For instance, this will change as you scroll down a page on mobile, since the mobile URL bar moves out of your screen. Unit dvh reflects how much vertical viewport height the user agent's interface currently takes up.
This unit excludes the user agent's interface, unlike unit vh, and updates as the current viewport height changes. Unit dvh reflects the current viewport height. Unit lvh reflects the largest possible viewport height visible to the user. The smallest possible viewport height excludes all interface elements by the user agent.īy default, the vh unit includes the address bar that comes with a mobile browser. Unit svh reflects the smallest possible viewport height that is visible to the user. Overview of the new incoming CSS viewport units svh Just like is the case with unit vmin, unit vmax needs recalculation to subtract the scrollbar from the viewport width. Unit vmax refers to the largest dimension of the viewport. Just like is the case with unit vw, unit vmin needs recalculation to subtract the scrollbar from the viewport width. Unit vmin refers to the smallest dimension of the viewport. Consider reading the how-to section CSS 100vw minus scrollbar width.
That is the reason why web browser developers decided to keep the calculation of the vw unit as is. This means that a forced recalculation of styles would occur after the web browser finds out that a scrollbar has appeared due to rendered content overflowing the root. That means that the web browser can only know whether or not to subtract the scrollbar width if the whole web page has already rendered. Whether the scrollbar's width should be subtracted from vw or not depends on whether the web page has content that overflows the root vertically. Web browser developers have discussed this and decided not to subtract the scroll bar width from the vw unit. There has been frustration and debate about unit vw including the scrollbar that may or may not be present on the right side of your viewport, causing a horizontal scrollbar when applying 100vw on an HTML element inside of a scrollable web page. Unit vw refers to the width of the viewport.

Safari for iOS was one of the first mobile web browsers to change the value of the vh unit to refer to the largest possible viewport height.Ĭhrome for Android changed the implementation of unit vh accordingly in version 56. This caused layout shifts when, for instance, the address bar would move out of view due to scrolling down a web page.

Unit vh refers to the height of the viewport.īefore 2017, Chrome for Android would update the value of vh whenever the currently visible viewport height changed due to the interface of the browser changing.
This means that 50 vh is equal to 50% of the viewport's height. Note: all viewport-relative units hold a value that is relative to 1% of the dimension of the viewport it refers to. Overview of current viewport units (as of March 2022)īefore we jump into the new CSS viewport units, it's important to know the behaviour of the viewport units that are currently supported by most modern web browsers. This means that there has never been a clean or built-in solution for issues regarding viewport height excluding the interface of mobile viewports (the URL bar for instance). For developers this used to require both CSS and JavaScript. These new CSS units are there to better reflect the viewport's minimum, maximum and current dimensions. As of March 2022 new CSS viewport units svh, lvh, dvh, svw, lvw, and dvw are incoming as part of the efforts of Apple, Bocoup, Google, Igalia, Microsoft, and Mozilla to improve the web for developers as part of a project called Interop 2022.
