Behavior of Replaced Elements with Different Display Values in CSS
Replaced elements, such as <img>, <input>, <textarea>, <video>, and <iframe>, have intrinsic dimensions and content that are replaced by external sources or browser-defined rendering. Their behavior with display depends on the CSS property applied.
By default, most replaced elements behave like
inline-block, allowing width and height to be set while flowing inline with text.display: blockmakes replaced elements start on a new line and take up the full width of their container (unless width is specified).display: inlinekeeps replaced elements in the text flow, but height and width may be ignored depending on the element and browser.display: inline-blockallows replaced elements to remain inline while respecting width and height.Replaced elements respect
marginandpaddingdifferently depending on the display value and the browser’s layout rules.
In this example, the first image flows inline with text, the second image appears on its own line as a block, and the input remains inline but respects its specified width.
Use
inline-blockfor replaced elements when you need them inline but still want control over width and height.Use
blockwhen you want replaced elements to occupy their own line and control layout structure.Test across browsers, as some replaced elements may render slightly differently depending on default styles.
