Use a text editor to open your catalog page. Refer to the examples in the textbook and update the table to add new first and last columns. Put a unit price in the last column and a radio button in the first column. Because XHTML organizes tables by rows, you will have to add new or tags to each table row.

For the radio buttons, you may first add empty column tags to all of the rows, then create and test content for just the first row, then add content to the remaining rows last. This approach can reduce the amount of rework. The radio button is a type of . Use the same name attribute on all of the buttons to show their connection. Assign something different to the value attribute of each button. Verify that you can select only one radio button at a time and validate the XHTML before you continue.

Embed the table in an XHTML form. To do so, add a

tag before the tag and add a tag after the tag. This way the form is contained entirely between the

and

tags. Inside the form, add a text box (another type of field) and a corresponding for the user's name. Add submit and reset action buttons (they are also types). Validate the XHMTL and test the form before you continue.

Apply a Style Sheet

Use a text editor to create an empty external CSS (call it style.css) and link it in the head of all three pages in your website. Now define styles in style.css for the paragraph (p), heading 1 (h1), form, and list item (li) element styles that affect a combination of the following:

font-family

font-size

color

text-align

Add a table style that specifies border-style, border-width, and border-color. Finally, create a class style .description that affects the font-style. In your catalog page, add the class="description" attribute to each table data element that contains a description.

Submit your pages to the W3C validator (http://validator.w3.org/) and correct all errors. Include screenshots of the results in your submission.

Also include the full XHTML code for each page, and screenshots of the pages as your web browser displays them. Summarize the steps you followed to create and perfect the website. Outline the difficulties you encountered and how you resolved them.
