How is the area tag in HTML used
The area tag in HTML is used to define a clickable area within an image map. It is used in conjunction with the map tag to create image maps, which allow certain regions of an image to be links. The area tag has attributes such as shape, coords, href, and target which define the shape and location of the clickable region, the destination URL of the link, and the target window or frame in which the link should open.
duno google it that might help 😺👍
Sure, here is a more detailed explanation of how the area tag in HTML is used:
The area tag is used within the map tag to define specific clickable areas on an image. It is commonly used with the img tag, where the image is divided into multiple regions, and each region can be made into a clickable link. The map tag specifies the name or ID of the image map, which is then referenced by the area tag(s).
Here is an example of how to use the area tag:
```html
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<img src="myimage.jpg" alt="My Image" usemap="#imagemap">
<map name="imagemap">
<area shape="rect" coords="0,0,100,100" href="page1.html" alt="Page 1">
<area shape="circle" coords="200,100,50" href="page2.html" alt="Page 2">
<area shape="polygon" coords="300,200,400,300,200,300" href="page3.html" alt="Page 3">
</map>
</body>
</html>
```
In this example, a rectangular region, a circular region, and a polygon region are defined using the area tag. The shape attribute determines the shape of the clickable region, which can be rect (rectangle), circle, or polygon. The coords attribute specifies the coordinates of the shape, where the values depend on the shape type. The href attribute defines the URL of the linked page, and the alt attribute provides alternative text for accessibility purposes.
When the user clicks on any of the defined areas, they will be redirected to the specified URL.

The area tag in HTML is used to define a clickable area within an image map. Here is how you can use the area tag with step-by-step instructions:
Step 1: Add the map attribute to the img tag
- Start by adding the map attribute to the img tag that you want to create clickable areas within. The value of the map attribute will be the id of the map element that contains the area tags.
Example: `<img src="image.jpg" alt="My Image" usemap="#myMap">`
Step 2: Create the map element
- Create a map element using the map tag.
- The map element should have an id attribute which matches the value of the map attribute added to the img tag.
Example: `<map id="myMap">`
Step 3: Add area tags within the map element
- Inside the map element, add area tags to define the clickable areas within the image.
- Each area tag should have attributes to define the shape, size, and coordinates of the clickable area, as well as the link or action associated with it.
Example:
```
<map id="myMap">
<area shape="rect" coords="0,0,100,100" href="page.html" alt="Clickable Area 1">
<area shape="circle" coords="150,150,50" href="page.html" alt="Clickable Area 2">
<area shape="polygon" coords="250,50,350,150,250,150" href="page.html" alt="Clickable Area 3">
</map>
```
Step 4: Adjust the shape, coordinates, and link/action as needed
- In each area tag, you can adjust the shape attribute to define the shape of the clickable area (e.g., rect for rectangle, circle for circle, polygon for custom shape).
- The coords attribute specifies the coordinates of the clickable area. The format of the coordinates will depend on the shape chosen.
- The href attribute specifies the link or action associated with the clickable area.
- You can also add additional attributes like alt to provide alternative text for accessibility purposes.
- Adjust these attributes as needed for each area tag.
That's it! By following these steps, you can use the area tag in HTML to create clickable areas within an image map.
The `<area>` tag in HTML is used in conjunction with the `<map>` tag to define clickable areas on an image. It is commonly used to create image maps, where different parts of an image can be linked to separate web pages or perform specific actions.
To use the `<area>` tag, you need to follow these steps:
1. Start by creating an `<img>` tag, which represents the image you want to create an image map for.
2. Inside the `<img>` tag, include the `usemap` attribute and assign it a unique name. This name will serve as a reference to the `<map>` tag.
```html
<img src="path/to/image.jpg" usemap="#imagemap">
```
3. After the `<img>` tag, create a `<map>` tag and assign it the same name as defined in the `usemap` attribute of the `<img>` tag.
```html
<map name="imagemap">
```
4. Inside the `<map>` tag, use one or more `<area>` tags to define the clickable areas on your image. Each `<area>` tag must include the following attributes:
- `shape`: Specifies the shape of the clickable area. It can be one of the following values: "rect" (rectangle), "circle", "poly" (polygon).
- `coords`: Defines the coordinates of the clickable area. The format of the coordinates depends on the shape being used.
- `href`: Specifies the URL of the linked web page.
- `alt`: Provides alternative text describing the area for accessibility purposes.
Example:
```html
<area shape="rect" coords="x1,y1,x2,y2" href="page1.html" alt="Link 1">
<area shape="circle" coords="x,y,r" href="page2.html" alt="Link 2">
<area shape="poly" coords="x1,y1,x2,y2,x3,y3,x4,y4" href="page3.html" alt="Link 3">
```
5. Close the `<map>` tag and make sure to close the `<img>` tag as well.
```html
</map>
```
By following these steps, you can create clickable areas on an image using the `<area>` tag in HTML.
