Medium and Big enterprise-level websites all require a search functionality in their website so that users can search for something particular across their website.

This search functionality provides a pleasant user experience and users land straight to the resource they are looking for.

In this blog post, we will create an animated full-page search bar for our website using HTML, CSS, and Javascript.

First, we will start by creating the HTML and CSS for the header which has the search button in the header.

The HTML for the header with the search button will look like this:

The CSS code for this header looks like this:

Now, we will create a full-page overlay screen that will have the search input textbox.

The HTML for this full-page search box looks like this:

The CSS for the full page animated search looks like this:

And the result of the above HTML and CSS produces a result like this:

Now that we have the structure ready, we will use Javascript to show this search page only when the user clicks on the search button.

We will first create a "hidden" CSS class which will change the visibility of the element to hidden.

Now, it's time to add the Javascript file to the HTML file.

We basically toggle the hidden class in the full page search container.

The final result looks like this:
