How to Take Advantage Of the Fullscreen API … and Design It

Let’s take a look at the Fullscreen API in JavaScript. It permits you to do a quite effective thing: complete screening precisely one specific component you desire it to. Not just that, however CSS can assist too with an unique selector.

Every significant web browser has integrated fullscreen performance in the type of taking full advantage of the web browser window itself. You push F11 or ⌃ ⌘ F (WinKey ⬆ on PC) and the internet browser will fill your display, reaching eliminating UI elements (like the window management buttons).

When you enter into fullscreen mode, it takes full advantage of the area for a websites to show, however this isn’t constantly precisely what you desire. Regularly, you either wish to fullscreen some specific aspect of the page, for instance, a video game or a video. This is where Fullscreen API is available in helpful.

After that, the only thing is to inspect if that aspect has the requestFullscreen() approach, and after that call it on the component. Let’s begin with a basic< div > aspect to fullscreen:< pre rel=" HTML" class =" wp-block-csstricks-code-block language-markup" data-line >< div id=" fullscreen" >

    First, we’ll pick it and inspect if it has the approach. We call the requestFullscreen if it does approach on it. It’s that simple: < We desire to run this code conditionally and not as quickly as somebody someone on the page. We'll make a button that toggles fullscreen mode.< pre rel => “HTML” class=” wp-block-csstricks-code-block language-markup” data-line >< div id =" fullscreen" >< button id=" button" > Toggle Fullscreen. < pre rel=" JavaScript" class=" wp-block-csstricks-code-block language-javascript"

    data-line > let fullscreen= document.querySelector(" #fullscreen");. let button= document.querySelector("#button”); button.addEventListener (” click “, ()= > p>

    ); Notification how we’re utilizing document.fullscreenElement. If there is a component that has actually been fullscreen previously, then it will return it; if not, it will return null. If fullscreen mode was even allowed in the user’s internet browser at all, it’s likewise a great concept to inspect. For that, we can utilize document.fullscreenEnabled. It returns a boolean stating whether we can utilize the Fullscreen API in this specific web browser. Fullscreen might be disabled by the user, or the web browser

    may not support it. The last approach that we will cover is document.exitFullscreen(). A user must constantly have the capability to leave fullscreen mode by pushing ESC on the keyboard. We might do some sort of customized method to leave fullscreen mode utilizing exitFullscreen. It does not matter what component was fullscreen; it will return to window mode after calling this approach.

    As you can see in the code for our button aspect, we initially examine if fullscreen has actually currently been triggered. Based on that details, we either go to fullscreen mode or we go back to window mode.

That’s precisely what the: fullscreen

    pseudo-selector is created to do!< pre rel=" CSS" class=" wp-block-csstricks-code-block language-css" data-line >

    #fullscreen: fullscreen background-color: yellow;.< img loading=" lazy" width =" 2374" height= "1654" src= "" alt class =" wp-image-337537 "> As you can see, the #fullscreen div is the only component that gets a yellow background color when the component remains in fullscreen mode, and just in fullscreen mode. The catch is that we ca n't in fact choose any component like this; we can just choose the root component tha t's in fullscreen mode. None of the kid aspects will match.

    Simply put, something like #button: fullscreen will not choose a button that is included within the fullscreen aspect-- that is, unless we desire the button to be fullscreen rather of the div.

    Some web browsers need a prefix for this to work. Firefox utilizes - moz-full-screen and WebKit-based internet browsers utilize - webkit-full-screen.

    < pre rel=" CSS" class=" wp-block-csstricks-code-block language-css "data-line > #fullscreen:- webkit-full-screen #fullscreen 

    :- moz-full-screen Did you understand that when we remain in fullscreen mode that there is a pseudo-element that is rendered right listed below your fullscreen aspect? By default that pseudo-element is black. If you wish to alter the designs of that pseudo-element you can do it like this:

    < pre rel=" CSS" class=" wp-block-csstricks-code-block language-css" data-line > #fullscreen:: background 

    Here's the last example. Fullscreen mode may not work with ingrained Pens, so you will require to see it outside this short article.
