And output

What I really try to do,

I mean, I want to use \parbox or \hlc, but I want the vertical distance to be the same as in the \empheq package, and the vertical distance from the right to the left \1em. I hope I could write my problem correctly.

• Sorry, this looks ugly – user31729 Dec 20 '17 at 20:16
• You're right. I think it's ugly. But I need to find a solution that matches the first picture. So I have to find a standard for the first picture and the second picture. What should I do? – Özgür Dec 20 '17 at 20:20
• You misunderstood me: The whole highlighting in the already highlighting box is not nice. Is this really necessary? – user31729 Dec 20 '17 at 20:21
• I did the answers in a single line. I need to find a solution to long answers too. Because I want to get a standard in all the documentation. Or you suggest a solution. What would you do if you were in your book? – Özgür Dec 20 '17 at 20:24
• I wouldn't use this yellow color. Like Christian I think that it looks rather ugly. – Ulrike Fischer Dec 20 '17 at 21:56
