css

问题 Please see an example in jsfiddle. https://jsfiddle.net/0uwmxt02/1/ In IE and EDGE the transform: translateY(-50%) causes 1px jump up and down at the start and end of the animation. In Chrome the displacement still occurs but it is smooth. Any idea of what causes it? .submenu-arrow-hover { position: relative; width: 200px; top:50px; } .submenu-arrow-hover:after { //background: rgba(155, 173, 188, 0.9); position:absolute; content:''; width: 1px; height: 28px; border: 1px solid red; border

问题 I have the below code example (taken from here) . Is there a way for the below to work without hardcoding the values "a" and "b" in the html css?

This is the js which is being used : var tSwitcher = document.getElementById('theme-switcher'); let element = document.body; let onpageLoad = localStorage.getItem("theme") || ""; if(onpageLoad

问题 I've got a bunch of tabbed divs on a page for each day of the week, which are being shown/hidden with jQuery when clicked. The class "first", added manually to whatever tab I want, tells the page which div to show when the user first lands there. At the moment it is set to the Monday div. How would I go about setting this up so that jQuery can add the class dynamically to the actual current day's div instead of hard coding it? Divs are set up like this (with Monday being currently selected):
