Technologies used for Responsive Web Technology:

The two main factors to be followed:

  • Bandwidth:

    High-resolution images are used for greater clarity in the retina display and in desktops. But, in mobile networks, it will consume more bandwidth and increase website loading time. Therefore, you need to replace that high-resolution image with a low-resolution image.

  • Art direction:

    Images deliver a lot of detail will not be so clear in a smaller viewport. So we need an alternative method using CSS or some other technique.


The current technologies are as follows:

  • An easy and simple way in CSS is present-

    img { max-width: 100%; height: auto; }

    This will enhance the image to its screen size but will neither save the bandwidth nor the art direction.

  • Adaptive images:

    This is a server-side technique. It requires the .htaccess file and script files to be added to the website. This adaptive image technique will detect the screen size of the user’s device and automatically re-scale the image corresponding to the device.

  • HiSRC:

    HiSRC is a simple JQuery plug-in that checks the user current internet connection. If the connection is slow, the low-resolution image is loaded and then again checks the connection and if the connection is high the high-quality image will be loaded. The HiSrc is one of the useful plug-ins for determining the established user connection.

  • Srcset attribute:

    This attribute accepts the image’s source path. It also supports the pixel density descriptors, such as 1x, 1.5x, and 2x.

  • Media attribute:

    This attribute is like the @media selector in CSS. It accepts all valid media queries.

    Example:  <picture>
    <source srcset=”mdn-logo-wide.png” media=”(min-width: 600px)”>
    <img src=”mdn-logo-narrow.png” alt=”MDN”>

  • Sizes attribute:

    This attribute accepts the width descriptors (e.g. 80vw). It denotes the proportion of an image to fill the view port.

  • Type attribute:

    This attribute accepts the different types of image file formats.

    Example: <picture>

    <source srcset=”mdn-logo.svg” type=”image/svg+xml”>

    <img src=”mdn-logo.png” alt=”MDN”>
