When you press Enter while writing something in a knowledge base article, you may find that it adds to much space in between text lines.
What happens actually is that when you hit Enter, a new paragraph gets created. If you want to start typing from a new line without creating a new paragraph, press Shift+Enter combination instead of just Enter. The behavior is expectable and it is the same as in Microsoft Word.
If you would like to make spaces between text paragraphs, you can do this by tiny change in the CSS styles.
Simply go to Customization > Manage Templates and add the following code to the CSS > User Styles section:
You can adjust the space by changing "5px" to other values (by default it equals "17px").
If you do not have a custom theme yet, please create it prior to inserting the aforementioned code.
