The Dilemma: Updating Themes vs. Custom CSS

You’ve poured your heart and soul into crafting the perfect look for your website.

The colors the fonts the layout everything is just right.

But then the dreaded update notification pops up reminding you that your theme needs a refresh.

It’s a common struggle especially for those of us who’ve invested time in custom CSS to make our sites truly stand out.

The fear of losing those carefully crafted styles can be daunting.

Imagine spending countless hours making your WooCommerce store’s product pages look absolutely stunning only to lose those customizations during a theme update! It’s a nightmare scenario that could lead to a chaotic unpolished user experience and even a drop in sales.

Thankfully there are solutions!

Securing Your CSS: A Step-by-Step Guide

1. Backup Backup Backup!

This might sound obvious but it’s the cornerstone of a smooth update process.

Before you even think about updating your theme create a full backup of your website.

I’m talking about your database theme files plugins everything.

This backup is your safety net your insurance policy against any potential data loss or disruption.

Now if you’re using a premium WordPress hosting service like Pressable you’re already in a good position.

Most of these services include automated daily backups.

This means you can relax a bit more knowing that even if something goes wrong you can easily restore your site with a few clicks.

2. Embrace the Power of Child Themes

This is where things get truly interesting.

Instead of adding custom CSS directly to your theme create a child theme.

Think of it as a safe haven for your customizations.

A child theme is essentially a lightweight extension of your parent theme.

It inherits all the features and styling of the parent theme but it gives you a dedicated space to add your custom CSS without messing with the core theme files.

The best part? When the parent theme gets updated your child theme remains untouched preserving all your painstakingly crafted styles.

How to Create a Child Theme

Step 1: Create a new folder within your theme’s directory. Name it something like “my-child-theme.”
Step 2: Create a file called “style.css” inside the new folder. Here’s a template you can use:

/*
Theme Name: My Child Theme
Theme URI: https://www.yourwebsite.com/
Description:  Child Theme for 
Author: Your Name
Author URI: https://www.yourwebsite.com/
Template: 
Version: 1.0
*/

Step 3: Add your custom CSS directly to this style.css file.

Now you can update your parent theme with confidence knowing that your custom CSS is safely tucked away in your child theme.

3. The Power of Staging Environments

Before unleashing a theme update on your live website you want to test it thoroughly.

That’s where staging environments come in.

A staging site is a clone of your live website where you can experiment update and test without affecting your live visitors.

If you’re using Pressable creating a staging environment is as simple as clicking a button.

This makes testing updates a breeze allowing you to identify any potential conflicts or bugs before they hit your live site.

Why Staging Is Crucial

Think of a staging environment as a dress rehearsal for your website update.

You get to try on the new theme see how it interacts with your plugins and ensure that your custom CSS still plays nice.

It’s far better to catch any issues in a staging environment than on your live site where it could affect your visitors and potentially damage your reputation.

4. Updating Your Theme: Two Methods

Once you’ve set up your staging environment you can update your theme.

There are two primary methods:

a) The Dashboard Approach

This is usually the simplest and most convenient way to update your theme.

Just navigate to the “Appearance” section of your WordPress dashboard then to the “Themes” tab.

Find your theme click “Update Now” and follow the prompts.

b) The SFTP Method

This method offers more granular control and is helpful if you need to update the theme directly from your file manager or if you’re dealing with specific update requirements.

Updating via SFTP

Step 1: Connect to your server: Use an SFTP client like FileZilla to connect to your server. You’ll need your server’s IP address username and password.
Step 2: Navigate to your theme’s folder: Find the folder containing your theme files.
Step 3: Download the latest theme files: Get the updated theme files from the theme developer’s website.
Step 4: Upload the updated files: Overwrite the existing files in your theme’s folder with the new ones you downloaded.
Step 5: Test thoroughly: Don’t forget to test the update thoroughly on your staging site.

5. Testing Is Key: Don’t Skip This Step!

After you update your theme whether through the dashboard or SFTP it’s absolutely critical to test everything.

Make sure the update hasn’t disrupted your site’s functionality layout or your precious custom CSS.

What to Test

Layout and Styling: Check that all elements are displayed correctly that the colors and fonts are still on point and that your site looks just as you intended.
Functionality: Test all the forms buttons links and other interactive elements. Ensure everything works seamlessly.
Responsiveness: Make sure your site looks great on all devices from desktops to mobile phones.
Plugin Compatibility: Verify that your important plugins still work correctly with the updated theme.
Performance: Use tools like Google PageSpeed Insights to assess your site’s performance. An update might sometimes introduce minor performance issues that need to be addressed.

Don’t Let Issues Stop You

If you encounter any problems don’t panic! You can revert back to the previous theme version.

You can also use your backup to restore any lost CSS.

Going Live: Confidence and Caution

Once you’ve tested everything meticulously on your staging site and are confident that the update is flawless it’s time to deploy it to your live website.

Choose a time of low traffic to minimize any disruption to your visitors.

Live Site Deployment

Step 1: Update your live theme: Go to the “Appearance” section of your dashboard navigate to the “Themes” tab and activate the updated theme.
Step 2: Monitor closely: Keep a close eye on your live site after the update. Check key pages functionality and make sure everything is working as expected.

Keep Your Backup Handy

It’s always a good idea to have a recent backup readily available just in case.

If you encounter any unexpected issues after the update you can quickly revert to your backup to get your site back up and running.

Theme Switching: Preserving Your Style

What about when you’re ready to switch to a brand new theme? The good news is that you can still preserve your custom CSS.

1. Transferring Your CSS

Step 1: Create a new child theme for your new parent theme.
Step 2: Copy your custom CSS: Open the style.css file in your old child theme and copy the code that contains your customizations.
Step 3: Paste into your new child theme: Paste that CSS into the style.css file of your new child theme.
Step 4: Test and adjust: You might need to tweak some of the CSS to work correctly with the new theme’s structure. Test thoroughly on a staging site before deploying to your live website.

2. Advanced CSS Management

For more advanced CSS management you can directly add CSS to the functions.php file of your child theme.

function my_custom_css() {
    // Your custom CSS code here
    echo '<style>';
    echo 'body { background-color: #f0f0f0; }'; 
    echo '</style>';
}
add_action( 'wp_head' 'my_custom_css' );

This method allows you to control how your CSS is applied and integrated with the rest of your theme.
