Avoid placing input items (such as fields, buttons, popups, lists, comboboxes, radios, and check boxes) on top of labels.
When input items are placed on top of labels, the user cannot use the mouse to give the items the focus or to interact with the item (for example, the user cannot click a check box to turn it on or off). The user must use the Tab key to move to the item and the keyboard to enter information in the item.
