Quick Reference
The <col> tag specifies column properties for each column within a colgroup tag. This is useful for applying styles to entire columns. In the following, we have three columns defined with styles applied inline, and then the row follows with the three columns of data.
<table>
<colgroup span = "3">
<col style="background-color: red;" />
<col style="background-color: green;" />
<col style="background-color: blue;" />
</colgroup>
<tr>
<td>col 1</td>
<td>col 2</td>
<td>col 3</td>
</tr>
<tr>
<td>col 1</td>
<td>col 2</td>
<td>col 3</td>
</tr>
</table>Attributes
The following attributes can be used within the <col> tag.
| Attribute | Value | Description |
|---|---|---|
| span | number | Specifies the number of columns the element should span |
HTML Notes:
- In our HTML section the term “tag” and “element” are often used interchangeably to refer to both the tag used to create a page element and the element created by the tag (<p> tag = <p> element = paragraph on the page)
- HTML5 is not case sensitive; so <P> is the same as <p>, <H1> is the same as <h1>
- Global attributes can be used with all HTML tags and are therefore not mentioned on every tag page
- To write clean, readable HTML code, it is best to use indentation whereas elements within elements are indented (tabbed or spaces) to create something that looks like a project outline
- The browser will automatically remove any extra spaces and lines in your HTML code when the page is displayed
- Double quotes or single quotes can be used around HTML attribute values, but when the attribute value itself contains one form of quote, it will be necessary to use the other around the attribute
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
