To accurately design a page, you can set the size of cells you add in a document. In the page you can also reposition cells.
1. Click the border of the layout cell to choose it.
2. To resize this layout cell, do one of the following:
• Within the Property inspector for the layout cell, type 510 into the fixed field to set the cell's width to 510 pixels, and after that click in the document to see the cell width modification.
Note: If you enter a pixel width which is larger than the width of the layout table or which causes the cell to overlap another cell in a layout table, Dreamweaver alerts you & adjusts the cell width to a valid width.
• On the right side of the layout cell, drag the middle resize handle to the right until the cell is the wanted width. Whereas you release the mouse, the cell's width is displayed into the column header area along the top of the layout table.
