You can use the ruler guidelines to help line up and position items in any eCreator page.
To switch on the ruler guidelines, click on the Pencil within the page you are editing.
Click on Settings option.
Toggle Show Ruler Guidelines to on.
A ruler will display across the top and side of your eCreator page. Click on the ruler and drag a guideline to the desired position in your eCreator page. Double click on a guideline to remove it.
Once your guideline is in position, you can use it to line up items on your page.
Remember you can also snap items into position and move items in 1px increments. Position Panels in eCreator shows you how to do this.
