CSS place-self Property - askthedev.com

The CSS place-self property is an essential tool for controlling the alignment of items within a CSS Grid or Flexbox layout. It allows developers to specify how individual flex or grid items should be positioned along both the block (vertical) and inline (horizontal) axes. This property simplifies the process of aligning items, offering a convenient and efficient way to manage layout designs.

1. Definition of the place-self property

The place-self property combines the functionalities of two other properties: align-self and justify-self. It makes it easier for developers to set the alignment of a specific item without having to define each property separately, streamlining the CSS code.

2. Syntax

selector {
  place-self:  ;
}

Here, determines the alignment along the block axis, while handles the inline axis alignment.

3. Possible Values for the place-self Property

Value	Description

start	Aligns items to the start of the block or inline axis.
center	Centers items along the block or inline axis.
end	Aligns items to the end of the block or inline axis.
stretch	Stretches items to fill the available space along the block axis.

4. Default Value

The default value for the place-self property is auto. This means that if it is not explicitly set, the item will inherit the alignment of its parent container. This behavior allows for consistent alignment throughout the grid or flexbox without additional configurations.

5. Formal Definition
