Hey there,
Regarding auto indentation the simplest way to achieve this without too much custom coding which I am afraid we cannot provide support for, is to do some of your own indentation by switching to the “text” tab of your editor and adding:
before every paragraph. Please keep in mind that when you switch back to the “visual” tab of the editor this change might be gone. So you would have to save the post while it’s on the “text” tab.
To achieve what you want with the site title then you could add the following to your child theme’s style.css:
.site-title{
display: none;
}
