How do I get rid of the white space that comes around the border in CSS?
Question
I was just messing around with CSS & HTML and added a header with a background color to the top of my website. Then I saw that there was lots of white space on top of the header's background color and to the sides of it. How do I get rid of this white space using CSS? Here is my code along with a picture of how the website looks right now:
<!DOCTYPE html>
<html>
<head>
<title>
Website
</title>
<link rel='stylesheet' href='style.css'/>
<script src='script.js'></script>
<link href="https://fonts.googleapis.com/css?family=Open+Sans" rel="stylesheet">
<link href="https://fonts.googleapis.com/css?family=Baloo+Bhaina" rel="stylesheet">
<link href="https://fonts.googleapis.com/css?family=Nunito" rel="stylesheet">
<style>
.typeofvirus{
font-family: 'Open Sans', sans-serif;
}
br {
line-height: 2%;
}
#topheader{
background-color: #2c3e50;
width: 100%;
color: white;
margin-top: -1%;
}
html, body {
margin: 0px;
padding: 0px;
}
</style>
</head>
<body>
<p></p>
<section id = "topheader">
<div id = "topheaderdiv">
<h1 style = "font-family: 'Baloo Bhaina', cursive; text-align: center;"><big>Hello</big><br><small><small><small style = "font-family: 'Nunito', sans-serif;">This is a webpage</small></small></small></h1>
</div>
</section>
<h2 class = "typeofvirus">What are Microbes?</h2>
<p></p>
<h3 class = "typeofvirus"><big>Types of viruses caused by microbes in the bathroom</big></h3>
<ul>
<li style = "font-family: 'Open Sans', sans-serif;"><i><big>Dermatophitic fungi</big></i>: Caused by people walking barefoot in bathrooms</li>
<li style = "font-family: 'Open Sans', sans-serif;"><i><big>Gastrointestinal viruses</big></i>: Caused by contact with a toilet. This can remain on a solid surface for over a week. This causes stomach ailments.</li>
<li style = "font-family: 'Open Sans', sans-serif;"><i><big>Residual fungi</big></i>: which can cause asthma or allergies. This is caused by the mold in the bathroom due to lack of cleaning.</li>
</ul>
</body>
</html>

You need to reset your body and html margin and padding too:
Add this to your CSS:
html, body {
margin: 0px;
padding: 0px;
}

I would go with anned20's answer but for the sake of academic curiosity you can also add
overflow: hidden;
to body and html. Or manually give the element a negative upper margin and a 100% width like this
#topheader{
background-color: #2c3e50;
width: 100%;
color: white;
margin-top: -1%;
}
But, again, anned's solution is ideal.
