But use it correctly - to identify the intrinsic height of the image file, not to specify the desired layout size. The responsive CSS example below shows the procedure for initiating a certain CSS file with respect to the page width. Responsive Web Design is an approach to web-page creation that makes use of flexible layouts, flexible images, and cascading style sheet (CSS) media queries. It doesnt shrink or grow according to screen size. When the user resizes the window on a laptop or desktop or changes the orientation of the phone or tablet, the app should respond by rearranging the UI accordingly. This is necessary when the same app can run on a variety of devices. So yes, use the width (and the height) attribute. Fluid sizing Fixed: This option keeps the width of the element the same across all viewports. A responsive app lays out its UI according to the size and shape of the screen.
However, if both are specified, the browser can do some math to figure it out: display_height = img_height × ( display_width ÷ img_width )ĭoing this will stop that annoying jump that happens when a freshly loaded images suddenly takes up space in the document and shoves all the content down, causing the user to lose their place on the page.

Until the browser is able to download the entire image, and check the file header for its size, how does the browser know how much height to allot for the image? In the absence of a width and height attribute, it doesn’t. Consider the example above - the CSS width is set to 100% and the height is set to auto. It is not essential, but it will help the browser render your page faster and more cleanly, especially when combined with the height element.

Finally, we set the height of the wrapper to 0 and add padding-bottom based on the aspect ratio: padding-bottom width / height.
