The reason for this is because the device landscape is constantly changing therefore, todayвЂ™s popular device dimensions are always in flux. A working prototype of your webpage with actual content is needed to accurately identify this information.В It is important to note that your breakpoints should be determined by your content, not device-specific widths. The first step is to define the image dimensions and related breakpoint of each image which you plan to apply a responsive image solution to. Although the polyfill has some potentially downsides, they are outweighed by the benefits.Picturefill allows us to leverage the power of these attributes today.Utilize the srcset and sizes attributes to switch out aВ different source of the same image in order to respond to size and pixel density factors.Leverage automation when outputting your various image sizes.Consolidate image list to a more manageable length by eliminating values that are too close.Calculate pixel density factors and add these to your image list.Define image dimensions in relation to breakpoints.Breakpoints should be determined by your content and not device-specific widths.

By leveraging the tools made available by the вЂpictureвЂ™ specification, we now have a standardized responsive image solution that we can put into practice today. This is where the вЂpictureвЂ™ specificationВ comes in: a client-side solution for delivering alternate image data based on device capabilities. By leveraging a responsive image solution, we can ensure the best image is being loaded and bandwidth isnвЂ™t being wasted due to excessively large images. While there are a number of steps that can be taken to reduce this weight, perhaps one of the more important steps is to ensure that a responsive image solution is in place. It is safe to say that the web has quite the weight problem and images play a significant role. The average website weighs in at 2.16 megabytes and growing, with the majority of downloaded bytes beingВ attributable to images.
