An image map is a User Interface technique in which a user can click anywhere inside of an image, and the location of the click affects the outcome of the click. The idea is that clicking on different sections of the image creates different effects. For example, the image might be a map of the United States, and clicking within the borders of a particular state leads to a page about that state.

There are two kinds of image maps:. There are two parts to a client-side image map. The image with the usemap attribute, and the map itself. This means that the map element must have a unique name. The markup looks like this:. Unfortunately, image maps only work properly if you can be certain that the image will be display at its exact real size — they do not scale or adapt to responsive sizing.

Unless your browser is just exactly the right size, you should notice that the clickable areas do not line up with the shape pictures correctly. However, no browsers currently implement this feature. There is hope, however, if you really need scalable image maps.

With many small parts downloading at once your reader will be able to mentally fill in many of the blanks and so your map becomes usable in a shorter time. You can imagine what it would be like to have to work out the co-ordinates for your own shapes, so I advise you to use a specialised program for this. The code for my map above looked like this:.

See how it works? You start with a map element, and give the map a name. Then for each individual shape you use a nested area element, which includes the shapethe co-ordinatesthe urland the alt text of the hot spot. The code for the shapes are:. However, on computer screens, we measure y from the top of the screen down. The co-ordinates 50,23 mean 50 pixels from the left and 23 down. See the usemap tag? That follows the internal links syntax of using the name you had given your map and preceding it with a hash mark.

Also note that the main image can have an alt of its own and can even be active as a link.

The hot spots will always take precedence over the rest of the image, so you can have all the normal areas linked to something too. Also, your image might be un-readable to a reader surfing in colour mode. Think about accessibility. Haven't used it myself, but no doubt it's 'ace'.Similar to text links HTML also supports linking an image to a target resource. It will look like below in the browser and clicking on the image will take the user to the home page.

The above example is the simple and easy way of linking a small image to the target URL, but most of the cases the image will be bigger in size and there is a need to connect more than one link with the different sections of the same image.

This can be achieved in HTML with image maps feature and clicking on different sections of an image will open different links in a browser. Following are the two types of image maps possible in HTML:. Client side image maps Server side image maps We will discuss both topics in detail with example. Below is a simple image with px by px having three shapes — a rectangle, a circle and a polygon.

The image can be linked with three different pages on a site and each link is defined by a coordinates within the image. Clicking a particular shape of the image as defined by the coordinates will open a new page accordingly as shown below:.

The code for the above image should be something like below:. Usemap attribute is used to identify the name of the map along with tag. Ensure the uploaded image size is the same as you measured for defining the link areas. The coordinate starts with the upper left corner of the image with 0,0 and a question mark is added with the URL.

Oct 19, An image map is an image that has been divided into regions called hotspots ; when a user clicks a hotspot, an action occurs for example, a new file opens. Client-side image maps store the hypertext link information in the HTML document—not in a separate map file as server-side image maps do.

When a site visitor clicks a hotspot in the image, the associated URL is sent directly to the server. This makes client-side image maps faster than server-side image maps, because the server does not need to interpret where the visitor clicked.

Dreamweaver does not alter references to server-side image maps in existing documents; you can use both client-side image maps and server-side image maps in the same document. However, browsers that support both types of image maps give priority to client-side image maps. To include a server-side image map in a document, you must write the appropriate HTML code.

Note: To use hotspots in Dreamweaver, you have to be in design view. When you insert a client-side image map, you create a hotspot area and then define a link that opens when a user clicks the hotspot area. Note: You can create multiple hotspot areas, but they are part of the same image map. In the Map field, enter a unique name for the image map. If you are using multiple image maps in the same document, make sure each map has a unique name.

I have an existing image map in a responsive html layout. Images scale according to browser size, but the image coordinates are obviously fixed pixel sizes.

What options do I have to resize the image map coordinates? No major browsers understand percentage coordinates correctly, and all interpret percentage coordinates as pixel coordinates. There is a tutorial on how to do this. I ran across a solution that doesn't use image maps at all but rather anchor tags that are absolutely positioned over the image.

The only drawback would be that the hotspot would have to be rectangular, but the plus is that this solution doesn't rely on Javascript, just CSS. I put the image and the generated anchor tags in a relatively positioned div tag and everything worked perfectly on window resize and on my mobile phone. First of all, make sure your image is in a div that's relatively positioned. Then put the image inside this div, which means it'll take up all the space in the div. Finally, add absolutely positioned div's under the image, within the main div, and use percentages for top, left, width, and height to get the link hit areas the size and position you want.

I find it's easiest to give the div a black background color ideally with some alpha fading so you can see the linked content underneath when you're first working, and to use a code inspector in your browser to adjust the percentages in real time, so that you can get it just right. Here's the basic outline you can work with. By doing everything with percentages, you ensure the elements all stay the same relative size and position as the image scales. Use this code with your code inspector in Chrome or your browser of choice, and adjust the percentages you can use decimal percentages to be more exact until the boxes are just right.

Also choose a background-color of transparent when you're ready to use it since you want your hit areas to be invisible.

To create a larger image that connects links to different regions on the page, you need an image map.

In addition, include the usemap attribute to let the browser know that image map information should go with that image. The value of the usemap attribute is the name of your map. The map element uses the name attribute to identify the map.

The area element takes these attributes to define the specifics for each section of the map:. You can choose from rect rectanglecircleand poly a triangle or polygon. To determine image coordinates, you can use an image map editor such as Mapedit or a graphics editor such as PaintShop Photo Pro.
