    responsive design The Techniques and Guidelines Behind Responsive ImagesEvery web developer tries their best to keep up with the latest trends. They always try to support any new internet accessible devices. Previously, the support was only restricted to desktop and laptop but with the advent of smartphones and tablets all running Wi-Fi, their reach has extended. These advancements indicate that the developers have to work with the trends which can adapt naturally to every screen size. This is the speciality of responsive web design. But have you ever thought about how images are made responsive to every device platform? Reading this blog would answer your question. It will help you to understand the technique behind handling responsive images.

    If you think that you have to spend a lot of time after coding for creating images for responsive layout, then you are wrong. To make it easy for you, you can use a couple of techniques which will allow you to scale your website quickly.

    Techniques for making images responsive:

    Image styles and positions:

    One if the interesting way to present the images is to style it with CSS3 attributes. This will help you media stand out from amongst the other responsive content. If the images are adaptable they can be resized along with the layout of the page. When it comes to positioning the image, you must consider that the contents are falling on the page as well. As the user resizes their browser window, you must think about how the images will pile up. However, the position of the HTML elements will decide how they will be placed when the layout gets smaller in size. It is best to set up properties such as padded background or box-shadow for the img tag.

    CSS image resizing:

    Apart from making an image look pretty they should also be adaptable to the layout borders. If you leave any image without height and width settings, they will automatically fold over the page content. Here you can use responsive technique to define the width and height of all the images even while resizing them. The code to add maximum width properties to all the img elements on the stylesheet is – img {display: block; border: 0; max-width: 100}. However, the width becomes flexible with this code but the height remains static. To make the image heights flexible add height: auto; into the CSS properties.

    Retina images:

    One of the important aspects of responsive design is to deal with the retina devices. Any images may appear blurred on those devices which have dense pixel ratios. So how do you fix this? Do not worry at all. The best way is to make the size of the image double the normal size that is required. This ensures that the users using a retina screen will get to view all the advanced styles.

    WordPress users can look at WP retina 2X plugin.

    Important guidelines to be followed while working with responsive images:

    The use of vector-based images or font-icon: Vector-based images are the best alternatives to avoid the problem of pixel based images. Even you can create your own font icon simply with the icons you required. However, make sure that you use advanced enhancement of the icon fonts and utilise them in a manageable manner.

    Provide automated output for the image mark-up: The best solution is to use the picture fill solution to use in the mark-up for responsive images. However, whichever solution you choose, make sure that you centralise the mark-up to make modification easier in the future.

    Encourage users to upload the highest quality source: As prices for the high-density screen go up, they are more likely to show up in more devices and at larger sizes. Encouraging people to upload higher quality images means you are ready with resolutions required in the future. The biggest advantage is that keeping a track of these assets will help you redesign the site in the future easily.

    By using URL parameters, any image can be resized to any size: Image resizing with URL parameter should be able to take any information that recognises a source image as well as the measurement the image needs.

    Provide a way to override resized images for art direction requirements: One of the important uses of responsive images will be to deliver a different resolution of images based on the dimension that the image is used on the page at a specific viewport size. Often you will find that resizing an image is not sufficient. It may be that a smaller version of the same image cannot be identified.

    As a best practice, integrate image compression: If you intend to centralise image resizing as a service, you must integrate the best tools in image compression.

    Every responsive image should be flexible and should be modified easily when the solution for responsive images becomes apparent.
