vertical-center | 水平垂直居中，这是一道面试必考题，_

I thought I had everything covered, but I'm now having issues with flip boxes working on Mac. I was able to make them compatible with different browsers on phones. I had someone with a Mac say that they were having problems with the animation. I heard that they saw a weird blinking and can see the front of the card through the back. I'm not sure what I'm missing. The last time I had this issue was with iOS, but I was just missing one line of code. Any suggestions? Honestly, I'm winging this as I go and can use any guidance.

There are a lot of questions about vertical centering, the occasional flexbox-stretching oddity, or the difference between block and table elements, but I couldn't find anything about the (unexpected) behavior of this particular combination.

I'm in a bit of a tricky situation with the markup bootstrap-vue is giving me:

I don't really have any background of HTML or CSS. I've been figuring out how to change existing codes to help make sections of a website. The only issue is that I can't make it mobile-friendly. I made a code to create 8 flip boxes that work when you visit the website on a computer. However, they don't work so well on mobile. I don't really know what I'm doing, but is there anyway I can align the 8 boxes in one column for mobile use and use touch to make them flip? Thanks!

I'm trying to centralize the div "Status" using css. Already tryied to use vertical-align: middle, display: flex, align-item: center and nothing works. Can someone help me? it seens like the height of the div remains the same so I can't centralize it since it's content fills it's exactly entire space.

HTML

I'm trying to log in and then redirect to a custom page, based on user type. My problem is that when I'm pressing the login button, on the console I get that that I have a Undefined array key pageType, and I don't understand why... If I'm for example on teacher page, I set $_SESSION['pageType'] = 'teacher'; This my login.html page:

I am using the BootstrapTable component in React, I would like to know if someone knows how to switch what is inside a cell of a row on enter.

For example when I enter in a row, the Date cell of this row switch to icons instead of a text. here's what my tab looks like: here's what a would like to have (best I can do with my photoshop skills): Here's some of my code (it's a big code but the main part is here):
