[FEATURE] RTL Support Request and wider page style

Describe the feature you want 描述你的功能需求

Hello
First, I hope this repo continues and doesn't get canceled like many other repos on GitHub.
I had a request to add right-to-left support for posts and the site template for Persian (Fa) and Arabic (Ar) languages.
And also wider pages the width of the page.
On blog pages, unfortunately, there is a box to the left of the image, which I hope can be removed, and the length of the posts and the width of the page can be increased like the second picture.
I'll add two images below to better explain what I mean.
and the site logo can be shifted to the left side a little more like the third photo.

I think these changes can make a website like a pro.

Thank you all.
