Bulma - File
Description
It is used to upload files from user data by using the .file element in the input tag. The .file element is a main container, which includes below sub elements −
.file-label − It is considered as clickable part of the element.
.file-input − It is hidden for some styling purposes.
.file-cta − It calls the uploading process.
.file-icon − It specifies the upload icon.
.file-label − It defines the text for file label.
.file-name − It returns the name of the chosen file.
Let's create a simple example for file upload by using above sub elements as shown below −
<!DOCTYPE html>
<html>
<head>
<meta charset = "utf-8">
<meta name = "viewport" content = "width = device-width, initial-scale = 1">
