This plugin adds a spacer button to the WYSIWYG visual editor which allows you to add precise custom spacing between lines in your posts and pages. Note that you can also enter negative spacing to shift the following content upwards.
Via the Spacer Settings page, you can create an arsenal of additional spacers and sectional breaks to have at your disposal as you lay out your pages. The Spacers that you build can be added into your posts and pages with the spacer button in the WYSIWYG visual editor (see screenshots).
Spacer is also compatible with WordPress Multisite.
NEW IN VERSION 3.0
