Line length and Editing Labels

Hello, 
I'd like to edit 2 things in the blog view:

1. As you can see here, the line that devides articles is sometimes long, and sometimes short. It looks like it depends on the content of the post. 
 
 
That does not look nice. I want to have this consistent. A long line separating posts always. 
Ho do I do that? 

2. Under the post title (either front page view or blog view), shows the author name, date, view ...etc. 
I'm fine with these, I want them to appear. 
But I don't want the labels to show. 
For examples, I don't want the word "by" Before the author name. Or the word "published on" before the date. 
 
What should I edit?

Thanks.

Hello,

Please edit the file /media/templates/site/museum/css/custom.css and around line 350 find this:
Change it to this if you want to extend the line width:
Or change it to this if you want to get rid of this line:

Thank you. It worked.
What about question 2?

Hello,

You must create a template override for this. For example, for the blog page demo.hotjoomlatemplates.com/museum/index.php/blog you should copy the file /layouts/joomla/content/info_block/publish_date.php to the folder /templates/museum/html/layouts/joomla/content/info_block/publish_date.php (create all these folders because they don't exist).

Then, on the copied file, change this line: to this:
This is how you create template overrides for other parts of the info block (author.php, category.php, etc...).
