this property to enable or disable the appearance of scrollbars in a frame. The following options appear in this menu: Yes: Enables scrolling for a frame. When this option is selected, a scrollbar always appears in the frame, even if the content does not exceed the size of the frame. No: Disables scrolling for a frame. When this option is selected, a scrollbar never appears in the frame, even if the content exceeds the size of the frame. Auto: Enables scrolling for a frame only when the content exceeds the size of the frame. Default: Choosing Default excludes the Scroll property from appearing in code. Setting this option to Default doesn't set a value for the corresponding attribute, allowing each browser to use its default value, which is typically Auto. Setting the scrollbars for a frame is as simple as selecting a frame from the Frames panel and choosing an option from the Scroll menu. For our project, choose No for the Header frame, No for the Nav frame, and Auto for the Content frame. Frame Resize The next property you want to set is the frame No Resize property. Enabling this check box guarantees that users cannot grab the border (if it exists) and drag to resize the frame. Set this property by selecting each frame in the Frames panel and enabling the check box in the Properties Insppector. For our example, make sure that the box is enabled for all three frames. NOTE Earlier I mentioned that the ability to resize frames was one of the advantages to using frames. Although this is certainly the case, we'll prevent our users from resizing our Dorknozzle frame because the navigation items in the Nav frame are short and do not warrant allowing the user to resize.   Adjusting Borders and Border Color Another useful set of properties you can set are the Borders and Border color properties. Use the options in the Borders menu in the Properties Inspector to enable or disable borders within a frame in the browser. The following options are listed in this menu: Yes: Choose this option to show borders for a frame. No: Choose this option to hide borders for a frame. Default: Choosing the Default option doesn't set a value for the corresponding attribute, allowing each browser to use its default value, which is typically Yes. NOTE It's important to note that a border is hidden only when all frames that share the border have the Borders option set to No, or when the frameset's Borders property is set to No and the frames sharing the border have Borders set to Default.   The Border color picker allows you to set a border color for all of the frame's borders. This color applies to all borders that touch the frame, and overrides the specified border color of the frameset. For our example, set the Borders property to No for all frames and don't pick a color from the color picker. Margin Width and Height The last frames-based properties you can set in the Properties Inspector are the Margin Width and Margin Height options. These properties, represented by text boxes, function similar to the margin properties in the Page Properties dialog in that they allow you to specify how much of a margin width or height the frame should have. For our project, we set the top, left, bottom, and top margins in
