![]() ![]() ![]() As the containing div is then resized, the img SVG responds in an expected way. For example, if you were to wrap the img in a div, without specifying the height and width of the img, Chrome and Firefox will both assume the img has width: 100% the SVG is then stretched to fill the containing div, and its height is adjusted accordingly so that it preserves its aspect ratio. Normally, browsers are smart enough to determine the width and height of the SVG even if you don’t specify a width and height for the element. The contents of the SVG are then positioned inside the viewport depending on the value of the viewBox specified on the. When an SVG is embedded as an image in an tag, the height and width specified on the tag are used by the browser as a viewport to render the SVG into. We’ll be using the following SVG nautical logo in the demos. After removing the height and width, you can embed the SVG in one of several ways on the page. You should, however, leave the viewBox attribute present. When a fixed height and/or width is specified, the SVG is going to maintain that height/or width, thus restricting it from being fully responsive. In order to make an SVG fluid, the first logical thing to do is to remove the height and width attributes. In this article, we’re going to explore these techniques, going over when to use each one, in order to make SVGs fluid and/or adaptive. That said, there are certain “fixes” and hacks that we can use to get the expected behavior in all browsers. However, due to different browser implementations and inconsistencies, the web isn’t all ponies and rainbows, and making SVGs fluid isn’t quite that straightforward, because the way browsers determine the dimensions of an SVG when embedded in different ways isn’t consistent across all of them. ![]() The other commonly used techniques include embedding it as an image using the tag, embedding it using the tag, using an iframe, and as a CSS background image.Ĭonceptually, making an SVG scale as its container scales should be as simple as removing any fixed height and/or width, and specifying a viewBox attribute value. You may well have a site that is littered with images with fixed widths, here are a couple of solutions to fix those.Īlso here is a handy utility to see if your site is acting responsive for tablets and mobile devices.An SVG can be embedded on a web page in many ways one of which is embedding it inline in an HTML5 page using the tag. There are some new solutions being considered which serve different size images according to the user agent requesting them however these are not currently supported, this will be a step forward when it is ready as it will cut down on delivering full size images to be scaled on mobile devices. Instead of assigning an absolute width value via a HTML attribute in the tag of an image, assign the CSS rule max-width that targets the image as a percentage relative width value like so: img rule and also ensure the width attribute is not in the html. So here the image above on a Mobile device in either portrait or landscape orientation will not scale responsively in the viewport at the correct width for Apples iPhone its viewport is 320px portrait or 480px landscape, so images will display at their fixed size and the user on the mobile device, in the image example above they will have to scroll/swipe to see the full 590px of width – but the idea of responsive layout is to scale all the content into the viewable viewport without having to scroll width wise, it’s Ok to scroll (swipe) in a depth orientation so the height doesn’t really matter. The reason is because the images most probably have a fixed width which the web layout is honouring, so for example in your source code your image may have a tag like so: So you have got your web layout flexing and changing layout in a fluid or responsive web layout – but the images are not quite working they are being stubborn and not scaling and moving around like the text! ![]()
