Add WordPress CSS using a theme
To edit WordPress CSS via a theme, it’s a good idea to create a child theme first. This way you rest assured you’re not deleting the changes you made by updating the theme. The most important adjustments are made in the stylesheet, which is used to embed CSS in HTML. You can easily access this from your dashboard. You won’t need any additional programs or editors and can also make changes via FTP.
Via the dashboard
To customize WordPress CSS follow these steps:
- Back up your WordPress website. This prevents errors from disrupting your entire online presence. If you haven’t done so already, create a child theme.
- Log into the backend.
- Search for the style.css file. This is your stylesheet. You can locate the file in the menu in “Appearance” > “Theme File Editor”.
- A pop-up window will launch with a warning to not make changes to files. If you’ve created a child theme and backup already, then you’re on the safe side. Agree and continue.
- Now you can edit the CSS. Be aware that most of the changes will be applied globally. So you’re not only editing a specific area, but every page and subpage that contains the area. To edit a specific subpage only, specify it first.
Via the FTP client
Even if you don’t have access to the Theme Editor or prefer not to use it, you can edit the CSS in WordPress. All you need is an FTP connection to your website.
- Install the FTP client.
- Log in using your FTP account data.
- Your stylesheet should be in “wp-content”. You’ll also find a subfolder with the name of your theme and the style.css file.
- Right-click the file and select “View/Edit” to make changes.
- Once you’ve finished editing, save the file and upload it to the server.

Edit WordPress CSS using Customizer
For individual adjustments and to check changes immediately, the Customizer is a useful option. You won’t need a child theme and any update to the theme won’t delete your progress. However, if you choose to add a new theme, some or all of your changes may not be applied. The steps are as follows:
- Create a backup to prevent possible errors.
- Log in to the backend.
- Find the Customizer under “Design” in the left-hand menu.
- Scroll down and click “Additional CSS”.
- This launches an interface to enter your code into. With live preview, you can monitor in real time how changes made to the WordPress CSS will appear. The Customizer points out errors in the code.
- If you’re satisfied with your edits, save the changes, publish them or schedule them for publication.
Note that when using the Customizer, changes are applied to all subpages unless specific pages are selected.
