Quick Reference
The <canvas> tag is a transparent container used to contain graphics on the page that are drawn using a scripting language like JavaScript. The JavaScript will refer to the <canvas> #id to write to it.
The two attributes that should be set are the width and height of your canvas. You should also place a line of text inside the <canvas> tag for those browsers without the ability to render it.
<canvas id="my_canvas" width="500" height="500">
Your browser does not support the canvas tag.
</canvas>Attributes
The following attributes can be used within the <canvas> tag.
| Attribute | Value | Description |
|---|---|---|
| height | pixels | Specifies the height of the canvas (default value is 150) |
| width | pixels | Specifies the width of the canvas (default value is 300) |
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.
