How to create my own blog post template ?

Hi there,

how does this 'template' differ from the standard post template?
And are you wanting several custom templates to choose from ?

It just automatically gives me a setting that I want.
Like, I don't have to change it again to "No Sidebar", Disable Comment, etc
Also the font size, color, and typography if possible.

Is it possible to create one ?

Thanks

OK.
So to begin Customizer > Layout > Sidebars you can disable the sidebar for all posts:

For other options that you may use Disable Elements for, you can do them globally using a Layout Element:

For comments you can disable them across your site:

For typography and colors - are these to be different to the other pages on your site ?

Hi there,

I think I was explain it in the wrong way. What I want is to create a blog post style like this https://prnt.sc/mrle3ff30lQp

It has tab of content in the left. And the tab of content will be above the content if open with mobile device

I just want to have freedom to design my blog post layout. I don't like the blog post default style.

You could use a Block Element - Content:

But to be honest that example site isn't going to be easy to replicate using any method, and will take some custom development.
