Quick Reference
There are three “shapes” that can be used to define the clickable areas within an ImageMap.
| Shape | Description | Example |
|---|---|---|
| rect | Defines a rectangular region | The first two numbers are the top left point of the rectangle and the last two numbers are the bottom right point of the rectangle |
| circle | Defines a circular region | The first two numbers represent the location of the center of the circle; the third number is the radius of the circle. |
| poly | Defines a polygonal region | The poly shape uses many sets of x/y coordinates to create any kind of shape by connecting all the points with straight lines |
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.

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 (
ptag =pelement = paragraph on the page) - HTML5 is not case sensitive; so
Pis the same asp,H1is the same ash1 - 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
