Questions: - To create the 3-column home page, you can copy the index.html page you just completed and rename it index3column.html. Then, you can copy the main.css file and rename it main3column.css - Modify the link element for the style sheet in the 3-column home page so it refers to the new style sheet. - Move the existing sidebar before the section in the HTML, and assign an id to this sidebar. Then, modify the CSS so it refers to the sidebar by this id. - Add another sidebar after the section, and add the content shown above to this sidebar. You'll find this content in the prepare.txt file in the text folder. Be sure to assign an id to this sidebar so you can use it to refer to the sidebar in the CSS. Then, format the sidebar as shown above. - Increase the width of the page to 1200 px . Then, set the widths and spacing for the section and two sidebars and the floating for the new sidebar so the page appears as shown above.

To address the task of creating a 3-column home page, follow these steps:

1. Copy and Rename Files:

   • Duplicate the existing index.html file and rename the copy to index_3_column.html.
   • Similarly, duplicate the main.css file and rename it to main_3_column.css.

2. Modify the Link Element:

   • Open index_3_column.html and locate the <link> element that references the CSS file.
   • Change the href attribute to point to main_3_column.css instead of the original CSS file.

3. Rearrange and Assign ID to Existing Sidebar:

   • In index_3_column.html, move the existing sidebar HTML code so that it appears before the <section> element.
   • Assign an id attribute to this sidebar, for example, id="left-sidebar".
   • Update main_3_column.css to style this sidebar using the new ID. For example:

     #left-sidebar {
       /* Add your styles here */
     }
     

4. Add a New Sidebar:

   • After the <section> element in index_3_column.html, add a new sidebar element.
   • Insert the content from prepare.txt into this new sidebar.
   • Assign an id to this new sidebar, such as id="right-sidebar".
   • In main_3_column.css, add styles for this new sidebar using the assigned ID:

     #right-sidebar {
       /* Add your styles here */
     }
     

5. Adjust Page Width and Layout:

   • Set the overall page width to 1200 pixels in main_3_column.css:

     body {
       width: 1200px;
       /* Other styles */
     }
     

   • Define the widths and spacing for the <section> and both sidebars to achieve the desired 3-column layout. Ensure that the new sidebar is floated appropriately:

     #left-sidebar, #right-sidebar, section {
       /* Define widths and spacing */
     }
     #right-sidebar {
       float: right;
       /* Additional styles */
     }
     

By following these steps, you will create a 3-column layout for the home page with the specified modifications.
