Bulma File Variables
Bulma is a free, open-source CSS framework based on Flexbox. It is component rich, compatible, and well documented. It is highly responsive in nature. It uses classes to implement its design.
The file element is used to upload custom file input. The ‘file’ component comprises several sub-elements that we have to add exclusively to design our content well.
These elements are listed below.
- file-label: It is the actual interactive and clickable part of the file element.
- file-input: It is the native file input, hidden for styling purposes.
- file-cta: It is the upload call-to-action.
- file-icon: It is an optional upload icon.
- file-label: It is the “Choose a file…” text
- file-name: It is the container for the chosen file name.
