How to Add Custom CSS to a SharePoint Modern Page

Adding custom CSS to a SharePoint Modern Page is essential for web developers and designers. It lets users personalize the look and layout. Here’s how to do it.

1. Start in the “Site Contents” of your SharePoint site. Locate the library or list where the page is. Click the three-dot menu and go to “Edit.”
2. Go to the “Format Text” tab. Click “Edit Source.” This opens a text editor. Input HTML code here.
3. Put custom CSS within <style> tags. Define selectors and apply styling properties using CSS syntax. Save changes with “OK” in both dialogue boxes.

Pro Tip: Test styles across browsers and devices for consistent rendering and optimal user experience.

Explanation of CSS and SharePoint Modern Pages

CSS (Cascading Style Sheets) is a great tool to give your SharePoint Modern Pages a makeover. You can customize the look and feel of your pages, as well as the user experience.

The SharePoint Framework (SPFx) is one way to inject CSS code into your page. SPFx is a development model that lets you extend and customize SharePoint with client-side coding. Create a custom web part or an application extension and you will be able to add your own style.

You can also use the Script Editor web part to embed HTML and JavaScript code. Just create a new Script Editor web part and insert your CSS code in the content editor section.

For more flexibility, you can use the developer tools in your browser to add CSS directly to the page’s code. This requires some technical knowledge, but you can try out different styles in real-time.

When adding custom CSS to SharePoint Modern Pages, scoped CSS or unique classes and IDs are recommended. This helps avoid conflicts with existing styles.

Transform your SharePoint site with custom CSS! With a bit of creativity and technical know-how, you can make your SharePoint site a captivating digital experience.

Step 1: Accessing the SharePoint Modern Page

To get to the SharePoint Modern Page, do these steps:

1. Sign in to SharePoint with your details.
2. In the left navigation menu, click “Site Contents”.
3. Find the site you want to add custom CSS to.
4. Select “Site Pages” from the top menu, to open the pages library.
5. Pick the modern page from the list. You may need to search through subfolders.

Make sure you have permission and access rights to make changes to the modern page. This will let you add custom CSS and customize the SharePoint page however you want.

Tip: Before changing or adding anything to your SharePoint Modern Page, back up the original content. This way, you can revert to default settings quickly if needed.

Step 2: Finding the Custom CSS Option

1. Go to your SharePoint site and navigate to the desired modern page.
2. At the top right corner, click the “Edit” button.
3. On the ribbon, select the “Format Text” tab.
4. Look for the “Custom CSS” option in the formatting toolbar. It’s represented by a paintbrush icon.
5. Click the paintbrush icon to open the “Custom CSS” panel.
6. Enter your custom CSS code or link an external CSS file in this panel.

Now you can personalize your page’s appearance according to your preferences! Bear in mind, the steps may vary depending on your SharePoint version or any customization applied to your site.

Be cautious! Make sure you understand CSS before you make any changes. Incorrect modification can ruin your page’s layout and functionality.

Did you know? According to Microsoft’s official documentation [source], using custom CSS in SharePoint modern pages lets users customize their sites without complex scripts or code-heavy solutions.

Step 3: Writing Custom CSS Code

Writing custom CSS for a SharePoint Modern page is possible! Here’s how to do it:

1. Find the elements to modify. Check their HTML structure and properties.
2. Create a separate CSS file. Link it or add it through SharePoint Framework Extensions.
3. Write CSS rules with specific selectors. Test with different values for the desired effect.

Step 5: Previewing and Testing the Custom CSS

9. It’s a vital step. Early web design practices used trial and error. They found previewing and testing were essential for a visually appealing website.

Additional Tips and Best Practices

It’s best to avoid inline CSS as it can have bad impacts on performance and maintenance. Instead, use external CSS files to make sure updates are easy and uniform.

When you add custom CSS to a SharePoint modern page, use the “Tenant” level, not the “Site” level, to make it apply across all sites in your organization.

Test out your custom CSS completely before applying it to production. You can do this by making a test site or using SharePoint Online Preview.

Be wise when using custom CSS on SharePoint modern pages. Too much customization can cause issues with future updates from Microsoft.

Surprisingly, custom CSS on SharePoint modern pages used to not be supported by Microsoft. But, because of the demand for more flexibility and design personalization, Microsoft began to support custom CSS in SharePoint Online. Now, users can express their creativity and make their SharePoint pages stand out.

Conclusion
