I am attempting to design a website header, but there is a persistent small gap in the top left corner that I just can't seem to fix

@import 'https://fonts.googleapis.com/css?family=PT+Sans';
 * {
  font-family: 'PT Sans', sans-serif;
}
#headerpanel {
  display: block;
  background-color: red;
  width: 100%;
  margin: 0px;
  padding 0px;
  border: 0px;
}
<title>Test Site</title>
<body>
  <div id="headerpanel">
    TEST
  </div>
</body>

My objective is to design a "header" that spans from the far left to the far right of the website, positioned around 20px from the top.

However, upon testing, I noticed a small space in the top-left corner... How can I eliminate it?

Answer №1

body,html { 
  margin:0px;
  padding:0px;
}

Answer №2

To adjust the default margin style of the browser for body, you simply need to reset it.

body {
    margin: auto;
}

Take a look at your box model by using the "Computed" tab in your browser's IDE or developer tool.

Answer №3

Include the code snippet below in your CSS file

body{
  margin:0;
}

Answer №4

Get rid of the left margin on the body

@import 'https://fonts.googleapis.com/css?family=PT+Sans';

* {
    font-family: 'PT Sans', sans-serif;
}

#headerpanel {
    display: block;
    background-color: red;
    width: 100%;
    margin: 0px;
    padding 0px;
    border: 0px;
}
body{margin: 8px 0px; }
<title>Test Site</title>
<body> 
<div id="headerpanel">
TEST
</div>
</body>

Answer №5

It seems like there may have been a misunderstanding with your question or with the responses provided by others. Typically, setting margin: 0; resolves the issue, but some browsers such as Safari and Chrome may still display a small border. In this case, using top: 0; left: 0; will align the element with the edge of the page.

@import 'https://fonts.googleapis.com/css?family=PT+Sans';
 * {
  font-family: 'PT Sans', sans-serif;
}
#headerpanel {
  position: fixed;
  display: block;
  background-color: red;
  top: 0;
  left: 0;
  right: 0;/* since we are moving it left a little, we use right: 0; instead of width: 100%; */
  margin: 0px;
  padding: 0px;
  border: 0px;
}
<title>Test Site</title>
<body>
  <div id="headerpanel">
    TEST
  </div>
</body>
