HTML and CSS Reference
In-Depth Information
Now that you've seen how columns can be referenced through the use of column
groups, you'll create a column group for the programming table. You'll mark the fi rst col-
umn containing the broadcast times for the different KPAF programs using a col element
with the class name fi rstCol , and mark the remaining seven columns containing the daily
program listings with a col element spanning seven columns and identifi ed with the
class name dayCols . These groupings will allow you to format the two sets of columns in
different ways later on in the next session.
To mark the column groups:
1. Return to the schedule.htm file in your text editor.
2. Directly below the caption element, insert the following colgroup element, as
shown in Figure 5-20:
<col class=”firstCol” />
<col class=”dayCols” span=”7” />

3. Save your changes to the file.
4. Creating row groups and column groups defines the table's structure but should
not alter its appearance. To confirm that the row and column groups have not
modified the table's appearance, refresh the schedule.htm file in your browser.
Verify that the table layout is the same as that shown earlier in Figure 5-18.
