How do I create a CSS-only responsive calendar layout?

Creating a CSS-Only Responsive Calendar Layout

Creating a responsive calendar layout using only CSS can be a simple yet effective way to display dates on your website. With the power of Flexbox and Grid layout systems, we can easily achieve this without the need for any JavaScript. In this blog post, we will learn how to create a CSS-only responsive calendar layout step by step, with code examples and comments.

Step 1: Set up the HTML structure

First, let’s create the basic HTML structure for our calendar layout. We will create a table with rows and cells to represent the days of the week and dates in a month.

<!-- HTML -->
<!DOCTYPE html>
<html lang="en">
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>CSS-Only Responsive Calendar Layout</title>
  <link rel="stylesheet" href="styles.css">
  <div class="calendar">
    <div class="calendar-header">
    <div class="calendar-body">
      <!-- Add 42 cells for dates here -->

Step 2: Basic CSS Styling

Now, let’s add some basic CSS styling for the calendar layout.

/* CSS */
body {
font-family: Arial, sans-serif;
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
margin: 0;

.calendar {
border: 1px solid #ccc;

.calendar-header, .calendar-body {
display: flex;
flex-wrap: wrap;

.calendar-header span, .calendar-body div {
flex-basis: calc(100% / 7);
display: flex;
justify-content: center;
align-items: center;
height: 40px;
box-sizing: border-box;

.calendar-header span {
font-weight: bold;
background-color: #f5f5f5;
border-bottom: 1px solid #ccc;

.calendar-body div {
border: 1px solid #ccc;

Step 3: Responsive Styling

To make the calendar layout responsive, we will add media queries and adjust the font-size and cell height accordingly.

/* CSS */
@media (max-width: 767px) {
.calendar-header span, .calendar-body div {
font-size: 12px;
height: 30px;

@media (min-width: 768px) and (max-width: 1023px) {
.calendar-header span, .calendar-body div {
font-size: 14px;
height: 35px;

Step 4: Populate the calendar with dates

Finally, let’s populate the calendar body with 42 cells (6 rows x 7 columns) to represent the maximum number of dates that can be displayed in a month.

<!-- HTML -->
<!-- Add this inside the .calendar-body div in your HTML file -->
<!-- Add more cells up to 42 -->


In this blog post, we learned. Lastly, we populated the calendar with dates. This CSS-only responsive calendar layout can be easily customized and extended to fit your project requirements. You may also consider adding more interactivity and accessibility features using JavaScript or other web development techniques.

Possible enhancements:

  1. Highlighting the current date: You can add a class to the current date cell and style it differently using CSS.
  2. Adding navigation buttons: You can add next and previous buttons to navigate between months, and implement the functionality using JavaScript.
  3. Customizing the appearance: You can easily customize the calendar’s appearance by changing the colors, fonts, and other design elements in the CSS.
  4. Displaying events: If you need to display events on specific dates, you can add an additional data attribute to the cells and use JavaScript to fetch and display the relevant information.

We hope this guide helps you create your own CSS-only responsive calendar layout for your projects. Happy coding!
