Learn How to Style Round Buttons with CSS


In the ever-evolving world of web development, creating visually appealing and user-friendly interfaces is crucial. One essential aspect of this process is styling buttons, which can significantly impact the overall user experience. Among various button designs, round buttons have gained popularity for their modern and sleek appearance. In this comprehensive guide, we will delve into the art of how to style round buttons with CSS. By the end of this tutorial, you’ll be equipped with the knowledge to create eye-catching round buttons that elevate your website’s aesthetics and improve user interaction.

Understanding HTML and CSS Basics

Before we dive into the world of round buttons, let’s ensure we have a solid foundation in HTML and CSS—the dynamic duo responsible for designing webpages. HTML (HyperText Markup Language) provides the structural elements, while CSS (Cascading Style Sheets) takes care of the presentation, such as colors, fonts, and layout.

To create a button, you’ll need an HTML element like <button> or <a> with the desired text inside, like this:

<button class="round-btn">Click Me</button>

To apply CSS styles to this button, you’ll need to create a separate CSS file and link it to your HTML. Here’s how you do it:

<link rel="stylesheet" href="style.css">

Creating the Round Button

Now that we have the basics covered, let’s embark on our journey to create the perfect round button step-by-step.

Step 1: Applying Basic Styles

To begin, we’ll define some fundamental styles for our button. This includes setting the background color, text color, padding, and other necessary properties. Let’s look at an example CSS code snippet:

.round-btn {
  background-color: #3498db;
  color: #ffffff;
  padding: 12px 24px;
  border: none;
  text-align: center;
  text-decoration: none;
  display: inline-block;
  font-size: 16px;
  border-radius: 50px;

Step 2: Adding Border Radius

The magic behind creating round buttons lies in the border-radius property. This property allows you to round the corners of an element, effectively turning a square or rectangular button into a perfect circle. To achieve a circular shape, you need to set the border-radius value to half of the button’s width or height.

.round-btn {
  border-radius: 50%;

In the example above, the border-radius property is set to 50%, making the button perfectly round. You can adjust this value to create buttons with varying levels of roundness.

Step 3: Styling the Text

The text within the button is just as important as its shape and color. You can apply various CSS properties to style the text inside the button, such as choosing an appropriate font, adjusting the font size, and aligning the text within the button.

.round-btn {
  font-family: "Arial", sans-serif;
  font-size: 16px;
  font-weight: bold;
  text-align: center;
  line-height: 24px;

In the example above, we’ve set the font family to “Arial” or any sans-serif font available on the user’s system. The font size is set to 16px, with a bold weight to make the text stand out. The text-align property is set to center, ensuring that the text is horizontally centered within the button. The line-height property is adjusted to 24px, which helps vertically center the text within the button and adds a bit of breathing space between lines of text.

Step 4: Adding Hover Effects

Hover effects add interactivity to buttons, providing visual feedback to users when they interact with them. When a user hovers over the button, you can change its background and text colors, create animations, or apply other visual changes.

.round-btn:hover {
  background-color: #45aaf2;
  color: #ffffff;

In the example above, we’ve added a hover effect that changes the button’s background color to #45aaf2 (a lighter shade of blue) and the text color to #ffffff (white). This creates a visually appealing highlight effect when users hover over the button.

Customizing Button Colors

Customizing the colors of your round buttons can greatly impact their visual appeal and overall design. There are three primary colors to consider when styling your buttons: the background color, the text color, and the colors for the hover and active states.

Background Color

The background color sets the base color of your button. Choose a color that fits well with your website’s color scheme and branding.

.round-btn {
  background-color: #3498db; /* Blue background color */

In the example above, the background color is set to #3498db, which is a shade of blue. You can experiment with different colors to find the perfect match for your website’s design.

Text Color

The text color should contrast well with the background color to ensure readability. A common approach is to use white text on a dark background or vice versa.

.round-btn {
  color: #ffffff; /* White text color */

In the example above, we’ve set the text color to #ffffff, which is white. This ensures that the text stands out and remains easily readable against the blue background.

Hover and Active States

The hover and active states refer to the visual changes applied to the button when users interact with it. Providing visual feedback during these interactions can improve the user experience.

.round-btn:hover {
  background-color: #45aaf2; /* Lighter blue on hover */

.round-btn:active {
  background-color: #1f65a3; /* Darker blue on click */

In the example above, when a user hovers over the button, the background color changes to #45aaf2, a lighter shade of blue. Similarly, when the user clicks on the button, the background color changes to #1f65a3, a darker shade of blue. These changes create a sense of interactivity and engagement for the user.

Adjusting Button Size and Position

The size and position of your buttons can significantly impact their visibility and overall layout on the page. Proper sizing and positioning can help create a harmonious design.

Adjusting Width and Height

You can customize the width and height of the round button to fit your design requirements. Ensure that the button is large enough to be easily clickable but not too big to overpower other elements on the page.

.round-btn {
  width: 150px;
  height: 50px;

In the example above, the width of the button is set to 150px, and the height is set to 50px. You can adjust these values according to your design needs.

Centering the Button

Centering buttons within their containers can create a balanced and visually pleasing layout. CSS provides several methods for centering elements horizontally and vertically.

.container {
  display: flex;
  justify-content: center;
  align-items: center;

In the example above, the button is placed inside a container with the class name container. The display: flex property is used to create a flex container, and justify-content: center and align-items: center are used to center the button both horizontally and vertically within the container. This ensures that the button remains centered even if the container’s size changes.

Advanced Styling Techniques

Now that you have mastered the basics, let’s explore some advanced styling techniques to elevate your round buttons even further.

Adding Box Shadow

Box shadow is a popular CSS property that adds a subtle sense of depth and dimension to elements, giving them a slightly raised appearance. This technique can be applied to round buttons to make them stand out from the page.

.round-btn {
  box-shadow: 0px 2px 4px rgba(0, 0, 0, 0.2);

In the example above, we’ve added a box shadow to the button with the values 0px 2px 4px rgba(0, 0, 0, 0.2). The first two values represent the horizontal and vertical offset of the shadow, while the third value represents the blur radius, creating a softer shadow effect. The last value is the color of the shadow, specified as an RGBA value (rgba(0, 0, 0, 0.2)), which is a semi-transparent black color.

Using Transitions for Smooth Effects

CSS transitions allow you to add animation and smoothness to button interactions. Transitions are applied to CSS properties, and when those properties change, the transition effect is triggered.

.round-btn {
  transition: background-color 0.2s ease-in-out;

In the example above, we’ve added a transition effect to the background-color property of the button. When the background color changes (e.g., on hover), the transition effect will take place over a duration of 0.2s (200 milliseconds), using the ease-in-out timing function, which creates a smooth and gradual change in the background color.

Incorporating Icon Fonts

Icons can make your round buttons more expressive and informative.

Instead of using image icons, which can increase page load time, you can use icon fonts to add icons to your buttons. Icon fonts are fonts that contain icons as characters, allowing you to easily include them in your HTML.

<button class="round-btn">
  <i class="material-icons">favorite</i> Like

In the example above, we’ve added an icon to the button using the <i> element with the class name material-icons. The text “favorite” represents the icon we want to display. Icon fonts, such as Google’s Material Icons or Font Awesome, provide a wide variety of icons that you can use in your buttons and other elements.

Responsive Round Buttons

In today’s mobile-driven world, responsive design is essential for providing an optimal user experience across various devices, from large desktop screens to small smartphones.

Media Queries

Media queries allow you to apply different styles based on the user’s device screen size or other device-specific properties. By using media queries, you can make your round buttons adapt to different screen sizes and orientations.

@media screen and (max-width: 768px) {
  .round-btn {
    font-size: 14px;
    width: 120px;
    height: 40px;

In the example above, we’ve used a media query to target screens with a maximum width of 768px, which typically represents smaller devices such as tablets or smartphones. Inside the media query, we’ve adjusted the font size, width, and height of the button to make it more suitable for smaller screens. This ensures that your round buttons remain readable and accessible on various devices.

Scaling with Flexbox

Flexbox is a powerful layout model in CSS that simplifies the process of creating responsive and flexible designs. By using flexbox, you can create dynamic button layouts that adjust automatically based on the available space.

.container {
  display: flex;
  flex-wrap: wrap;
  justify-content: center;

In the example above, the buttons are placed inside a container with the class name container. The display: flex property turns the container into a flex container, and flex-wrap: wrap allows the buttons to wrap to the next line if they don’t fit in a single row. The justify-content: center property centers the buttons horizontally within the container. With flexbox, your buttons will adapt to different screen sizes and layouts, providing a smooth and seamless user experience.

Testing and Browser Compatibility

Before deploying your round buttons to a live website, it’s essential to test them thoroughly to ensure they function as expected and appear correctly in different browsers.

Tools for Testing Button Styles

Several online tools and browser extensions can help you preview and fine-tune your button styles before implementing them on your website. Some popular tools include:

  • CodePen: CodePen is an online code editor that allows you to write and preview HTML, CSS, and JavaScript code in real-time. You can create a new pen and test your button styles within the editor.
  • Browser Developer Tools: All modern browsers come with built-in developer tools that allow you to inspect and modify the CSS of a webpage. You can use these tools to test your round buttons and make adjustments as needed.

Checking Compatibility Across Browsers

While CSS is widely supported across modern browsers, some older versions or less common browsers may display your round buttons differently. It’s essential to test your buttons in various browsers to ensure a consistent experience for all users.

.round-btn {
  /* Styles for all modern browsers */

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
  .round-btn {
    /* Styles specific to Internet Explorer */

In the example above, we’ve used a media query to target Internet Explorer (IE), which may have different rendering behaviors. By applying specific styles for IE, you can ensure that your round buttons appear correctly in this browser as well.

Best Practices for Button Design

Now that you have the skills to create stunning round buttons let’s explore some best practices to optimize their design.

Simplicity and Clarity

Keep your button design simple and avoid unnecessary clutter. Users should quickly understand the purpose of the button. Avoid using too many colors or distracting elements that might confuse users.

Consistency with Branding

Ensure that your button design aligns with your website’s overall branding and design language. Consistency in design helps users recognize and trust your brand.

Mobile-Friendly Design

Optimize your round buttons for mobile devices to cater to users on the go. Ensure that buttons are large enough to be easily tapped with a finger and that the text remains readable on smaller screens.
