CSS FLUID IMAGE DOWNLOADDepending on the screen size, the website sends a smaller or larger version of a visually sharp image so that the browser can then download the appropriately-sized version. What Are Responsive Images?Īs a critical component of flexible layouts, responsive images adjust the image size, orientation, and resolution based on the end-user’s device, enabling webpages to detect and respond to the screen conditions of visitors.Īs a rule, responsive images offer multiple options for an image. A mobile-first approach assumes that tablets, task-specific mobile apps, and smartphones are the primary tools for getting work done, addressing their requirements in the design. Responsive web design (RWD) contains webpages and apps that detect visitors’ screen size and orientation so that the browser can automatically adapt the display accordingly. Those classes also style images and optimize them for responsive behavior, i.e., scaling along with the image container when a browser window is resized. ![]() You can create components by adding Bootstrap classes to elements. The framework features global CSS settings a responsive grid system prebuilt components, e.g., carousels, forms, and navbars and optional JavaScript plugins, which speed up development by means of classes. If the amount of extra padding or border is not a %, then you'll probably need to look at using box-sizing: border-box, so your wrapper's dimensions aren't made any bigger by the box styling.Bootstrap is an open-source CSS framework, mostly for building responsive websites and mobile-first apps. If you require extra padding on your image container, you will need to take this into account when calculating the amount of bottom padding to apply in this fix. We also need to add position: absolute to the image, and position: relative to the wrapper, to ensure the padding is not added to the height of the image when the browser calculates the wrapper's height. (There's a couple more critical instructions below.) In the case of my grumpy cat picture, the original image dimensions are 360 x 240, so my padding-bottom on the wrapper should be 66.67% to simulate the correct height. It's not the perfect solution but you will then be able to apply this padding dynamically via JavaScript. Padding Bottom = (Image Height / Image Width) * 100%ĭon't know the ratio? Perhaps you should explore a way of returning the image dimensions to the frontend before the images are requested. ![]()
