The Child Themes are the separate themes that entirely rely on the parent theme to access most of their functionalities. In case you are already using a child theme on your portal then the WordPress will first scan your child theme to check if a particular feature exists. If it doesn't then, it will use the parent theme for the same. This feature is great as it allows the portal owners to make any particular modifications.
Even if you plan to change a single character in your main theme, you should create a child theme so that you can quickly carry out these small modification tasks without hampering the overall design & layout. You can also get yourself the desired theme by opting for HTML to WordPress conversion services. There are two excellent reasons why you should build a child theme for your portal. You will read more about these reason in the next few paragraphs.
If you don't create any child theme for the modification of your website get you will have two choices: the first you can opt not to update your theme in the future, or else you can upgrade, but then you will lose all the changes that you've made in your theme.
The second choice would technically work, but it is not recommended as you have to start everything from scratch. Apart from that, not updating your theme will lead to various security vulnerabilities and will also increase the downtime. No matter what happens, you should always keep your theme & plugins up-to-date.
When you decide to add modification code in your WP theme, you will be adding that code to the existing codebase which already consists of thousands and thousands of lines. In the case of any error, it will become tough for you or the developer to track down the issue in the codebase.
Even if you have to make any minor change to the outlook of your site, you should always create a child theme so that you don't have to go through the massive codes that will only make your modification task more time-consuming and costly. Usually, child themes have less line of codes which makes it easier for the developer to detect any issue or to make any changes.
