[WP] Spacing problem

[nEw_boY]

I cant actually define it properly...
I want to decrease space between two lines
eg.

This is WP window:

This is my NotePad++ text editor:

As you can see both the text are same but in wordpress gap between two lines is double compared to notepad++.
How can I decrease that thing globally ?
In Dashboard, blog everywhere I mean...

Single enter in wp takes much space and I want to make it something like 2nd image.
Any help will be appreciated.

Edit:
Google says something to do with style.css
Link to my style.css:

"line-height" needs some change but there are various settings 1, 1em, 24px...
I tried changing em but cant see any effect on my site.

Anyone ?

I have tried adding it under this line:

p { padding-bottom: 10px; line-height: 24px; }

It doesnt worked.
Do you know the concept of pixels, I mean what should be the ideal px ?

I tried 12px instead of 24 px in that line but still the same.
What next ?

Make a backup and "play" with it.. =)

That would be the last option, bro..
I gotta try if someone already have faced the same problem before since its there since I have installed WP raw, with default themes.

Edit: I have tried replacing every "line-height" attribute value to "normal" but it's still the same.
Help...

Right click on it > Inspect element (in chrome) and see the changes needed to be made.

Its simple when you want to jump to a new line just shift+enter
It will be in the immediate next line without any spacing.

Yes, it's working like said by hulkman.
Is there anyway to change that setting to default enter ?

I think there is no setting to change to default.

After tons of googling, I found that its annoying line break issue being discussed since a long time and still there isnt any specific shit to prevent it.

I`m still trying to get over it but cant...
When we press enter it uses <p> tag instead of <br> so its just totally wired.
