
I'm using angular and i have installed bootstrap, please don't hesitate to ask any question or to ask me to explain myself (i'm not a native speaker), have a nice day and thank you!

Answer 1

The standard way to align a footer at the bottom of a webpage is just by setting it to position: relative;. However, this entails that there is more content that is equal to or greater than the viewport height. Hence, aligning the footer after the content and at the bottom.
If you don't have content, use position: absolute; on footer. Then you can set bottom: 0px; to get it at the bottom. Then set left and right to 0 to get it the full width. See below.
