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.

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.

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.

⚠️ This feature can only be used by logged in users.

  So I think it's worth at least considering building one. 

So let me give you 10 reasons why you might need a website for your business:

  <h2>1. It Impacts Your Credibility </h2>
According to “It takes about 50 milliseconds (that’s 0.05 seconds) for users to form an opinion about your website that determines whether they like your site or not, whether they’ll stay or leave .“
As the old saying goes: “You can only make the first impression once.”

When someone first comes across your business, you want to appear credible.

You want to have an amazing website and social media presence that show the results that you’re delivering and testimonials that you’re getting.

  max-width: 800px;
  margin-left: auto;

quote, blockquote {
  border-top: 2px solid #333;
  border-bottom: 2px solid #333;
  padding: 10px 0;
              $(document).ready(function() {
  // Get all quote elements inside the article
  const articleBody = $('#article');
  const quotes = articleBody.find('quote, blockquote');
  let tweetableUrl = '';
  let clickToTweetBtn = null;
  // Get a url of the current page 
  const currentPageUrl = window.location.href;
  quotes.each(function (index, quote) {
    const q = $(quote);
    // Create a tweetable url
    tweetableUrl = makeTweetableUrl(
      q.text(), currentPageUrl

    // Create a 'click to tweet' button with appropriate attributes
    clickToTweetBtn = $("<a>");
    clickToTweetBtn.text('Click to Tweet');

    clickToTweetBtn.attr('href', tweetableUrl);
    clickToTweetBtn.on('click', onClickToTweet);

    // Add button to every blockquote


function makeTweetableUrl(text, pageUrl) {

  const tweetableText = "" + pageUrl + "&text=" + encodeURIComponent(text);
  return tweetableText;

function onClickToTweet(e) {
    "height=450, width=550, toolbar=0, location=0, menubar=0, directories=0, scrollbars=0"

🕑 One or more of the npm packages you are using needs to be built. You're the first person to ever need it! We're building it right now and your preview will start updating again when it's ready.
