The only difference is the number of columns specified in the columns property. Here is a GIF animation that shows a page layout with two columns change to a single column on window resize: ( source )ĭo you need a multi-column page layout? In the same way we can define threeColumns and fourColumns classes for three-column and four-column layout, respectively. Resize the window and watch how the text flows, the two columns change to a single column, and how the GIF image resizes. height: auto - disable fixed height in embedded images so that resizing can be done with the proper aspect ratio.max-width: 100% - automatically shrink embedded images to the width of the column.We also want images to automatically shrink if they do not fit into the screen or window width: Note that this currently is not supported by Firefox. column-span: all - interrupt the column flow at h2 headings.Let's use CSS to tell the browser to start a new column layout at h2 headings: Now, at some point it is desirable to interrupt the flow of two columns. That is why we specify browser specific properties (such as -moz-column-gap) along the official properties (such as column-gap). The columns and column-* properties are fairly new. column-rule: 1px solid #e2e2e2 - the vertical rule between columns is a solid light gray line.column-gap: 4em - the gap between the columns is 4 ems.If the width of the screen or window is less than 300 pixels, a single column is used. columns: 2 300px - this tells the browser to use maximum two columns, with a minimum width of 300 pixels.The CSS for two-column layout looks as follows: Content in columns flow properly on a page per page basis when printing out a long text with a two-column layout.įirst, let's enclose text in a div tag that has a class for the two-column layout. It will degrade gracefully to a single column on older browsers. This can be achieved with some CSS modern browsers can interpret. On a mobile phone you will see just one column. In this blog we cover one aspect of responsive web design: How to create the fluid, proportion-based grids, or a multi-column page layout that changes depending on the device used.
