CSS3 is used to design websites
CSS3 stands for ‘Cascading Style Sheet’. Style sheets are used for the design of a website – and this is completely independent of the page structure, which is described in HTML. CSS3 can centrally control all the elements of a website – the size of the headers, the distance between sections of texts, the font and even the background images can be set or changed if necessary. In addition, they are used to expand the content for various output media, such as computers, tablets, smartphones or printers, so that it is clearly readable.
CSS3 takes over as standard for style sheets from CSS3
The internet is constantly changing, and technologies that are based on it are subject to change. CSS 2.1 was the standard for style sheets for a long type, and now CSS3 has now almost replaced it. There is a transition taking place at the moment: many CSS3 features are supported by modern browsers, yet some still respond to the old standard. CSS3 offers many interesting features that help web designers easily control the visual appearance of a website. For example, graphic effects such as rounded corners or colour highlighted columns can be created without too much hassle – before, it would take a web designer a long time.
Other practical innovations in CSS3 are media queries, which are media specific style sheets. Thanks to media queries, the presentation of a website on the user’s monitor can be cropped – which is especially useful for websites on smartphones. With the help of media queries, the resolution, the orientation of the device’s screen and the extent of the device as well as browser window can be determined.
In addition, not only the look of the website and the presentation on various end devices can be designed differently with CSS3 – CSS3 can also be used for the visualization of music titles.
