I’m trying to make content management system for blog. How can I make a new page using my template for the page, with a press of button, to generate new post in new page? I’m using HTML, CSS, Javascript, local storage.

Still new to web development, I know how to create, read, update, delete content in the same page.

I tried this code in other stack post, but it doesn’t save on my local storage

var w = window.open("");
w.document.writeln("<the html you wanted to write>")

If u could share the link to learn, would be nice
