Following these steps, ensures a smooth way to change theme.

Q2: What are the steps to install Magento theme?

There are 2 ways to install Magento theme: manually or via Composer, depending on whether the theme is distributed as a set of files or a Composer package. Though Composer offers a straightforward method, not all themes are available in this format, necessitating manual installation at times.

 Manual Installation:

  1. Upload Theme Archive. Use an SFTP client to upload the theme archive (e.g., .zip, .tar) to your Magento user’s home directory.
  2. Extract Archive. Unpack the archive in a separate folder to review its contents before copying to the Magento filesystem.
  3. Copy to Magento Directory.  Copy theme files from the extracted folder to the Magento directory, typically stored in app/ and pub/ folders.
  4. Change Magento Mode. Switch to developer mode, clear generated classes, and execute necessary commands to set up the theme.
  5. Install Theme via CLI. Run commands like `php bin/magento setup:upgrade` and `php bin/magento setup:static-content:deploy -f`.
  6. Verify and Apply Theme. Log in to the admin panel, enable the theme for your store view, and save configurations.

 Installation via Composer:

  1. Install Magento Theme. Add the theme using its Composer name to composer.json and update dependencies with `composer require`.
  2. Verify and Apply Theme. Confirm successful installation and apply the theme using the steps outlined in the manual installation.

To identify the installed theme, navigate in the admin panel: Content → Design → Configuration. From there, click the ‘Edit’ button in the ‘Action’ column corresponding to your preferred store view.

How to figure out which theme is already installed on a Magento website?

Q4: Is it possible to choose a specific page or section to change theme? So the website has a few themes at the same time.

No, it is not possible to select a specific page or section for changing the theme. However, you may apply different themes for different stores. For instance, you can use “Theme A” for your store in English and “Theme B” for the store in German.

Q5: What kind of conflicts or problems may arise when changing themes?

The process to change theme is full of pitfalls and it depends a lot on how the theme has been installed. Most common problems fall into the following groups: Styling Inconsistencies, Functionality Issues, Customization Challenges, and Compatibility with Extensions.

In my experience, the fundamental problem arises when using Virtual Type, leading to potential functionality issues. Additionally, problems may arise with imported blocks and other elements, causing the deletion of previously existing blocks.

Q6: Can I change theme on my own, without technical expertise or the assistance of specialists?

Yes, you can change theme in the admin panel. But what needs to be done before this?

The theme needs to be installed on the server, and this is impossible without technical knowledge. For example, to manually install Magento theme, you need to go to the server, add the theme archive to the specific location and unpack it. Then, you need to do the deployment, and for this you need to execute a list of commands: 

php bin/magento maintenance:enable

rm -rf var/di/* var/generation/* generated/* var/cache/* var/page_cache/* var/view_preprocessed/* var/composer_home/cache/*

#composer update

php bin/magento setup:upgrade

php bin/magento setup:di:compile

php bin/magento setup:static-content:deploy -f

php bin/magento indexer:reindex

php bin/magento cache:clean

php bin/magento cache:flush

php bin/magento maintenance:disable

So you definitely need some technical knowledge here in order not to mess up.

Q7: What mistakes do specialists make when changing a theme?

Basically, no mistakes happen if you work with professionals. But there are exceptions, when you need to install themes developed by incompetent teams. This is when unpredictable issues happen, related to:

  • CSS Styles and Design
  • Functionality Issues
  • Extensions Compatibility
  • Responsive Web Design

Q8: How to adjust or change the colour scheme?

This is done only in code (usually the entire CSS) and mainly not for the whole theme, but for some specific elements on the pages. There are themes that have custom settings for changing colours, then this can be done directly in the admin panel, without technical knowledge.

Q9: How do I modify the fonts or other text styles in the Magento theme?

This is typically done through the code. However, for static pages using Page Builder, you can achieve this by making changes within Page Builder for a specific page.

Q10: How can I ensure that the new theme is properly displayed across various devices (responsive design)?

If the theme initially provides responsive design, then it’s pretty straightforward. Simply view the site on the devices you are interested in. It’s also a good idea to check for cross-browser compatibility using
