Quite simply, you only need to find the Element you want to use then Click, Drag and Drop it exactly where you want it.
While dragging an Element to a page, this blue guide line will tell you where the element will be placed when you drop it.
Either stack elements on top of each other, or, drag one element to the left or right of another.
Placing elements side by side will automatically create columns on the page that allot equal space to each element. You can adjust the space between these columns by using the narrow bar that appears between them by clicking and dragging it to the left or right.
The "X" in the upper right allows you to delete this element. Keep in mind though, once deleted, it can never come back.
The arrow in the upper left allows you to copy an element (to the same page or another page) to to move an element (to another page).
And clicking on the box between the "X" and the arrow, allows you to pick the element up and drag it around the page.
That's it! If you can edit a Word document you should be able to edit your own website, easy peasy!
