This is a case for the CSS experts.

I'm not a CSS expert and my attempts at CCS have not worked.

You can enable the [</>] symbol for HTML code in the blog post, but the HTML code will be garbled and thus unusable.

I'm not an expert in CSS, but I used this code that the text in the blog, especially when responsive, is spaced from the margin. Is this what you meant?

<style>
.imBlogPostBody, #imBlogContent .imBreadcrumb, #imPgTitle, #imPgTitle a, .imPgTitle, .imPgTitle a {
margin-left: 20px;
margin-right: 20px;
margin-top: 12px;
}
</style>

My first attempt failed due to a typo, here is the 2nd attempt without a typo.

The CSS experts would still have to improve it to make it look good.

----- WebSite X5 -----

3 Sitemap

Blog: main page <-- click

Properties <-- Click

Advanced <-- click

Custom code:

Before the </HEAD> tag

<style>
.imBlogPostBody {
max-width: 640px !important;
}
</style>

New CSS-Code for centered text.

<style>
.imBlogPostBody {
margin: auto;
max-width: 640px !important;
}
</style>

On my website, I set the width specification to "720px" in the CSS code.

<style>
.imBlogPostBody {
margin: auto;
max-width: 720px !important;
}
</style>
