You can dim a background image in WordPress without writing any code. It only takes a couple of minutes, and it’s much easier than most people expect.

WordPress includes a simple setting that lets you add a transparent color overlay to any background image. This helps your text stay readable while still showing off your design.

In this guide, I’ll walk you through exactly where to find the option and how to adjust it. It’s one of the fastest ways to improve your site’s design without changing anything else.

Quick steps to dim a WordPress background image:

What Is a WordPress Background Image?

A WordPress background image is any image that appears behind the main content on your website. For example, you can have a background image behind everything like this:

Or you can show an image behind specific content elements like sidebars, footers, headers, and more.

These images add interest to your website and can help keep visitors engaged with your content. They’re also essential to your business branding, helping users differentiate your site from your competitors.

Why Should You Dim Background Images in WordPress?

Sometimes, background images can make it difficult for visitors to read your content. Take a look at this example:

Hard to read background image text

It’s pretty hard to see what the text says because the background image is so vibrant.

Yet if you darken the background image, you can make the content stand out more, making it easier for visitors to read, learn more about your products and services, and become potential customers.

After setting up your page, you can return to this tutorial to learn how to darken your background images.

Since we’re creating a WordPress theme for this tutorial, you’ll need to navigate to SeedProd » Theme Builder from your WordPress admin area and click the Themes button.

Choose a Website Kit in SeedProd

On the next screen, you’ll see a gallery of website kits you can use to create an instant WordPress theme.

SeedProd Website Kits

Each kit comes with all the pages and theme templates your website needs. You can then customize each page with SeedProd’s drag-and-drop page builder.

Scroll through the kits until you find one that suits your business, then hover your mouse over the kit thumbnail and click the checkmark icon.

Choose a Website Kit

After importing the website kit, you’ll see a list of the parts that make up your new WordPress theme. To customize any part, click the Edit Design link, and it will open in the visual page builder, where you can add your custom background image.

Edit your homepage design

Let’s start by editing the Homepage design.

Step 3: Add Your Background Image to WordPress

When you open a template in SeedProd’s page builder, you’ll see a layout similar to the example below.

SeedProd's page builder layout

There are blocks and sections for adding content on the left and a live preview of your design on the right with elements used in your website kit.

You can customize your template easily by clicking any element on the preview. This will open a panel with settings for that element and customization options.

You can also drag a block from the left onto your page to add more content, such as optin forms, social media icons, videos, images, buttons, and more.

Add content to SeedProd design

Adding a background image to any section is just as easy. Click the area you want to edit, and delete the default background image.

Change a section backround image

You can then upload a new image from your computer or WordPress media library.

Step 4: Add a Transparent Overlay to Dim Your Background Image

As you can see in our previous example, the background image we’re using doesn’t contrast enough with the headline, making it hard to read.

Fixing this is super easy and takes only a few clicks. Simply find the Dim Background heading in the section settings and drag the slider to the right until your heading stands out.

You can also use the same panel to add a color overlay to your background image. This is an excellent way to link your brand’s colors into your web design and make your site more recognizable.

To do that, find the Overlay Color heading and click the color picker to select a custom color. Choosing a color is quite simple. You can point and click to find a color that works or use the arrows to enter a:

  • Hex value
  • RGBA value
  • HSLA value

This is an excellent solution if you already know which color you want to use. 

You can also:

  • Adjust the background image position
  • Change the background color of a section
  • Use a gradient instead of an image
Change the background image position

For example, clicking the drop-down arrow lets you position your background in the following ways:

  • Full Screen Cover
  • Full Screen Cover – Fixed
  • Full Screen Contain
  • Full Screen Contain – Fixed
  • 100% Width Top
  • 100% Width Bottom
  • Background Repeat
  • Repeat Horizontal Top
  • Repeat Horizontal Bottom
  • Repeat Vertical Center
  • Custom Position

Choosing the Custom Position option opens more detailed customization options.

Custom background image position

For instance, you can change the X or Y position to show a specific portion of your image. You can also change the attachment type to fixed or scroll, set how the image repeats, and change the background size.

As a result, you can tailor each area of your background images to achieve the perfect look and feel.

FAQs on Dimming Background Images in WordPress

Can I dim just part of a background image in WordPress?
No, WordPress doesn’t support selective dimming natively. However, tools like SeedProd let you apply overlays to specific sections, rows, or columns — so you can create the effect of partial dimming by targeting only those areas.
Do I need a plugin to dim a background image in WordPress?
Not always. If your WordPress theme includes a built-in overlay option, you may be able to dim background images using theme settings. But if you want full control without touching code, using a plugin like SeedProd is the easiest way.
What color overlay should I use to darken a background image?
Dark gray or black overlays with 40–60% opacity work best for readability. You can also use a brand color overlay to stay consistent with your design while improving contrast.
Will dimming my background image affect SEO?
Not directly. But if dimming improves readability and helps visitors engage with your content, it can lead to lower bounce rates and more time on page — both of which support better SEO performance.

If your background image looks great but makes your text hard to read, dimming it is a simple fix that can transform your page.

I showed you how to do it with SeedProd using the Dim Background slider and optional overlay color. You can use this for full-width hero images, section backgrounds, or even sidebars — anywhere you want better contrast without losing your design.

The best part? You don’t need to mess with CSS or theme files. Just drag, adjust, and publish.
