    Thank you for this!

    I have a few questions:

    Can you install a child theme after you have already installed and configured a parent theme or will this undo all of your work?

    Do you really need a child theme if you are only adding css under the customizer or will that remain in place over when you update your theme?

    Also, if do need the child theme and you have placed css under the customizer on the parent, should you move it over to the child?

    • WPBeginner Support says

      You can install a child theme but you may need to set some of the settings in the original theme for your design.

      If you are only adding changes in the customizer then a child theme is not required.

      For safety, we would recommend moving CSS in the customizer on the parent to the child theme. :)

    Great article. What happen if I am just using parent theme and not activate the child theme after install it.

  4. Hannah Joy says

    Thank you so much!!! Every other online tutorial was so confusing and added a lot of irrelevant detail or confusing and inapplicable info. I am creating a website for the first time and not trying to do anything fancy, I just want to get it right from the start. So grateful for pages like yours that break it down into easy to chew bits for us newbies!!

    Thank you for sharing this, it is very helpful.
    I have one question..
    I have already installed the parent theme and created pages, menus, etc.
    I’ve come to installing the child theme because I need to create an endpoint in WooCommerce. I’ve done most of my site, just doing the finishing touches.

    When I deactivate the parent theme, and activate the child theme, will it keep all the work I’ve done? Or will I lose it all?

    • WPBeginner Support says

      You would keep all of your pages and content. Other customizations to styling may not transfer depending on the specific theme.


  6. Annapurna Agrawal says

    Hey, I have this serious question. Which one should I opt for? Creating a child theme? or building a theme from scratch?

    If I create the theme from scratch, how do I manage the updates to functions in WP?

    If I create a child theme, I will basically have to update the entire style for my website.

    Help me get out of this!

    • WPBeginner Support says

      If you create a child theme it will use whatever customizations you’ve added and if you do not specify a style it will take that from the parent theme. Creating a new theme would require you to have a style rule for everything you want styled.
      You would update the functions as you would with any theme.

    Hi, I have installed both Genesis and child theme Essence. While I love the framework, I don’t care for my theme. Do you have any articles or suggestions on how to install & switch child theme’s? Thanks in advance!

  8. Susana says

    If I have already activated the parent theme should I deactivate it before installing and activating the child theme?

    • WPBeginner Support says

      Hi Susana,

      You can only activate one theme at a time in WordPress. When you install and activate the child theme it automatically deactivates the parent theme. You can also manually deactivate it if you want. However, you will need to keep the parent theme installed to use the child theme.


      • Mayur Lokhande says

        I have installed Parent theme, I don’t know how to check weather I had installed child-theme or not. Why is there need to upload child theme. If one would not install child theme then what would happen?

        • Paul Mohan says

          The child theme makes it a lot easier to edit wordpress sites later without expert knowledge.

  9. Juan says

    How do I create a child theme if wordpress was not installed locally on my pc. During the installation I left the “Directory” section blank and I think that is why I do not have a local install. What are my options?

  10. Allan Seabrook says

    Hi Syed,

    Thanks for sharing this article. Recently, I have started experimenting with the “One-Click Child Theme” plugin by tychay. It hasn’t been updated in two years by the developer. but appears to work as documented.

    Have you had any experience with this plugin or anything similar?


  11. Anton says


    What should I do if I already use main parent theme? How can I add child one? Do you guys have guide for that too?))

  12. Markus Martin says

    Hi Syed. I don’t know if it is only me, but my customizations in style.css for child theme don’t work anymore and am forced to use the custom css in wordpress customise dashboard. Is there a difference and is that really ok?
