<map title="mymap">

4

  <space form="rect" coords="0, 0, 50, 50" href="page1.html">

5

  <space form="rect" coords="50, 0, 100, 50" href="page2.html">

6

  <space form="rect" coords="0, 50, 50, 100" href="page3.html">

7

  <space form="rect" coords="50, 50, 100, 100" href="page4.html">

</map>

On this instance, we have now a picture with a map named mymap. The map has 4 areas outlined with the <space> component, every with a unique form, coordinates, and URL.

Consequence

Right here’s how we’d put a picture with 4 areas to make use of:

Attributes

The <space> tag helps International Attributes in HTML. International Attributes are frequent to all HTML components and can be utilized on all of them (although they might not have a lot impact on some).

• form: could be set to circle, default, poly, or rect, relying on the form of the clickable space.
• coords: defines the coordinates of the clickable space (extra particulars under).
• href: specifies the URL that the clickable space ought to hyperlink to.

Different attributes embody alt, goal, obtain, ping, rel, and referrerpolicy.

How Does the coords Attribute Work?

The coords attribute is the place we outline the coordinates of the form attribute. 

For instance, if the form is rect (a rectangle) as in our demo above, you’ll outline the top-left and bottom-right coordinates of the rectangle. A rectangle with the coordinates 0,0,50,50 would have its top-left nook positioned at 0,0 and its bottom-right nook at 50,50:

In order that’s rectangles, however for different shapes the coords attributes accepts totally different values:

• circle: the accepted worth is x,y,radius the place x,y are the coordinates of the circle heart, adopted by the radius.
• poly: the accepted worth is x1,y1,x2,y2,..,xn,yn the place the pairs dictate the factors alongside the sides of the polygon. The primary and final coordinate pairs are anticipated to be the identical, but when that’s not the case the browser will add a final worth to shut the form.

Content material

The <space> component is commonly used along side the <img> component, nevertheless it will also be used with different components corresponding to <object> and <canvas>. The component can be utilized when phrasing content material is predicted, however provided that there’s a map component ancestor.
