CSS | User Interface

User Interface (UI) defines the way humans interact with the information systems. In Layman’s term, User Interface (UI) is a series of pages, screens, buttons, forms and other visual elements that are used to interact with the device. Every app and every website has a user interface.
The user interface property is used to change any element into one of several standard user interface elements. In this article we will discuss the following user interface property:

  • resize
  • outline-offset

resize Property: The resize property is used to resize a box by user. This property does not apply to inline elements or block elements where overflow is visible. In this property, overflow must be set to “scroll”, “auto”, or “hidden”.

Syntax:

resize: horizontal|vertical|both;
  • horizontal: This property is used to resize the width of the element.

    Syntax:



    resize: horizontal;

    Example:

    filter_none

    edit
    close

    play_arrow

    link
    brightness_4
