How to change background color in Replit HTML?

Published in HTML & CSS 2 mins read

The provided reference describes changing the theme (light or dark) within Replit, rather than directly manipulating the background color of an HTML page. To change the background color of your HTML in Replit, you'll need to use either inline CSS, internal CSS (within a <style> tag), or an external CSS file. Here's how:

Using Inline CSS

This is the simplest method for a quick change. Add the style attribute directly to the <body> tag or any other relevant HTML element.

<body style="background-color: lightblue;">
  <h1>Hello, Replit!</h1>
  <p>This is a paragraph.</p>
</body>

In this example, the background color of the entire page is set to light blue. You can replace lightblue with any valid CSS color value (e.g., red, #FF0000, rgb(255, 0, 0)).

Using Internal CSS

This method involves placing CSS rules within the <head> section of your HTML document using the <style> tag.

<!DOCTYPE html>
<html>
<head>
  <title>Background Color Example</title>
  <style>
    body {
      background-color: lightgreen;
    }
  </style>
</head>
<body>
  <h1>Hello, Replit!</h1>
  <p>This is a paragraph.</p>
</body>
</html>

This code sets the background color of the <body> element to light green. The CSS rules within the <style> tag apply to the corresponding HTML elements.

Using External CSS

This is the most organized approach, especially for larger projects. Create a separate CSS file (e.g., style.css) and link it to your HTML document.

style.css:

body {
  background-color: lightcoral;
}

index.html:

<!DOCTYPE html>
<html>
<head>
  <title>Background Color Example</title>
  <link rel="stylesheet" href="style.css">
</head>
<body>
  <h1>Hello, Replit!</h1>
  <p>This is a paragraph.</p>
</body>
</html>

The <link> tag in the <head> section tells the browser to load the styles from the style.css file. This keeps your HTML clean and separates concerns. Make sure the href attribute correctly points to the location of your CSS file.

In summary, to change the background color in Replit HTML, use inline CSS, internal CSS within a <style> tag, or, for better organization, create and link an external CSS file.
