close button html

The close button in HTML is used to close a window or pop-up box in a web page or application. The close button is generally an icon or text, and the user can close the current window or pop-up box by clicking the button. This article will introduce the close button in HTML and how to implement different types of close buttons.

1. Basic usage of the close button

In HTML, the most basic close button is a button element. The specific implementation is as follows:

关闭

Implementation of this close button The method is very simple. When the user clicks the button, the window.close() function of JavaScript will be called to close the current window.

2. Icon style of close button

In addition to text buttons, we can also use pictures or icons to implement close buttons to add visual effects. Commonly used closing icons include X, ×, etc., which can be implemented using font icons or custom pictures. The following are two implementation methods:

1. Use font icons

Font icons can specify colors, sizes and other styles through CSS, which is more flexible and convenient. Moreover, the font icons can be adapted to screens with different resolutions, making them clearer and smoother. The following is an example of a close button using the Font Awesome font icon:

Here we use the link element to import the Font Awesome CSS file, and then nest an i## in the button # element, set its class attribute to fas fa-times, which means using the times icon. When the user clicks the close button, JavaScript's window.close() is executed.

img element in the button and use the src attribute to specify the URL of the image, ## The #alt attribute is the description of the image. When the user clicks the button, JavaScript's window.close() is executed. 3. Style design of the close button

Good-looking buttons can often improve user experience. Now let’s style the close button.

1. Wireframe buttons

Wireframe buttons are often used in lightweight or flat style designs. The border, color, font, etc. of the button can be set through CSS styles.

The following is an implementation of a close button using wireframe style:

关闭

We added a class name named

to style the button. The following is the corresponding CSS code:

.close-button {
  border: 1px solid #999;
  color: #999;
  font-size: 14px;
  padding: 6px 12px;
  border-radius: 4px;
  cursor: pointer;
  background-color: transparent;
  transition: all .3s ease-in-out;
}

.close-button:hover {
  background-color: #999;
  color: #fff;
}

2. Button icon

In addition to using Text descriptions, buttons can also express functions through icons. Below we will combine the font icons and custom pictures introduced previously to implement the close button with icons.

Notice that here we have added a new class name

, and also set the class name of the button embedded element ifas fa -times means using the times icon. The following is the corresponding style code:

.close-icon-button {
  border: none;
  padding: 0;
  background-color: transparent;
  cursor: pointer;
  transition: all .3s ease-in-out;
}

.close-icon-button:hover {
  transform: rotate(45deg);
}

.close-icon-button i {
  color: #999;
  font-size: 14px;
  transition: all .3s ease-in-out;
}

.close-icon-button:hover i {
  color: #fff;
}

The above code implements the following button style:

4. Different types of application scenarios The close button

There are many types of close buttons, and choosing different types of close buttons should be based on the needs of the actual application. This section will introduce the close button under several common needs.

1. The close button on the modal box

The modal box is a pop-up window that is widely used in web pages. At the same time, the modal box needs a close button to close the pop-up window.

Generally, the close button of the modal box should be placed in the upper right corner of the modal box. The specific implementation is as follows:

Notice here that we have added a function called

JavaScript function used to close the modal box. The following is the corresponding style code:

.modal {
  position: fixed;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  width: 400px;
  height: 300px;
  background-color: #fff;
  box-shadow: 0 0 10px rgba(0, 0, 0, .3);
}

.modal button {
  position: absolute;
  top: 10px;
  right: 10px;
}

2. Multiple The close button of the tab page

  width: 16px;
  height: 16px;
}

The above code achieves the following tab page effect:
