Horizontal Timeline Using Html Css Javascript Source Code
We create a horizontal timeline in this article, and we share complete code. We create this horizontal timeline using html, css, and javascript. This is not a simple timeline this is e animation horizontal timeline, so let’s create it.
Write Html Code first!

</html>This is our whole Html code for this horizontal timeline. In another project, Html code is very basic. But in this timeline, there are lots of important Html tags like Data-date, and aria-hidden so carefully read the Html code and see what tags work. You can comment us that tag to see what happens in the project🥶.
This is our output with only Html code. Then we write Css and javascript for the horizontal timeline.

This is almost 500 lines of code css. We write mobile-friendly also so when users see this horizontal timeline on mobile it is responsive. We use all browsers like firefox Moz, opera, safari, and chrome. We use before after for moving our horizontal timeline.
We use a lot of new properties in css, most of the new css tags. In the last codes of the line for mobile-friendly design. Then we use the keyframe for creating animation in the timeline.
So that’s it for css code you can see the output below with only html css, then we write javascript (jquery) to complete our timeline project🔥.
Css Updated Output
This is a blank photo of css update output, many people think that is what happens so now when we add javascript(jquery) code to our timeline it’s visible.
50+ Frontend Project With Code
So write javascript code for our final output.

});This is our final code of javascript (jquery). This code is very lengthy we write code for functionality like we write code using css then we write javascript so it has interactive, hope you understand😉 jquery code.
Let’s see our horizontal timeline output.
Final Output
This is a screenshot of our horizontal timeline project, and we share this video output so you can see an exact preview of the timeline. We use html, css, and javascript (jquery) code for this awesome👏 project.
Hope you like this project, we create your own and use this project in any project as a part project like the reviews section, and contact form. If you need any more project-related frontend. Visit our homepage and you get 100+ projects💝.
