Introduction to Area Tag in HTML
In this article, we will learn about Area Tag in HTML. Area Tag is used to defining a hotspot in an image map and associates or link with a hypertext reference so that it allows a user clickable on the web page. It helps in linking to the different pages while a map portion is clicked. And a tag becomes useful when there is a need for multiple links on the image.
The basic Syntax is given below:
<area alt=”text” class=” “coords = “ “ shape “ ”/> ;
Here alt is used for alternate text if an image is not rendered.
- class: Defines a class name for an element.
- coords: Has a set of values for the shapes.
With an image map, the Syntax is:
;<img usemap="# name" src="path loacation">
<map name=" name">
<area shape="shapeName1" coords="x,y coordinates" href="html linkPath">
<area shape="shapeName2" coords=" x,y coordinates " href="htmllinkPath">
Explanation: This is an empty tag with no closing tags whereas in the case of XHTML it is declared as <area/>. And this area tag is always embedded with <map> tag (included in the map container), gives the coordinates values of the specific image. And also an overlapping takes place inactive areas, it is resolved by given priority to the area that is higher is activated. So, the following portion covers how to use area tag with an example, as well as Brower compatibility and supported attributes by them.
How does Area Tag work in HTML?
Here is the process to make through, Initially image in the image map.
1. To insert an image to the page, we are supposed to use an image tag which is given below:
<img src="edu.jpg" alt="EDUCBA logo"> // image from the saved folder. Also, we can get from the web URL directly and map with <map> tag.
It comes with two attributes src: Source and alt- text describing the image content.
2. Secondly, opening the map element with the attribute #map. This image tag comes with a use map followed by the ‘#’ symbol (use map =” #map”). Mapname should be the same name as the usemap.
How to create an image map? by using use map and name attributes together to have images and maps together. The browser recognizes the area of the shape when the mouse cursor over the screen becomes a pointer(hand symbol).
3. To declare the areas that to be used to map.
< area shape=”rect” cords=…….href=”” alt =””>
href comes with alt attribute by default.
In general HTML tags has one or more attributes that help in how to show the browser visually pleasant. There are three varieties of attributes are used namely global, event handling, element-specific attributes. The area tag contributes tag-specific attributes, as well as a description of them which are listed below and the HTML 5 has some new attributes.
1. Tag-Specific Attributes
|Name of Attributes||Description||Example|
|alt||Defines an alternate text in the specified area which improves accessibility.||<area alt=”hello” shape=”circle” coords=”40, 50, 10″>|
|href||Defines the hyper reference means a link to the next page points/ URL of a Page. It changes an area into a hyperlink.||<area href=”doc.html” alt=document” shape=”circle” coords=”30, 30, 20″>|
|shape||Defines the different shapes to be done on the image.||<area href=”doc1.html” alt=”First doc” shape=”circle” coords=”40, 40, 20″>
<area href=”doc2.html” alt=”Second doc” shape=”rect” coords=”11, 82, 92, 160″>
<area href=”doc3.html” alt=”Third doc” shape=”poly” coords=”11, 170, 12, 110, 15, 197″>
|coords||Gives the specific values appropriate to the region in the image. The Coords are specified as follows :
Default : no cords required.
Rect : left,top,right, bottom
Circle : x , y ,radius
Poly: x1,y1, x2,y2,x3,y3…
|<area href=”doc.html” alt=document” shape=”circle” coords=”30, 30, 20″>|
|target||Specifies where to open the link page or I can say the end target page.||<area href=” new.html” target=” _blank” alt=” First” shape=”rect” ords=”10, 40, 60, 170”>|
|Nohref||Defines that absence of href. Means area doesn’t have link to next page||<area nohref shape=” rect” ords=”10, 40, 60, 170”>|
|type||Specifies the content type (MIME)||<area href=”pic.jpg” type=”im/jpeg” alt=”Authors edition”>|
|hreflang||Specifies language-type||<area hreflang=”es-ES” href=”esd.html” alt=”Second doc (spanish version)” shape=”rect” coords=”10, 60, 90, 150″>|
2. Standard Attributes
The description of these attributes has already been discussed in the previous article.
- Access key
- tab index
3. Global Attributes
- onmouse down
- onmouse up
- onmouse over
- onmouse move
- onmouse out
- on focus
- on blur
- onkey press
- onkey down
- onkey up.
Examples to Implement Area tag in HTML
Below are the examples to implement area tag in HTML:
In the below example I have created a jpg image diary.jpg. When u executed the code the hand tool moves over the image at the specified cords when you have a click on it, it directs to the page rr.html.
<img usemap="#Diary" src="diary.jpg">
<area shape="rect" coords="94,91,189,193" href="rr.html">
<body> Online tutorial Class</body>
<img src="edu.jpg" alt="EDUCBA logo" width="412" height="82" usemap="#ccmap" class="logo"/>
<area shape="rect" coords="89,9,294,50" href="sha.html" alt="EDUCBA">
<area shape="rect" coords="297,7,407,54" href="rr.html" alt="Welcome">
<body> Online tutorial Class</body>
<body> Welcome to the Page</body>
In the Output below shows the logo of EDUCBA, Clicking the word BA directs to the page Hello page.
<img src="new.png" alt="usemap" border="0" usemap="#Protocols"/>
Explanation to the above program: In this example, we have created an image map using the image file called new.png which has three clickable areas declared within it using the <area> tag. The first clickable area is a polygonal shape that links to the SNMP page called www.managengine.com The second clickable area is a rectangle shape that links to the FTP page called www.searchnetworking.com and finally, the last clickable area is a circle which links to HTTP page called www.webopedia.com.
Therefore, we have seen how the area tag used in active areas in switching to the pages with a piece of brief information also explains how to use the <area> tag in clickable areas with syntax and demo examples.
