About HTML Preprocessors

HTML preprocessors can make writing HTML more powerful or convenient. For instance, Markdown is designed to be easier to write and read for text documents and you could write a loop in Pug.

Adding Classes

In CodePen, whatever you write in the HTML editor is what goes within the <body> tags in a basic HTML5 template. So you don't have access to higher-up elements like the <html> tag. If you want to add classes there that can affect the whole document, this is the place to do it.

About the <head>

In CodePen, whatever you write in the HTML editor is what goes within the <body> tags in a basic HTML5 template. If you need things in the <head> of the document, put that code here.

About CSS Preprocessors

CSS preprocessors help make authoring CSS easier. All of them offer things like variables and mixins to provide convenient abstractions.

CSS Base

About CSS Base

It's a common practice to apply CSS to a page that styles elements such that they are consistent across all browsers. We offer two of the most popular choices: normalize.css and a reset. Or, choose Neither and nothing will be applied.

     

Vendor Prefixing

About Vendor Prefixing

To get the best cross-browser support, it is a common practice to apply vendor prefixes to CSS properties and values that require them to work. For instance -webkit- or -moz-.

We offer two popular choices: Autoprefixer (which processes your CSS server-side) and -prefix-free (which applies prefixes via a script, client-side).

     

Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

Powered by Algolia
About External Resources

You can apply CSS to your Pen from any stylesheet on the web. Just put a URL to it here and we'll apply it, in the order you have them, before the CSS in the Pen itself.

If the stylesheet you link to has the file extension of a preprocessor, we'll attempt to process it before applying.

You can also link to another Pen here, and we'll pull the CSS from that Pen and include it. If it's using a matching preprocessor, we'll combine the code before preprocessing, so you can use the linked Pen as a true dependency.

About JavaScript Preprocessors

JavaScript preprocessors can help make authoring JavaScript easier and more convenient. For instance, CoffeeScript can help prevent easy-to-make mistakes and offer a cleaner syntax and Babel can bring ECMAScript 6 features to browsers that only support ECMAScript 5.

Learn more · Versions

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

About External Resources

You can apply a script from anywhere on the web to your Pen. Just put a URL to it here and we'll add it, in the order you have them, before the JavaScript in the Pen itself.

Use npm Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import. We'll also process your JavaScript with Babel.

              <!--za kreiranje elemenata u našem primjeru smo uglavnom koristili div elemente, div element je block element što znaći da će svaki novi div preći u novi red, ako želimo da se nižu jedan iza drugoga moramo napisati display:inline-block;. nakon kreiranja elementa, dodjeljujemo mu klasu kako bih te elemente mogli dohvatiti u css-u i kasnije u java scripti. Element možemo dohvatiti i pomoću ID-a ali zapamtite da je ID jedinstven i nesmijemo imati 2 elementa s istim ID-em.-->

        <li>Inline - elementi se slažu jedan pored drugoga ako u redu ima mjesta za njih</li>
        <li>Block - svaki element koji ima svojstvo block kreće od novog reda i možemo mu postaviti visinu i širinu</li>
        <li>Table - ovim svojstvom kažemo da nam se element ponaša kao tablica</li>
        <li>Flex - kreiramo flexbox što smo već koristili u prvom i drugom primjeru. Tim svojstvom napravimo dužinu elementa relativnu drugim elementima</li>

    <h3>Position</h3>
    <p>Css svojstvo određuje tip metode pozicioniranja elemenata. Postoje 4 metode pozicioniranja. Nakon što smo odredili tip/metodu element možemo pozicionirati svojstvima top,bottom,left i right, ali ta svojstva različito djeluju s obzirom na tip poziciniranja.</p>
    <ul>
      <li>static - početna vrijednost svakog elementa</li>
      <li>relative - normalna pozicija elementa</li>
