⟩ How To Remove the Top White Space of Your Web Page using CSS?
The top white space of your Web page is provided by the browser's default CSS definition of the margin-top property on the BODY tag. You can remove this white space by adding your own margin-top definition. Because of the cascading order rules, your definition wins over the default definition. Here is a CSS example:
<html><head>
<title>CSS Included</title>
<style type="text/css">
BODY {margin-top: 0px}
BODY {background-color: white}
P {font-family: arial; font-size: 12pt; color: black}
</style>
</head><body>
