memory-game | Best practice

I'm making a flip card game, but the check for matches function won't work. I'm also unsure if I should use

.dataset.framework

or

.dataset.name

for my checkForMatch() function. And since the checkForMatch() function will not work, I can't limit to opened cards to two (as in, I can just keep opening cards as much as I can, without the cards unflipping back to normally despite the fact that I've included unflip function).

I referred to this tutorial and this tutorial, since these are exactly how I want my code to turn out to be but nothing seems to be working.

I'm making flip card game, but the photo won't stay opened when I click on it. I've listed down what needs to be done in the JS, but can't seem to wrap my head around how I can implement them to my HTML file. The photos are supposed to appear randomly (like typical flipcard games), but when I try to add some other functions on the JS file, suddenly the random function that previously worked, no longer works.

Also, I'm supposed to use .card.open for the photo to stay open when I click them. But when I add this function to my CSS file, click function no longer works.

I have a code for a Memory game with images. I took the reference for the game from this link:

Memory game

In this code , the game has a clock/ timer. I would like to make this timer into a clock down timer setting a limit of 10 mins. I dont know how to change this timer into clock down time. Can someone help me out with this problem.

I'm working on a memory game for mobile and desktop. For flipping the cards I'm making use of 3D animation. The animation looks good on desktop, but when on mobile devices you need to scroll down in order to see the cards. But the further you scroll down the page the more 'distorted' the animation becomes. Here are some gifs visualizing the problem:

My code:

I've been selflearning a bit about Jscript and CSS playing with the code of this card memory game: https://marina-ferreira.github.io/projects/js/memory-game/

Which I have in codeopen here: https://codepen.io/jaimesoza/pen/xxwJBde

I would like to add some text (the name of the card) only to the flipped version, for obvious reasons. I've seen some examples which do that, but I have not been able to apply them to this current CSS, as I am a total noob in these matters. Every time I try something similar to this I end up messing everything.

So in my program, the buttonPanel.setSize does not seem to be working:

I am working on my first android-project, a memory-game in Android Studio. The gameActivity-Frame should contain some textViews, displayed in one line (for stats) on the top of the screen and the memory-cards below. There are mutliple memory-versions, so the number of memory-cards vary - and by that the dimension of thier GridLayout.

My main Layout is a LinearLayout (vertical). I placed another LinearLayout (horizontal) on it, where the Textviews take place. To display the cards, I used a GridLayout which will be filled with cards once the game started. The LinearLayout (with textViews) should always stick on the top of the screen. The GridLayout should be centered in the remaining space below.

What I get is that both Layouts either stick in the middle, or that the LinearLayout is correct, but the GridLayout is either on the bottom or on the top of the remaining space.

I tried to find a solution here on SO, and I think I tried every possible combination of the gravity- and layout_gravity - settings of the components. I can imagine the problem is that I can use either wrap_content or match_parent in the main Layout, but not both. Guess I'd need wrap_content to stick the first Layout to the top and match_parent to use the whole space below this Layout.

How can I stick the first Layout to the top and center the GridLayout in the remaining space?

The picture shows my current layout (see code below) and how I want it to look. center_GridLayout

Edit to clarify: The LinearLayout should stick to the top of the screen, the GridLayout should be centered in the remaining space below the LinearLayout. RelativeLayout won't do the job properly, because the layouts might overlap, depending on the amount of memory-cards and the user's device's dimensions. I uploaded another screenshot where it's better visible what I want to achieve:

This is my .xml (deleted some unimportant textViews):

I have created a custom element named memory-game and I am able to create lots of them by clicking on the icon of the memory game. I want functionality so that when I click on a memory-game window, it appears on top of the other opened windows. I can't figure out how to do that.

I'm using this example: QML Flipable Example. I created rectangles with GridLayout. I just added my new state the example:
