You can use external CSS libraries to help code you website faster. CSS Libraries are CSS code preprogrammed. Once you know the structure of CSS code then you just name your elements or “tags” after the libraries structure. Many of the CSS libraries that are available help you create responsive websites.
Programming CSS Code *
In an earlier lesson we programmed a mini website with CSS. We learned that first we need to set up the id’s and classes then we style them with CSS commands. We also learned that browsers have their own set of CSS in them. There is something called a style-sheet reset. What the reset does is takes common things that browsers have programmed in them and sets them back to zero. Then you just enter your CSS commands to control what you want the webpage to do.
HTML Structure with CSS *
You have to first set up your elements in HTML. Then you style them with CSS. Everything of course starts with the HTML. If you do not have HTML elements in place you cannot style a webpage. You can have HTML without CSS but not the other way around.
Advantages To Using CSS Libraries *
There are several advantages to using CSS Libraries. I will list them here in a bullet list.
- Code Faster.
- Responsive for all devices.
- You can use them instantly.
- Preinstalled icons you can use on the fly.
- A lot of support.
How to Use A CSS Library *
In order to use a CSS library you have to bring it into the webpage you are working on. In a earlier lesson we did this by calling in an external file. Bringing in a CSS library is no different. You can use a CSS library in 2 ways.
- Download it and store it on your computer or server.
- Call the CSS Library in from the internet.
Examples To Call In CSS Library *
In your head tag you want to create a link element. Set the relationship to stylesheet and the type to text/css. This example calls in a stylesheet that is located on your local computer or server.
<link rel="stylesheet" type="text/css" href="style.css" />
If you are calling in an external library from another server it would look something like this in your head tag.
<link rel="stylesheet" type="text/css" href="http://website.com/style.css" />
List of CSS Libraries You can Use Right Now *
You can begin using any one of the CSS libraries listed below in your projects. Remember you just have to add the class or id’s to your elements to make them work. Some of them are for entire websites and some are just for features in a website. I will separate them for you accordingly.

Bootstrap is one of my favorites. It is easily used in websites.
