Create a Pagination using HTML, CSS, and JavaScript
Published: 2023-06-19 05:32:05

When we surf any download site or a site from which we can download movies, music, pictures, etc, or let's just consider an example of Google in which at the bottom there are some numbers in ascending order. That number basically indicates the number of pages found in a result for which the user is looking and that section is called **[Pagination](https://www.codewithrandom.com/2023/03/11/pagination-using-html-css-javascript/)**.

So Hey coders Welcome back to Codewithrandom. Today we'll create Pagination Using Html, Css, and JavaScript which is situated at the bottom before the footer in that site which has vast content. I hope you have got an idea for the project.

## HTML Code for Pagination
```
<div id="pagination"></div>
```
In this HTML Code on the name of the structure, we have just used the div tag and given id so that we can call it later. Let's style the Pagination Project using CSS3.

## CSS Code for Pagination
```
html {
    height: 100%;
    width: 100%;
    background-color: #D7D7D7;
    background-image: -webkit-radial-gradient(contain, #F2F2F2, #D1D1D1);
    background-image:    -moz-radial-gradient(contain, #F2F2F2, #D1D1D1);
    background-image:     -ms-radial-gradient(contain, #F2F2F2, #D1D1D1);
    background-image:      -o-radial-gradient(contain, #F2F2F2, #D1D1D1);
    background-image:         radial-gradient(contain, #F2F2F2, #D1D1D1);
}
body {
    margin: 0;
    height: 100%;
    width: 100%;
    text-align: center;
    font-family: Arial, sans-serif;
    background-image:url(image download link in codepen preview below);
}
body:before {
    content: '';
    display: inline-block;
    width: 0; height: 100%;
    vertical-align: middle;
}

#pagination {
    display: inline-block;
    vertical-align: middle;
    border-radius: 4px;
    padding: 1px 2px 4px 2px;
    border-top: 1px solid #AEAEAE;
    border-bottom: 1px solid #FFFFFF;
    background-color: #DADADA;
    background-image: -webkit-linear-gradient(top, #DBDBDB, #E2E2E2);
    background-image:    -moz-linear-gradient(top, #DBDBDB, #E2E2E2);
    background-image:     -ms-linear-gradient(top, #DBDBDB, #E2E2E2);
    background-image:      -o-linear-gradient(top, #DBDBDB, #E2E2E2);
    background-image:         linear-gradient(top, #DBDBDB, #E2E2E2);
}
#pagination a, #pagination i {
    display: inline-block;
    vertical-align: middle;
    width: 22px;
    color: #7D7D7D;
    text-align: center;
    font-size: 10px;
    padding: 3px 0 2px 0;
    -webkit-user-select:none;
       -moz-user-select:none;
        -ms-user-select:none;
         -o-user-select:none;
            user-select:none;
}

#pagination a {
    margin: 0 2px 0 2px;
    border-radius: 4px;
    border: 1px solid #E3E3E3;
    cursor: pointer;
    box-shadow: inset 0 1px 0 0 #FFF, 0 1px 2px #666;
    text-shadow: 0 1px 1px #FFF;
    background-color: #E6E6E6;
    background-image: -webkit-linear-gradient(top, #F3F3F3, #D7D7D7);
    background-image:    -moz-linear-gradient(top, #F3F3F3, #D7D7D7);
    background-image:     -ms-linear-gradient(top, #F3F3F3, #D7D7D7);
    background-image:      -o-linear-gradient(top, #F3F3F3, #D7D7D7);
    background-image:         linear-gradient(top, #F3F3F3, #D7D7D7);
}
#pagination i {
    margin: 0 3px 0 3px;
}
#pagination a.current {
    border: 1px solid #E9E9E9;
    box-shadow: 0 1px 1px #999;
    background-color: #DFDFDF;
    background-image: -webkit-linear-gradient(top, #D0D0D0, #EBEBEB);
    background-image:    -moz-linear-gradient(top, #D0D0D0, #EBEBEB);
    background-image:     -ms-linear-gradient(top, #D0D0D0, #EBEBEB);
    background-image:      -o-linear-gradient(top, #D0D0D0, #EBEBEB);
    background-image:         linear-gradient(top, #D0D0D0, #EBEBEB);
}
```
In this CSS code we have imported a background image and aligned each and every necessary attributes and elements which are the requirement for building the project and also the image we have imported we have padded it from all the side so that it doesn't get messy and project should be displayed in proper way.

Now to make it responsive let's code the JavaScript part.Using the class selector, we will apply the styling to our pagination container after adding some background colour to the project's body in CSS. In addition, we'll change the padding and margin of our project from the browser's default values to zero using the body selector.

## JavaScript Code for Pagination
```
/* * * * * * * * * * * * * * * * *
 * Pagination
 * javascript page navigation
 * * * * * * * * * * * * * * * * */

var Pagination = {

    code: '',

    // --------------------
    // Utility
    // --------------------

    // converting initialize data
    Extend: function(data) {
        data = data || {};
        Pagination.size = data.size || 300;
        Pagination.page = data.page || 1;
        Pagination.step = data.step || 3;
    },

    // add pages by number (from [s] to [f])
    Add: function(s, f) {
        for (var i = s; i < f; i++) {
            Pagination.code += '<a>' + i + '</a>';
        }
    },

    // add last page with separator
    Last: function() {
        Pagination.code += '<i>...</i><a>' + Pagination.size + '</a>';
    },

    // add first page with separator
    First: function() {
        Pagination.code += '<a>1</a><i>...</i>';
    },



    // --------------------
    // Handlers
    // --------------------

    // change page
    Click: function() {
        Pagination.page = +this.innerHTML;
        Pagination.Start();
    },

    // previous page
    Prev: function() {
        Pagination.page--;
        if (Pagination.page < 1) {
            Pagination.page = 1;
        }
        Pagination.Start();
    },

    // next page
    Next: function() {
        Pagination.page++;
        if (Pagination.page > Pagination.size) {
            Pagination.page = Pagination.size;
        }
        Pagination.Start();
    },



    // --------------------
    // Script
    // --------------------

    // binding pages
    Bind: function() {
        var a = Pagination.e.getElementsByTagName('a');
        for (var i = 0; i < a.length; i++) {
            if (+a[i].innerHTML === Pagination.page) a[i].className = 'current';
            a[i].addEventListener('click', Pagination.Click, false);
        }
    },

    // write pagination
    Finish: function() {
        Pagination.e.innerHTML = Pagination.code;
        Pagination.code = '';
        Pagination.Bind();
    },

    // find pagination type
    Start: function() {
        if (Pagination.size < Pagination.step * 2 + 6) {
            Pagination.Add(1, Pagination.size + 1);
        }
        else if (Pagination.page < Pagination.step * 2 + 1) {
            Pagination.Add(1, Pagination.step * 2 + 4);
            Pagination.Last();
        }
        else if (Pagination.page > Pagination.size - Pagination.step * 2) {
            Pagination.First();
            Pagination.Add(Pagination.size - Pagination.step * 2 - 2, Pagination.size + 1);
        }
        else {
            Pagination.First();
            Pagination.Add(Pagination.page - Pagination.step, Pagination.page + Pagination.step + 1);
            Pagination.Last();
        }
        Pagination.Finish();
    },



    // --------------------
    // Initialization
    // --------------------

    // binding buttons
    Buttons: function(e) {
        var nav = e.getElementsByTagName('a');
        nav[0].addEventListener('click', Pagination.Prev, false);
        nav[1].addEventListener('click', Pagination.Next, false);
    },

    // create skeleton
    Create: function(e) {

        var html = [
            '<a>◄</a>', // previous button
            '<span></span>',  // pagination container
            '<a>►</a>'  // next button
        ];

        e.innerHTML = html.join('');
        Pagination.e = e.getElementsByTagName('span')[0];
        Pagination.Buttons(e);
    },

    // init
    Init: function(e, data) {
        Pagination.Extend(data);
        Pagination.Create(e);
        Pagination.Start();
    }
};



/* * * * * * * * * * * * * * * * *
* Initialization
* * * * * * * * * * * * * * * * */

var init = function() {
    Pagination.Init(document.getElementById('pagination'), {
        size: 30, // pages size
        page: 1,  // selected page
        step: 3   // pages before and after current
    });
};

document.addEventListener('DOMContentLoaded', init, false);
```
With javascript, we'll first create a variable for pagination, then convert the data inside of it. Using functions, we'll then make the function for our javascript and produce a string of numbers for the project. the number will then be displayed inside of our website utilizing the display property.

In this JavaScript we have made it responsive and for that the id which we have defined in the HTML code we have called it and then we have set the size for the pagination and set the size of each page because when you go to next page the size should be same as the previous. Let's see the output.

We have successfully created our **[Pagination](https://www.codewithrandom.com/2023/03/11/pagination-using-html-css-javascript/)** using HTML, CSS, and JavaScript. You can use this project for your personal needs and the respective lines of code are given with the code pen link mentioned above.
