A horizontal rule may be inserted into the document using the Insert Rule command from the HTML Author menu, or the HRule button in the HTML Author toolbar. You will then see a dialogue box as shown below.
The rule can be inserted by clicking on the OK button. HTML Author will ensure that the rule is on a separate line. You can remove the rule by clicking it then pressing the delete key.
If you wish to influence the way in which the rule is displayed by the browser, you may alter some of the parameters in this dialogue box. The width of the rule may be defined as a percentage of the page width. The thickness of the rule may be defined by the size parameter. The rule displayed in the source document corresponds roughly to the size that would be obtained in Netscape. The alignment may be left up to the browser (None) or specified. The parameters shown in the diagram above give the following result:
To edit the properties of the rule, either double click on it with the mouse, or select it with a single click then click on the HRule button.
If the page layout of the document changes, the horizontal rules will no longer have the correct width in proportion to the page. To correct this, the Restore Layout command may be used from the HTML Author menu. This will also reposition any Left or Right aligned images.
