You can adjust the spacing between blocks of text by using either paragraphs or line breaks.
In the example below, you can see the larger line break between the top two blocks of text and the smaller paragraph break between the bottom two blocks of text.
You can add paragraphs simply by hitting Enter on your keyboard. This will create a paragraph for the next block of text.
To insert a line break, hold down the Shift key and hit Enter as many times as needed to create the space required.
Please note: If you'd like to reformat existing text into paragraph format, you can do this by highlighting the section of text you wish to change and clicking Format > Formats > Blocks > Paragraphs in the content editor menu.
You can also edit paragraph and line-break tags within the source code, by using the <p> and <br> tags, as shown below.
