![]() If your design calls for a images to have an aspect ratio that's different to the image's real dimensions, use the aspect-ratio property in CSS. Sometimes the dimensions of an image might be out of your control-if an image is added through a content management system, for example. With that rule in place, browsers will automatically scale down images to fit on the screen.Īdding a block-size value of auto means that the aspect-ratio of the images will remain constant. You can apply the same rule to other kinds of embedded content too, like videos and iframes. For example, xs= sizes a component to occupy the whole viewport width regardless of its size.You can use max-width instead of max-inline-size if you prefer, but remember it's good to get in the habit of thinking in terms of logical properties. The w3-half Class The width of the w3-half class is 1/2 of the parent element (style'width:50'). ![]() Basic gridĬolumn widths are integer values between 1 and 12 they apply at any breakpoint and indicate how many columns are occupied by the component.Ī value given to a breakpoint applies to all the other breakpoints wider than it (unless overridden, as you can read later in this page). W3.CSSs grid system is responsive, and the columns will re-arrange automatically depending on the screen size: The responsive classes above must be placed inside a w3-row class (or w3-row-padding class) to be fully responsive. The columns will re-arrange automatically depending on the screen size: On a big screen it might look better with the content organized in three columns, but on a small screen it might be better if the content were stacked on top of each other. ![]() A fluid grid's layout can use breakpoints to determine if the layout needs to change dramatically. Responsive Rows W3.CSS's grid system is responsive. Fluid gridsįluid grids use columns that scale and resize content. If you are new to or unfamiliar with flexbox, we encourage you to read this CSS-Tricks flexbox guide. The W3.CSS framework includes a grid system designed to be responsive to the screen size, rearranging columns as needed to render on. This means that it will always take up the minimum width required to present. ![]()
