hasCssOverflow.ts
const hasCssOverflow = (ele: HTMLElement) => ["auto", "scroll"].includes(window.getComputedStyle(ele)["overflow"]);The
`hasCssOverflow` function checks if an HTML element has CSS overflow. First, it gets the element's computed styles using `window.getComputedStyle`. This method returns an object with all the CSS properties applied to the element.Next, we check the
`overflow` property of this object and see if it's either `auto` or `scroll`. If it is, we know the element has CSS overflow and return `true`.If neither of these values is present in the
`overflow` property, we know there's no CSS overflow on the element and return `false`.#See also
