Go to Exercise page

Solution:

HTML Code:

<!DOCTYPE html><!-- HTML5 document type declaration -->
<html><!-- Start of HTML document -->
<head><!-- Start of head section -->
<meta charset="utf-8"><!-- Declares document character encoding -->
<title>How to specify the height of the canvas</title><!-- Sets the title of the webpage -->
</head><!-- End of head section -->
<body><!-- Start of body section -->
Canvas Height <!-- Text indicating the purpose of the canvas -->
<style><!-- Start of inline CSS styling -->
#FirstCanvas{ <!-- Styles for the canvas element with id "FirstCanvas" -->
width: 500px; <!-- Width of the canvas -->
height: 300px; <!-- Height of the canvas -->
border: 3px solid red; <!-- Border styling for the canvas -->
background-color: green; <!-- Background color of the canvas -->
} <!-- End of styles for #FirstCanvas -->
</style><!-- End of inline CSS styling -->
<canvas id="FirstCanvas"></canvas><!-- Canvas element with id "FirstCanvas" -->
</body><!-- End of body section -->
</html><!-- End of HTML document -->

Explanation:

  • This HTML document starts with a doctype declaration indicating it's an HTML5 document.
  • Inside the <html> tags, the document structure begins.
  • The <head> section contains metadata about the document, such as character encoding and the title.
  • Within the head section, there's an inline <style> element for defining CSS styles.
  • The CSS styles define the appearance of the canvas element with the id "FirstCanvas". It sets the width, height, border, and background color of the canvas.
  • The <body> section is where the visible content of the webpage resides.
  • Within the body section, there's a canvas element with the id "FirstCanvas". It will be used to draw graphics or display other visual content.
  • The HTML document ends with the closing </html> tag.
