The CSS display
property is crucial for controlling how elements are displayed on a web page. It determines the layout and visibility of elements, influencing how they interact with each other.
Syntax
selector { display: value; }
Common display
Values
- block: The element is displayed as a block-level element. It starts on a new line and takes up the full width available.
div { display: block; }
- inline: The element is displayed as an inline element, which means it does not start on a new line and only takes up as much width as necessary.
span { display: inline; }
- inline-block: Like
inline
, but allows setting width and height.button { display: inline-block; }
- none: The element is not displayed on the page at all (hidden).
p { display: none; }
- flex: The element behaves as a flex container, allowing its children to align and distribute space dynamically. Flexbox is highly useful for creating responsive layouts.
.container { display: flex; justify-content: space-between; /* Distributes space between flex items */ }
- grid:
display: grid
turns an element into a grid container. CSS Grid allows you to define rows and columns and place items into them. It provides powerful layout control over a two-dimensional space (both horizontally and vertically)..grid-container { display: grid; grid-template-columns: repeat(3, 1fr); /* Creates 3 equal columns */ }
- inline-flex: Similar to
flex
, but displayed as an inline element. This is useful when you want the behavior of a flexbox but still want the element to align inline with other content..inline-flex-container { display: inline-flex; align-items: center; }
- inline-grid:
display: inline-grid
is similar toinline-flex
, but it makes the element behave like an inline element while also being a grid container..inline-grid-container { display: inline-grid; grid-template-columns: 1fr 1fr; }
- table: The element behaves like a table.
.table { display: table; }

Tips for Using display
- Understanding Layout: Knowing the difference between block and inline elements helps manage layout and spacing.
- Visibility vs. Display: Use
display: none
to completely hide an element, as it removes it from the document flow, unlikevisibility: hidden
, which hides the element but keeps the space occupied. - Advanced Layouts: Use
flex
andgrid
for creating complex layouts that are responsive and flexible.
By mastering the display
property, you can significantly control the layout and presentation of elements on a webpage, making it a fundamental concept for web design and development.
