Start by brainstorming ideas for your web page. Think about what kind of content you want to include, how you want it to look, and what kind of interactivity you want to add with JavaScript. Sketch out a rough design on paper.
Once you have an idea of what you want to create, it's time to start coding. Begin by setting up your project in Codepen. Create a new pen and add the basic structure of an HTML document.
<!DOCTYPE html>
<html>
<head>
<title>Your Web Page</title>
</head>
<body>
</body>
</html>
Next, start adding content to your page using HTML. Remember to use a variety of different elements to structure your content, such as headings, paragraphs, lists, images, and links. Consider how you can use forms and input elements to add interactivity.
Once you've added some content, start styling your page with CSS. Try to make your page visually appealing and easy to read. Experiment with different colors, fonts, and layouts. Remember to use CSS selectors effectively to target the elements you want to style.
Finally, add some interactivity to your page with JavaScript. This could be something simple like a form that validates user input, or something more complex like a game or a dynamic data display. Remember to test your JavaScript thoroughly to make sure it works as expected.
