Responsive site designer breakpoint6/3/2023 In addition, using device width, can prevent content from adapting on desktops or other desktops that allow the windows to be resized because the query is based on the actual device size, not the browser window. Min-width, is based on the size of the browser window, where as min-device-width, is based on the size of the screen. ![]() The difference is subtle, but very important. It’s also possible to create queries based on min-device-width or max-device-width, but this is strongly discouraged. Max-width rules are applied any time the viewport width is less than the value specified.įor example, max-width: 500px is matched when the viewport is 500 pixels or less. The media queries used most often for responsive web design are, min-width, and max-width. Above 800 pixels, not only do I have the orange text, butI also have the blue background. That means when the viewport is less than 500 pixels, no styles are applied but above 500 pixels my body color becomes orange. In fact, I recommend adding a catch all in your main CSS for image, embed, object and video elements, that sets this, just to be safe You can save yourself some headache, and prevent this from happening by setting a max width of 100%. So if you don’t specify a size and, say, for example the image is bigger than the container, it will overflow. Keep in mind, CSS does allow content to overflow it’s container. You should use relative units when specifying widths for elements to prevent them from accidentally overflowing the viewport. It’s important to make sure that the content fits within the viewport to prevent horizontal scrolling. This is why you should use relative positions instead of absolute positions such as width=100%. Large CSS widths or even absolute positions can result in elements that are either too big or don’t fit on the screen at all. ![]() Since CSS pixels vary so widely across different devices, you shouldn’t count on a specific viewport width for your content to render well. If not, it will leave the user having to scroll back and forth in order to view the entire image on any device that has a smaller viewport window. This is because fixed width images demand the viewport be at least that same size or greater for your content to render well. Relative widths are better suited for responsive design. They also scale the content rather than allowing it to reflow. Without initial-scale=1 some browsers will keep the page width constant when rotating to landscape mode. This allows the page to reflow content to match the screen sizes, whether rendered on a small mobile device or on the laptop.Īdding the attribute initial-scale=1 instructs the browsers to establish a one to one relationship between device independent pixels and CSS pixels.ĬSS pixels are what we’re used to working with most of the time, and really the only one I need to worry about. ![]() We need to use the meta viewport value width=device-width which instructs the page to match the screen’s width in device-independent pixels. We recently tapped into a consultant mindset on a complex engagement to foster collaboration and boost outcomes.Tag to the element of the page, we tell the browser that we know what we’re doing.
