Coding in WordPress: How to Delete Specific Code Completely

[macfais]

I need something to change in my website format that is why I made a series of trial and error in entering some codes. I entered my code in the following:
1. Additional CSS of the wordpress theme
I entered my code and published it. Then, when I found that it was not working, I just simply deleted it using backspace and published it. Then gone.

2. Simple Custom CSS Plugin
I did the same in above number item no.1 when it did not work.

3. Text Source (of Wordpress sheet)
I did the same in above number item no.1 when it did not work.

I did a lot of trial and error and finally, I got it correctly but in the Additional CSS of the wordpress theme. However, when I inspect the element using chrome, I can still see my previously entered incorrect codes with cross-out markings though I deleted them already.

Is there something wrong with the way I deleted those that is why they are still there? Can someone teach me how to eliminate those?
Thank you.

Store all CSS code in style.css, this fill will be putted in your theme folder.

2. Simple Custom CSS Plugin
I did the same in above number item no.1 when it did not work.

What is CSS plugin? how will it work?

Thanks Marc. I got the answer. It is just in the inspect element that shows crossed-out.
