Spacing being added between page text lines

All of a sudden the program is adding about 3/4 of a space between all the sentences. I have tried a number of ways to insert the text to no avail. Any ideas?

 

Please explain your problem with the help of screenshot and also share the link of your website.

 

I talked to a friend and he gave me a solution. Evidently, every time I pressed Enter to go to the next line, it was adding a paragraph space. My friend advised to press Shift / Enter. That worked.
