HTML

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.

CSS

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 URLs added here will be added as <link>s in order, and before the CSS in the editor. You can use the CSS from another Pen by using its URL and the proper URL extension.

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.

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

JavaScript

About JavaScript Preprocessors

JavaScript preprocessors can help make authoring JavaScript easier and more convenient.

Learn more · Versions

Babel includes JSX processing.

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.

Powered by Algolia
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.

If the script 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 JavaScript 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.

Packages

Add Packages

Search for and use JavaScript packages from npm here. By selecting a package, an import statement will be added to the top of the JavaScript editor for this package.

Powered by Algolia
About Packages

Using packages here is powered by esm.sh, which makes packages from npm not only available on a CDN, but prepares them for native JavaScript ESM usage.

All packages are different, so refer to their docs for how they work.

If you're using React / ReactDOM, make sure to turn on Babel for the JSX processing.

Behavior

Auto Save

If active, Pens will autosave every 30 seconds after being saved once.

Auto-Updating Preview

If enabled, the preview panel updates automatically as you code. If disabled, use the "Run" button to update.

Format on Save

If enabled, your code will be formatted when you actively save your Pen. Note: your code becomes un-folded during formatting.

      <h2> Here's a time line of Dr. Borlaug's life: </h2>
      <br></br>
      <ul>
        <li> <strong> 1914 </strong> - Born in Cresco, Iowa </li>
        <br></br>
        <li> <strong> 1933 </strong> - Leaves his family's farm to attend the University of Minnesota, thanks to a Depression era program known as the "National Youth Administration" </li>
        <br></br>
        <li> <strong> 1935 </strong> - Has to stop school and save up more money. Works in the Civilian Conservation Corps, helping starving Americans. "I saw how food changed them", he said. "All of this left scars on me." </li>
        <br></br>
        <li> <strong> 1937 </strong> - Finishes university and takes a job in the US Forestry Service </li>
        <br></br>
        <li> <strong> 1938 </strong> - Marries wife of 69 years Margret Gibson. Gets laid off due to budget cuts. Inspired by Elvin Charles Stakman, he returns to school study under Stakman, who teaches him about breeding pest-resistent plants. </li>
        <br></br>
        <li> <strong> 1941 </strong> - Tries to enroll in the military after the Pearl Harbor attack, but is rejected. Instead, the military asked his lab to work on waterproof glue, DDT to control malaria, disinfectants, and other applied science. </li>
        <br></br>
        <li> <strong> 1942 </strong> - Receives a Ph.D. in Genetics and Plant Pathology </li>
        <br></br>
        <li> <strong> 1944 </strong> - Rejects a 100% salary increase from Dupont, leaves behind his pregnant wife, and flies to Mexico to head a new plant pathology program. Over the next 16 years, his team breeds 6,000 different strains of disease resistent
          wheat - including different varieties for each major climate on Earth. </li>
        <br></br>
        <li> <strong> 1945 </strong>- Discovers a way to grown wheat twice each season, doubling wheat yields 1953 - crosses a short, sturdy dwarf breed of wheat with a high-yeidling American breed, creating a strain that responds well to fertilizer. It goes
          on to provide 95% of Mexico's wheat. </li>
        <br></br>
        <li> <strong> 1962 </strong> - Visits Delhi and brings his high-yielding strains of wheat to the Indian subcontinent in time to help mitigate mass starvation due to a rapidly expanding population </li>
        <br></br>
        <li> <strong> 1970 </strong> - receives the Nobel Peace Prize </li>
        <br></br>
        <li> <strong> 1983 </strong> - helps seven African countries dramatically increase their maize and sorghum yields </li>
        <br></br>
        <li> <strong> 1984 </strong> - becomes a distinguished professor at Texas A&M University
          <br></br>
          <li> <strong> 2005 </strong> - states "we will have to double the world food supply by 2050." Argues that genetically modified crops are the only way we can meet the demand, as we run out of arable land. Says that GM crops are not inherently dangerous
            because "we've been genetically modifying plants and animals for a long time. Long before we called it science, people were selecting the best breeds." </li>
          <br></br>
          <li> <strong> 2009 </strong> - dies at the age of 95. </li>
          <br></br>
          <p> <em> Borlaug's life and achievement are testimony to the far-reaching contribution that one man's towering intellect, persistence and scientific vision can make to human peace and progress."

-- Indian Prime Minister Manmohan Singh </em> </p>
