您可能已經(jīng)注意到具有獨(dú)特滾動條的網(wǎng)站，這些網(wǎng)站賦予它們獨(dú)特的感覺和外觀，因?yàn)樽远x滾動條變得越來越普遍。自定義滾動條可以通過幾種不同的方式簡單地實(shí)現(xiàn)。本文將使用最簡單的方法，即 CSS。
我們使用 CSS 來增強(qiáng)應(yīng)用程序中網(wǎng)頁的視覺吸引力。使用 CSS，我們現(xiàn)在可以更改滾動條的外觀。讓我們看看如何使?jié)L動條自定義箭頭在移動設(shè)備上工作。
使?jié)L動條自定義箭頭在移動設(shè)備上工作
過去，網(wǎng)站上的滾動條可以使用非標(biāo)準(zhǔn) CSS 屬性（如scrollbar-base-color）進(jìn)行修改，您可以將其應(yīng)用于滾動的元素（如 ）并做一些非常棒的事情。 IE 放棄了這一點(diǎn)。
自定義滾動條今天再次可用，盡管這次使用了 WebKit。這些屬性現(xiàn)在使用“Shadow DOM”并且?guī)в泄?yīng)商前綴（例如：-webkit-scrollbar）。這已經(jīng)存在了一段時間了。
為了獲得有關(guān)使?jié)L動條自定義箭頭在移動設(shè)備上工作的更多想法，讓我們看看以下示例。
示例
在下面的示例中，我們使用 webkit-scrollbar 使?jié)L動條在移動設(shè)備上工作并將 CSS 應(yīng)用于滾動條。

Tutorials Point originated from the idea that there exists a class of readers
who respond better to online content and prefer to learn new skills at their
own pace from the comforts of their drawing rooms.The journey commenced with
a single tutorial on HTML in 2006 and elated by the response it generated, we
worked our way to adding fresh tutorials to our repository which now proudly
flaunts a wealth of tutorials and allied articles on topics ranging from programming
languages to web designing to academics and much more.
