Im having trouble with my body's height

Hi, I’ve been working in this project and have struggled a lot with centering things in place and setting body’s height. I don’t know why it starts with some weird margin and even tho I’ve tried setting html to 100% can’t make my body cover my whole page. (i also had trouble with user agent style sheet).

So far, my page is able to take to a random page and load results (it can’t take the input yet) after you press enter, i want the body to cover the whole page so there would be space under the last link.

Sorry for my English, is not my native language

Thanks in advance, Santiago.

I really can’t understand where is the problem (there is a space under the last link), but try adding
box-sizing: border-box;
in your CSS * selector.

Like this:

* {
  margin: 0;
  padding: 0;
  -webkit-margin-before: 0;
  -webkit-margin-after: 0;
  box-sizing: border-box;
}

i tried, but it didn’t work,

.
im not being able to get body cover the whole page.

(Thanks a lot for the answer)
