I think if you don't want to go with code again and again then you can go with Wordpress like CMS.
Wordpress (CMS) is software that helps you create, manage, and modify content on a website without needing to interact directly with the code.
You can simply create a website without much effort. If you want to convert your HTML website to Wordpress then you can also do that.
You can check about this on web. With wordpress you can develop your website effortlessly.
I hope this information is useful for you. Thanks
