WordPress Tutorial: How to change the background color of your login page

Learn how to personalize your WordPress login page by changing its background color using a simple code snippet. This step-by-step tutorial will help you enhance your site’s branding while keeping it fast and lightweight—no plugins required. Follow our guide to create a custom login experience that aligns perfectly with your business identity!

The Problem 🤔

The default WordPress login page comes with a plain background that doesn’t reflect your brand identity. Unfortunately, WordPress doesn’t offer a built-in option to customize this, leaving your login page looking generic and out of place. If you want a professional and cohesive design, you need to take matters into your own hands. The good news? It’s easier than you think!

The Solution 🤓

Customizing the background color of your WordPress login page is simple and requires only a few lines of code. By adding this code to your theme’s functions.php file, you can create a unique and branded login page without relying on plugins. Follow these steps to implement the solution:

1. Access Your WordPress Theme Files

Log in to your WordPress Admin Panel, go to Appearance > Theme File Editor, and select your active theme’s functions.php file. Alternatively, access the file through FTP or your hosting control panel.

2. Add the Custom Code

Insert the code below the description.

3. Save Your Changes

After adding the code, click „Update File“ to save your changes. Be cautious when editing theme files—ensure you’re using a child theme to avoid losing customizations during updates.

4. Test Your Login Page

Open your login page URL (e.g.,https://yourwebsite.com/wp-login.php) in a browser to see the updated background color. Clear your cache if the changes don’t appear immediately.

The Benefits of changing background color ✅
