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.

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.

  <h1>CSS Linear Gradients</h1>
  <p class="intro">CSS <code>linear-gradient()</code> and <code>repeating-linear-gradient()</code> functions allow to compute amazing gradients without need to use external graphics software. Get more details <a href="https://ideaspot.tv/css-linear-gradient-gradient-background-css/" target="_blank">here</a>.</p>

  <section class="history">
    <!--
            To create a basic gradient, simply use linear-gradient function and provide
            two colors. Here I am using the color names, but you can use everything
            that is available for colors, so you can use hexadecimal values
            or RGB etc.
        -->
    <div style="background: linear-gradient(black, darkcyan)"><span>default</span></div>

    <!--
            By default the gradient goes top to bottom. You can change it by setting
            the quantity of turns. 0.25turn, 0.50turn etc.
        -->
    <div style="background: linear-gradient(0.25turn, black, darkcyan)"><span>0.25turn</span></div>
    <div style="background: linear-gradient(0.50turn, black, darkcyan)"><span>0.50turn</span></div>
    <div style="background: linear-gradient(0.75turn, black, darkcyan)"><span>0.75turn</span></div>
    <div style="background: linear-gradient(1turn, black, darkcyan)"><span>1turn</span></div>

    <!--
            You can also specify the element sides and corners.
        -->
    <div style="background: linear-gradient(to left, black, darkcyan)"><span>to left</span></div>
    <div style="background: linear-gradient(to right, black, darkcyan)"><span>to right</span></div>
    <div style="background: linear-gradient(to bottom, black, darkcyan)"><span>to bottom</span></div><!--default-->
    <div style="background: linear-gradient(to top, black, darkcyan)"><span>to top</span></div>
    <div style="background: linear-gradient(to bottom right, black, darkcyan)"><span>to bottom right</span></div>

    <!--
            Alternatively, for more control, you can use degrees. 0 degrees is to top
            and then as you increase it goes clockwise.
        -->
    <div style="background: linear-gradient(0deg, black, darkcyan)"><span>0deg</span></div><!-- to top; clockwise rotation -->
    <div style="background: linear-gradient(45deg, black, darkcyan)"><span>45deg</span></div>
    <div style="background: linear-gradient(-45deg, black, darkcyan)"><span>-45deg</span></div>

    <!--
            If we specify the gradient direction from left to right, then the first color
            is set to be at the very left, and the second color at the very end.
            And all between is a mix between those two colors. The mix goes proportionally
            to distance between two colors, so in the middle, at 50% we have equal mix
            between the left and right color.
        -->
    <div style="background: linear-gradient(to right, darkcyan, brown)"><span>default positioning</span></div>

    <!--
            We can provide the percentage value explicitly.
        -->
    <div style="background: linear-gradient(to right, darkcyan, 50%, brown)"><span>positioning 50%</span></div>

    <!--
            Or we can adjust. 25% would shift the mixing to the left, and 75% to the right.
        -->
    <div style="background: linear-gradient(to right, darkcyan, 25%, brown)"><span>positioning 25%</span></div>
    <div style="background: linear-gradient(to right, darkcyan, 75%, brown)"><span>positioning 75%</span></div>

    <!--
            We can create a gradient between more than two colors.
            Let's add cyan in between the two existing ones.
        -->
    <div style="background: linear-gradient(to right, black, cyan, darkcyan)"><span>more colors</span></div>

    <!--
            By default the middle color is put right in the middle, at 50%.
            But we can adjust, so here it is at 25%. Or 75%.
        -->
    <div style="background: linear-gradient(to right, black, cyan 25%, darkcyan)"><span>positioning middle color (25%)</span></div>
    <div style="background: linear-gradient(to right, black, cyan 75%, darkcyan)"><span>positioning middle color (75%)</span></div>

    <!--
            We can use this feature to control how wide each stripe is, and how
            soft or sharp is the transition from one color to another.
        -->
    <div style="background: linear-gradient(to right, black 33%, black 33%, cyan 33%, cyan 67%, darkcyan 67%, darkcyan 100%)"><span>positioning each color</span></div>

    <!--
            For the last basic example, let's go max with the number of colors
            and let's create a rainbow: red, orange, yellow, green, blue, indigo and violet.
        -->
    <div style="background: linear-gradient(to right, red, orange, yellow, green, blue, indigo, violet)"><span>rainbow</span></div>

    <!--
            Finally, to make the stripes sharp, we will divide the 100% eqaully,
            that is around 14% for each.
        -->
    <div style="background: linear-gradient(to right, red 14%, orange 14%, orange 28%, yellow 28%, yellow 42%, green 42%, green 58%, blue 58%, blue 72%, indigo 72%, indigo 86%, violet 86%)"><span>sharp stripes</span></div>


    <!--
            We can also create a gradient from a color to a transparency.
        -->
    <div style="background: linear-gradient(0deg, red, transparent);"><span>transparency</span></div>

    <!--
            Or we can use hexadecimal values for even more ALPHA channel control.
        -->
    <div style="background: linear-gradient(0deg, #FF0000AA, #FF000000);"><span>transparency</span></div>

    <!--
            Finally, we can use the CSS3 background layers feature to overlay
            one gradient over the other. Here I will set three gradients - red, green and blue.
            The red will start at 0degrees, the green at 120 degrees and blue at 240 degrees.
        -->
    <div style="background:
                linear-gradient(0deg, #FF0000AA, #FF000000),
                linear-gradient(120deg, #00FF00AA, #00FF0000),
                linear-gradient(240deg, #0000FFAA, #0000FF00)
                "><span>layers (deg)</span></div>

    <!--
            With these particular degree values, we can achieve similar effect by using
            sides and corners instead of numbers.
        -->
    <div style="background:
                linear-gradient(to top, #FF0000AA, #FF000000),
                linear-gradient(to top right, #00FF00AA, #00FF0000),
                linear-gradient(to top left, #0000FFAA, #00FF0000)
                "><span>layers (sides)</span></div>

    <!--
            And finally something really amazing. We can use put a gradient layer
            on top of an existing image background. Here let's add a mist over this
            mountainy photoshoot.
        -->
    <div style="background:
                linear-gradient(to bottom, mistyrose, transparent),
                url('https://images.pexels.com/photos/2416864/pexels-photo-2416864.jpeg?auto=compress&cs=tinysrgb&w=600');
                background-size: cover;
                "><span>mist effect</span></div>

    <!--
            Let's use the gradient to create a single 2-color stripe at the left of our div.
        -->
    <div style="background: linear-gradient(to right, black, darkcyan 10px, black 20px)"><span>single stripe</span></div>

    <!--
            That created a single stripe. If we now wanted this stripe to be repeated,
            to create a kind of a texture, we can use the repeating-linear-gradient function.
        -->
    <div style="background: repeating-linear-gradient(to right, black, darkcyan 10px, black 20px)"><span>repeated (px)</span></div>

    <!--
            Instead of pixels we can use percents.
        -->
    <div style="background: repeating-linear-gradient(to right, black, darkcyan 10%, black 20%)"><span>repeated (%)</span></div>

    <!--
            And finally, we can provide the exact values of color stops, in order to
            make the strips sharp.
        -->
    <div style="background: repeating-linear-gradient(to right, black, black 10%, darkcyan 10%, darkcyan 20%)"><span>repeated (sharp)</span></div>
