how to change button text color and background color while button is pressed examples

Buttons are an essential part of any user interface design, as they allow users to interact with your app or website. When a user clicks on a button, they might expect the button to change in some way to indicate that it has been pressed. One common way to do this is by changing the button text color and background color.

In this article, we will explore different ways to change a button's text color and background color while it is being pressed, along with some examples.

Method 1: Using CSS pseudo-classes

The simplest way to change the button's text color and background color while it is being pressed is by using CSS pseudo-classes. CSS pseudo-classes are special selectors that allow you to select elements based on their state. Here we will use the :active pseudo-class to select the button when it's pressed.

For example, let's say that we have a button with the following HTML code:

<button class="button">Click me</button>

We can use the following CSS code to change the button's text color and background color when it is pressed:

.button:active {
  color: white;
  background-color: blue;
}

This code selects the .button class when it's in the :active state and changes the color of the text to white and the background color to blue. You can replace the colors with whatever you choose.

Method 2: Using JavaScript

Another way to change the button's text color and background color while it's being pressed is by using JavaScript. JavaScript allows you to add event listeners to elements, which will trigger a function when a certain event occurs. Here, we will use the onclick event to trigger our function.

We can use the following HTML code for our button:

<button class="button" onclick="changeColor()">Click me</button>

We will then add the following JavaScript code to our document:

function changeColor() {
  document.getElementById("button").style.color = "white";
  document.getElementById("button").style.backgroundColor = "blue";
}

This function changes the button's text color and background color when it is clicked. The document.getElementById() method selects the button with the id "button" and applies the specified styles. You can replace the colors with whatever you choose.

Method 3: Using CSS animations

If you want to add some animation to your button, you can use CSS animations to change the button's text color and background color while it's being pressed. CSS animations let you create animations that run smoothly on your website or app without the need for JavaScript.

Here, we will use the following HTML code for our button:

<button class="button">Click me</button>

We can then use the following CSS code to add an animation to our button:

.button {
  color: black;
  background-color: grey;
}

.button:active {
  -webkit-animation: button-press 0.1s ease-out forwards;
  animation: button-press 0.1s ease-out forwards;
}

@-webkit-keyframes button-press {
  0% { transform: scale(1); }
  50% { transform: scale(0.9); }
  100% { transform: scale(1); color: white; background-color: blue; }
}

@keyframes button-press {
  0% { transform: scale(1); }
  50% { transform: scale(0.9); }
  100% { transform: scale(1); color: white; background-color: blue; }
}

This code starts by selecting our button's class (.button) and setting the initial color of the text to black and the background color to grey. When the button is pressed (using the :active pseudo-class), the animation is triggered.

The @-webkit-keyframes and @keyframes rule sets define the animation. The button will scale down to 0.9 times its original size at 50% of the animation and then back to its original size at 100% of the animation. At the same time, the text color will change to white, and the background color will change to blue.

Conclusion

In conclusion, we have looked at several ways to change a button's text color and background color while it's being pressed. You can use CSS pseudo-classes, JavaScript, or CSS animations to achieve this effect. Depending on your needs, you can choose the method that works best for you.

Remember to keep your UI design consistent and user-friendly by following standard conventions. Experiment with different colors and styles, but always ensure that your buttons remain clear and easy to use for your users.

CSS pseudo-classes provide a practical solution to change the color of a button's text and background when it's being pressed or interacts with other states like hovering or focusing. Besides the :active pseudo-class, which selects the button and changes its color while it is being clicked, the :hoverpseudo-class can also change the color when the user hovers over the button. The :focus pseudo-class can change the button color when the user tab or interacts with it through the keyboard.

For example, consider a button with a class .btn-1.

.btn-1 {
  background-color: #2ecc71;
  color: #fff;
}

.btn-1:hover {
  background-color: #27ae60;
}

.btn-1:focus {
  background-color: #27ae60;
}

When the button .btn-1 is hovered, its background color changes to a less-saturated color. If a user uses the keyboard, tabs, or clicks on the button, it changes its background color too.

Event handlers with JavaScript can be used for more complex interactions, or to perform other functions like submitting forms or reloading sections on a page. The onclick event is only one example of many that can be used to change the color of a button's background and text. Other events include ondblclick, onmousedown, onmouseover, and onmouseout.

<button id="myButton" onclick="changeStyles()">Click Me</button>
function changeStyles() {
  var button = document.getElementById("myButton");
  button.style.backgroundColor = "red";
  button.style.color = "white";
}

The changeStyles() function selects the button with the id="myButton" and changes its background color to red and text color to white.

CSS animations allow developers to change the color of a button's text and background in more complex, nuanced ways that can add dynamism and interest to a webpage. Animations can be triggered when a user clicks, hovers over, or interacts with an element.

@keyframes animate-bg-color {
  from {
    background-color: yellow;
  }
  to {
    background-color: blue;
  }
}

button {
  animation-duration: 3s;
  animation-name: animate-bg-color;
  border: none;
  color: #fff;
  font-size: 16px;
  padding: 10px 20px;
}

In the example above, the @keyframes directive sets the animation's movement between the from background color of yellow to the to background color of blue. The animation is applied to the button element with animation-name set to animate-bg-color. The animation animation-duration is set to 3 seconds. When the user clicks on the button, the animation is triggered.

Animations can be more complex, integrating further animation properties to achieve many possible effects.

Overall, changing the color of a button's text and background can create powerful and subtle user experiences that enhance the functionality and aesthetic of a user interface. Experiment with CSS, JavaScript, and animations to find the best technique for your specific use case.

A1. CSS pseudo-classes are selectors that allow developers to select elements based on their state or behavior, such as when the element is being clicked or hovered over.

Q2. What is the onclick event in JavaScript?
A2. The onclick event is a JavaScript event handler that is triggered when an element, in this case, a button, is clicked. It allows developers to execute a function or change the behavior of the element when clicked.

Q3. What are some of the other events that can be used to change the color of a button's text and background?
A3. Some other events that can be used to change the color of a button's text and background include onhover, onfocus, ondblclick, and onmousedown.

Q4. How can you use animations to change the color of a button's text and background when it's pressed?
A4. Animations can be used to change a button's background color and text color when it's pressed by using keyframe animations and animation properties such as animation-duration and animation-name.

Q5. Why is it important to keep your UI design consistent and user-friendly when changing the color of a button's text and background?
A5. Consistency and user-friendliness in UI design ensure that users have a seamless and intuitive experience and can quickly and easily learn how to use and interact with the interface.
