How to use CSS3 to create beautiful and interactive buttons

In modern web design, buttons have always been one of the indispensable elements. Whether in form input, navigation menus, or page interactions, buttons are the key to user action. In order to improve the user experience, we need to pay attention to the beauty and interactivity of buttons in design. CSS3 technology provides many native button styles and properties. This article will introduce how to use CSS3 to implement beautiful and highly interactive buttons.

1. Basic CSS styles

First, let’s define some basic CSS styles. In HTML, we often use the "" tag to create buttons. The following is some basic CSS code to change the style of the button to be more readable and beautiful.

button {
  display: inline-block;
  border: none;
  border-radius: 4px;
  padding: 10px 20px;
  font-size: 16px;
  font-weight: bold;
  text-align: center;
  color: #fff;
  background-color: #007aff;
  cursor: pointer;
  transition: background-color 0.2s ease;
}

In this code, the "display: inline-block" and "border: none" attributes set the button to an inline block element without a border. The "border-radius" property sets the corners to arcs, flattening the appearance of the entire button. The "padding" property adjusts the button padding size to 10 pixels for the top and bottom sides, and 20 pixels for the left and right sides, making it more spacious and clickable. The "font-size" and "font-weight" properties make text easier to read and separate. The "text-align: center" attribute centers the text in the label horizontally, which is important because buttons often contain multiple lines of text. The "color" and "background-color" properties control the color of text and background. Finally, the "cursor: pointer" will control the cursor type when the mouse is hovering over the button, and the "transition" property will control the gradient transition effect of the background color.

2. Hover Effect

Through CSS3, we can apply special effects when the mouse hovers over the button. The following is some CSS hover effect code that makes the button more vivid:

button:hover {
  background-color: #4ea4f4;
}

In this code, based on the "button" style code, we add a ":hover" pseudo-class selector, which Will change the button's background color. Using the ":hover" selector, we can change the background color of the button from a regular color to a more saturated blue when the user hovers over it.

3. The activity state of the button

After the user clicks the button and re-enables its function, you can see the activity state of the button. In order to achieve this effect, we can use the ":active" pseudo-class selector, which can change the appearance of the button when the button is pressed, for example, the button appearance changes from light to dark.

button:active {
  background-color: #005cb9;
  box-shadow: 0 4px 8px rgba(0,0,0,0.15);
  transform: translateY(1px);
}

This code also implements the ":active" selector on the "button" basic style. It will change the appearance of the button by changing the background color, adding a box shadow and a slight displacement of the button. Therefore, these subtle changes make the button more active and spiritual compared to the usual button.

4. Add Icons to Buttons

Obviously, modern web design doesn’t just stop at fonts and block elements. We usually use icons in user interfaces. Therefore, adding icons to buttons is one of the important means to make them more attractive and easily identifiable. Scalable vector graphics can be implemented quickly using font icons or SVG icons, and they are also very friendly to the performance and SEO of your website. Here is the CSS code for a button with a "Search" icon added:

button[data-icon]:before {
  font-family: 'FontAwesome';
  content: attr(data-icon);
  padding-right: 5px;
}

This code sets the "data-icon" attribute, which is attached as a custom attribute of the button onto the button and after that can be used in CSS. The "font-family" property is set to the FontAwesome font, which is the most widely used icon font. We need to first introduce the FontAwesome CSS file in the head of the HTML file. Finally, the ":before" pseudo-class selector is used to add a pseudo-class element with an icon generated based on the "data-icon" attribute before the button.

5. Round button

CSS also allows us to change the button to a round shape. This is a sample code to implement a round button:

button.round {
  border-radius: 50%;
  width: 50px;
  height: 50px;
  padding: 0;
  text-indent: -999999px;
  border: none;
  background: #007aff url('/path/to/image') no-repeat center center / contain;
}

This CSS code creates a "round" class style. In the above code, we set the button's "border-radius" property to 50%, turning the button into a circle. Setting the "height" and "width" properties to 50px will resize the button's height and width to the same size. At this time, "text-indent: -999999px;" is used in the text, which makes the text extend beyond the left side of the text block and hides it off the screen. This way, the rounded shape is preserved and the text content is prevented from interfering with the button. Finally, the "background" property is used to set the background of the circular button, including color, image path, and position.
