You can use layout boxes to position text and images freely on
your Web pages.
To move a layout box that you have created to a precise location,
you can use a grid.
To have the top-left corner of the layout box always snapped to
the grid when you move the frame, select Window > Preferences from the main menu, and then
select the Web Tools > Page Design > Layout category in the Preferences page.
Select the Snap layout box to grid check box.
To move a layout box, move the mouse pointer near the boundary
of the layout box until the cursor turns into a cross. Then drag the pointer
to the position you want to place the layout box. The layout box moves with
the top-left corner of the frame snapped to the grid.
To release the snap to grid function, clear the Snap
layout box to grid check box in the Preferences page.
To display the grid, click Window > Preferences on the menu bar, and then
select the Web Tools > Page Design > Layout category in the Preferences page.
Then, select the Show Grid check box. The grid will
be displayed on the page you are editing. To hide the grid, clear the Show
Grid check box.
