问题 EDIT: Embarrassingly, I originally saw this issue on Chrome but the issue was because I was slightly zoomed out on the browser causing subpixel element sizing. If the elements are full pixel heights it works fine. However, I believe this is still an issue as Firefox seems to render sub-pixel elements differently to Chrome and also we should support zooming. I'm trying to implement scroll-anchoring cross-browser so that when appending a new element to an overflow container and the user is

问题 I'm using scroll-snap in combination to position: sticky which seemed like an elegant approach to enable a stacking card effect while scrolling. It works pretty great on desktop but on Safari (iOS12.1) I'm experiencing glitches where sometime the cards scroll all together, skipping content. The most obvious way to replicate the bug on mobile Safari is to: scroll down to the bottommost screen close (blur) and reopen Safari then trying to scroll back up again Bug experienced: it's skipping all

问题 here i have my simple slider which i am theoretically going to use to control a stepper motor's movement based on the slider position. I wanted to make the website that it will be hosted on look professional so i have spent a long time trying to figure out how to change the button colour while it scrolls (this is because the motor is controlling my boiler temp so a visual representation of temp would be nice) but my problem is changing the css value. I know to use document.getElementById(

问题 I have a problem with removing cloned div. I*m unable to remove the cloned div which div clicked on to be remove. My code is like below: <div id="item_details"> <table> <tr> <td> <p class="label_text">Name:</p> </td> <td> <input name="item_name[]" type="text" value="" id="item_name" class="input_text" style="width: 126px;" /> </td> <td> <p class="label_text">Brand:</p> </td> <td> <input name="item_brand[]" type="text" value="" id="item_brand" class="input_text" style="width: 126px;" /> </td>

问题 I have a menu that I would like to fade in with javascript. I want it to transition from display: none and opacity: 0 to display: flex and opacity: 1 . But when I set opacity to 1 using javascript, it doesn't transition, and instead abruptly snaps to 1, whereas If I do not set display to none, it gracefully transitions. I want to use display: none because before the menu appears I need to be able to catch mouse movement on a canvas in the background. I have made a codepen to demonstrate this

问题 I'm using CSS animations (from animate.css) in a project I'm working on. What I found out is that when fading in a container with an absolutely positioned and z-indexed child in it, the z-index of the child isn't working as it should. I recreated the issue in this fiddle: http://jsfiddle.net/Lxsf9ako/ The issue seems to be caused by animation-fill-mode: both; This style is placed on the container by animate.css, thus I have no control over this. I could overwrite it by using animation-fill
