How to change the display of a blog item

Blog items are displayed in the Quark theme like this:

I usually start my blog entries with a level 1 heading, followed by the summary and by the blog entry content itself. This leads to this ugly form of display, as the level 1 heading is popping out.

I already read about tricks to "cut out" the summary, but I wondered, whether thre is a better way to just have the real summary in the blog item display.

Or how is a blog entry supposed to be written? Maybe I missed something obvious. ;)

Is there any specific use case where you need to duplicate title as a heading? Even in your screenshot you can see title is already there, so what's the point of this heading in the content?

If I do not enter a heading in the blog post itself, it looks like

The blog post itself does by default not render the title of the blog post, therefore the user does not know what the blog post is about, if he just has the link. That "forced" me to write down the title of the article.

Maybe the inventors of the Quark theme did not find it necessary to inform the reader about the title—but I had a lot of complaints when I first omitted the titles in the blog posts.

How do you solve this problem?

@pamtbaau:
I don’t understand this comment and the screenshot of the blog item. It seems you have edited the hero block in item.html.twig .
Again, when looking the the online Blog demo, the title (from the frontmatter) is clearly shown in both layouts.

You gave the right thought! I reactivated the plain Quark theme and still had no title or subtitle shown when displaying the blog item page, but this led to the fundamental problem: The display template was "Blog" and not "Item".

@pamtbaau:
I don’t think any sarcasm is justified here. I have the impression that the inventors of the Quark theme are highly experienced and know what they are doing. Also I don’t recall having seen a similar complaint before.

I didn't mean to be sarcastic in any way; if the impression arose, I am sorry. I just could not understand, why the basic information were not displayed, but now it is quite obvious, why they weren't.

@pamtbaau:
Maybe the inventor of your site… 😉

It is as alwas: error in front of the keyboard. 🙂

I will now try to find out why the graphics is not displayed, but at least this fundamental problem (which never has a problem as it seems) is now solved. Thank you!
