To change the theme in Shopify, you can follow these steps:

1. Log in to your Shopify admin dashboard:

– You’ll be directed to your Shopify admin dashboard.

2. Access the Online Store section:

– This will take you to the online store management area.

3. Choose the “Themes” option:
– In the online store management area, click on the “Themes” option.
– This will display the available themes for your Shopify store.

4. Explore and preview themes:
– Browse through the available themes to find the one you want to change to.
– Shopify offers a variety of free and paid themes. You can use filters and search options to narrow down your choices based on features, industry, or style.
– Click on the “Explore free themes” or “Explore paid themes” button to see the available options.
– Use the “Preview” button on each theme to see how it will look on your store.
– If you cant find a suitable theme try searching 3rd party theme websites such as ThemeForest (www.themeforest.net).

5. Select a new theme:
– Once you have found a theme you like, click on the “Actions” button for that theme.
– From the drop-down menu that appears, select “Publish” to immediately apply the theme to your store.
– Alternatively, you can choose “Preview” to see how the theme will look without making it live.

6. Customise the new theme (optional):
– After selecting a new theme, you may want to customise its settings to align with your brand and preferences.
– Click on the “Customise” button for the new theme to access the customisation options.
– This will open the theme customisation view where you can modify various aspects like colors, fonts, layouts, and more.
– Customise the theme according to your needs and preferences.

7. Save and publish the changes:
– Once you have customized the new theme, click the “Save” or “Publish” button to make the changes live on your storefront.
– If you initially chose the “Preview” option, you’ll need to click “Publish” to apply the theme to your store.

8. Review and refine:
– After changing the theme, review your store across different pages and devices to ensure that the new theme is displayed correctly.
– Pay attention to the layout, navigation, typography, and any customisations you made to ensure everything looks as intended.

Please note that changing the theme may affect the appearance and functionality of your store. It’s important to review the new theme thoroughly and test it to ensure that it meets your requirements. Additionally, some themes may have specific settings and options that differ from others, so take the time to explore and familiarise yourself with the customisation options provided by your new theme.
