Be careful with this feature!
WARNING: This feature is available to you, but you can really make your webpages hideously ugly and unfriendly to visitors if you don’t know what you’re doing. Before you leap whole hog into this, why not contact WebSanity first?
Steps for adding extra space around a Block
Go to the Page with the Block to which you wish to give extra space.
Hover over Edit and press Edit This Page.
Click on the Block and choose Design.
The Set Block Styles panel will open.
Select the Spacing tab.
Enter the appropriate values in Margin.
If you’re going to be doing this a lot, save your work as a Preset by selecting Save this style as a new preset and typing a name for that style.
If you save your Margins as a Preset, you can simply select the Preset the next time from the Saved Presets menu at the top of the panel.
WARNING: As tempting as it might be, do not mess around with the other tabs and fields in the Set Block Styles panel unless (a) you really know what you’re doing, and (b) you’ve talked to WebSanity first. There are hidden dangers here and you can really mess things up!
