In this article you'll see how to style a button using CSS.
My goal here is mostly to showcase how different CSS rules and styles are applied and used. We won't see much design inspiration nor will we discuss ideas for styling.
Instead, this will be more of an overview of how the styles themselves work, what properties are commonly used, and how they can be combined.
You'll first see how to create a button in HTML. Then you'll learn how to override the default styles of buttons. Lastly, you'll get a glimpse of how to style buttons for their three different states.

Let's get started!
How to Create a Button in HTML
To create a button, use the <button>
element.
This is a more accessible and semantic option compared to using a generic container which is created with the <div>
element.
In the index.html
file below, I've created the basic structure for a webpage and added a single button:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <link rel="stylesheet" href="style.css"> <title>CSS Button Style</title> </head> <body> <button type="button" class="button">Click me!</button> </body> </html>
Let's break down the line <button type="button" class="button">Click me!</button>
:
- You first add the button element, which consists of an opening
<button>
and closing</button>
tag. - The
type="button"
attribute in the opening<button>
tag explicitly creates a clickable button. Since this particular button is not used for submitting a form, it is useful for semantic reasons to add it in order to make the code clearer and not trigger any unwanted actions. - The
class="button"
attribute will be used to style the button in a separate CSS file. The valuebutton
could be any other name you choose. For example you could have usedclass="btn"
. - The text
Click me!
is the visible text inside the button.
Any styles that will be applied to the button will go inside a spearate style.css
file.
You can apply the styles to the HTML content by linking the two files together. You do this with the <link rel="stylesheet" href="style.css">
tag which was used in index.html
.
In the style.css
file, I've added some styling which only centers the button in the middle of the browser window.
Notice that the class="button"
is used with the .button
selector. This is a way to apply styles directly to the button.
* { box-sizing: border-box; } body { display:flex; justify-content: center; align-items: center; margin:50px auto; } .button { position: absolute; top:50% }
The code from above will result in the following:
The default styling of buttons will vary depending on the browser you're using.
This is an example of how the native styles for buttons look on the Google Chrome browser.
How to Change the Default Styling of Buttons
How to Change the Background Color of Buttons
To change the background color of the button, use the CSS background-color
property and give it a value of a color of your taste.
In the .button
selector, you use background-color:#0a0a23;
to change the background color of the button.
.button { position: absolute; top:50%; background-color:#0a0a23; }
How to Change the Text Color of Buttons
The default color of text is black, so when you add a dark background color you will notice that the text has disappeared.
Another thing to make sure of is that there is enough contrast between the button's background color and text color. This helps make the text more readable and easy on the eyes.
Next, use the color
property to change the color of text:
.button { position: absolute; top:50%; background-color:#0a0a23; color: #fff; }
How to Change the Border Style of Buttons
Notice the grey around the edges of the button? That is the default color of the button's borders.
One way to fix this is to use the border-color
property. You set the value to be the same as the value of background-color
. This makes sure the borders have the same color as the background of the button.
Another way would be to remove the border around the button entirely by using border:none;
.
.button { position: absolute; top:50%; background-color:#0a0a23; color: #fff; border:none; }
Next, you can also round-up the edges of the button by using the border-radius
property, like so:
.button { position: absolute; top:50%; background-color:#0a0a23; color: #fff; border:none; border-radius:10px; }
You could also add a slight dark shadow effect around the button by using the box-shadow
property:
position: absolute; top:50%; background-color:#0a0a23; color: #fff; border:none; border-radius:10px; box-shadow: 0px 0px 2px 2px rgb(0,0,0);
How to Change the Size of Buttons
The way to create more space inside the button's borders is to increase the padding
of the button.
Below I added a value of 15px for the top, bottom, right, and left padding of the button.
I also set a minimum height and width, with the min-height
and min-width
properties respectively. Buttons need to be large enough for all different kind of devices.
.button { position: absolute; top:50%; background-color:#0a0a23; color: #fff; border:none; border-radius:10px; padding:15px; min-height:30px; min-width: 120px; }
How to Style Button States
Buttons have three different states:
-
:hover
-
:focus
-
:active
It's best that the three states are styled differently and don't share the same styles.
In the following sections I'll give a brief explanation on what each one of the states mean and what triggers them. You'll also see some ways you can style the button for each separate state.
How to Style :hover
States
The :hover
state becomes present when a user hovers over a button, by bringing their mouse or trackpad over it, without selecting it or clicking on it.
To change the button's styles when you hover over it, use the :hover
CSS
pseudoclass selector.
A common change to make with :hover
is switching the background-color of the button.
To make the change less sudden, pair :hover
with the transition
property.
The transition
property will help make the transition from no state to a :hover
state much smoother.
The change of background color will happen a bit slower than it would without the transition
property. This will also help make the end result less jarring for the user.
.button:hover { background-color:#002ead; transition: 0.7s; }
In the example above, I used a Hex color code value to make the background color a lighter shade for when I hover over the button.
With the help of the transition
property I also caused a delay of 0.7s
when the transition from no state to a :hover
state happens. This caused a slower transition from the original #0a0a23
background color to the #002ead
background color.
Keep in mind that the :hover
pseudoclass does not work for mobile device screens and mobile apps. Choose to use hover effects only for desktop web applications and not touch screens.
How to Style :focus
States
The :focus
state takes effect for keyboard users - specifically it will activate when you focus on a button by hitting the Tab
key (⇥
).
If you're following along, when you focus on the button after pressing the Tab
key, you'll see the following:
Notice the slight light blue outline around the button when it's gained focus?
Browsers have default styling for the :focus
pseudoclass, for accessibility keyboard navigation purposes. It's not a good idea to remove that outline
altogether.
You can however create custom styles for it and make it easily detectable.
A way to do so is by setting the outline color to first be transparent
.
Following that, you can maintain the outline-style
to solid
. Lastly, using the box-shadow
property, you can add a color of your liking for when the element is focused on:
.button:focus { outline-color: transparent; outline-style:solid; box-shadow: 0 0 0 4px #5a01a7; }
You can also again pair these styles with the transition
property, depending on the effect you want to achieve:
.button:focus { outline-color: transparent; outline-style:solid; box-shadow: 0 0 0 4px #5a01a7; transition: 0.7s; }
How to Style for the :active
State
The :active
state gets activated when you click on the button by either clicking the computer's mouse or pressing down on the laptop's trackpad.
That being said, look at what happens when I click the button after I've applied and kept the styles for the :hover
and :focus
states:
The :hover
state styles are applied before clicking when I hover over the button.
The :focus
state styles are applied also, because when a button is clicked it also gains a :focus
state alongside an :active
one.
However, keep in mind that they are not the same thing.
:focus
state is when an element is being focused on and :active
is when a user clicks
on an element by holding and pressing down on it.
To change the style for when a user clicks a button, apply styles to the :active
CSS pseudoselector.
In this case, I've changed the background color of the button when a user clicks on it
.button:active { background-color: #ffbf00; }
