    You can add a link to any file on a server for people to download. There are multitude of applications that you use daily that run on a browser. Though they other programming languages, when the information is displayed on a browser, it is in HTML format.

    CSS USES

    CSS was designed to provide a posibility of modifying the layout and styling of the webpage. We are going to look in details on some of the uses of CSS.

    What is CSS used for:

    1. Layout the webpage.

    Using CSS, you can change the spacing and position of each specific item on a webpage. So, if you want to add spacing around an image? or do you want to add a fixed menu icon at the top? CSS is the language to use.

    You can add borders of different styles around any element. You can even place one element ontop of another item with z-index and absolute positioning. So, if you are interested in building unique and interesting layouts, use CSS.

    2. Setting colors of the text and background.

    CSS enables us to set the color of the text and background of each individual element found on a webpage. This is very useful since you can use and maintain your brand colors across the whole website.

    3. Choosing what to show on mobile or desktop

    With CSS you can set your webpage such that the content are displayed diffently depending on the gadget that your viewers are using i.e. mobile phone, tablet or a desktop. CSS helps adjust the webpage according to the screen size of the displays.

    4. Setting fonts types and style.

    Without CSS we would be stuck with the fonts already installed and supported by the browser. Thanks to CSS and designers who make web fonts, we can be able to use other cool and custom fonts available over the internet.

    5. Setting the sizes of all the components eg. images, text, video etc.

    Videos and images come it various size. With CSS we can fine tune the size and even make the image adjust its size according to the container holding it. We can also adjust text size so that the readers can be able to recognise the difference between a heading and a paragraph.
