QUESTION
I like very much css grid because of its simplicity. But there seems to be a performance issue with css grid that flexbox does not have.
I have implemented a two column full screen page both columns having a form with input box and a list of items with overflow-y:auto. One example where the left and right panel are implemented using flexbox and one where left and right panel are implemented with css grid.
this is the flexbox version : https://web-platform-wtfgmj.stackblitz.io/
and this is the css grid version : https://web-platform-wtfgmj.stackblitz.io/index2.html
Open the developper tools in chrome and enable paint flashing (tools/rendering has to be enabled). When typing in one of the input boxes, the css grid version will repaint all items in the list. The flexbox version does not have this problem.
I would like to understand why css grid repaints all items in the list when typing in the input box ? And can it somehow be avoided ?
Update : Seems to be problem with stackblitz... included as code snippets
Update 2: because it's little bit burried in comments: So I filed a bug report with chrome (bugs.chromium.org/p/chromium/issues/detail?id=1204446, upon suggestion of dgrogan) and they seem to confirm that it is a performance issue with chrome's current grid implementation. Apparently they are busy with a new implementation LayoutNGGrid which would solve the issue
...ANSWER
Answered 2021-Apr-27 at 16:36I've been able to reproduce the problem locally (almost at least). As you can see in the following image, in my browser (Chromium v92.0.4488.0) only an area on the far right of the column is repainted - exactly the area where the scrollbar will be displayed when it is used.
Using Firefox (v88.0) or Safari (v14.0.3), on the other hand, neither in the Flexbox nor the grid example anything other than the input is being repainted.
Since you don't use absolute values for the height of the containers, I suspect it happens due to the calculation of the height and whether the scrollbar needs to be displayed. Chrome seems to behave differently here than other browsers.
A simple fix seems to be to define an absolute height for the containers (vh, although it's a relative unit, seems to work too):

QUESTION
I have a list in React where I'm using .map to render a loop from an array of elements.
The radio inputs are working perfectly, everyone is independent of the others, but I can't do the same for Select.
The Select area is changing in every field, I want it to change to it specified field like I did for the options.
I tried to re-use the same handleChange that I used in the radios for it and instead I had this error.
ANSWER
Answered 2021-Apr-14 at 02:28Multiple Selects share the same state, resulting in updates the value on every field. So we need to wrap Select into components and maintain their own state independently：
QUESTION
I have a simple list where I have radio inputs for each element. They behave separately meaning that each selection changes the state of that specific element.

ANSWER
Answered 2021-Apr-12 at 23:22The problem is that your initial state is a string and you are using as a object in the handleChangeSelected
Just edit it to const [Selected, setSelected] = useState({});
Another tips:
- Try not to use capitalized names for variable that isn't a component
- Your list couldn't be a state
- Your id could be the index of the array
QUESTION
I have a simple list where in each li there is radio inputs to choose from.
Whenever I select an option, all the inputs in all the other elements are updating with the same option.
I included a unique id and a unique name as mentionned in React docs to regroup each group and make it separate but it didn't work.
I want to be able to select every element separately in the list. How to do so ?

I am trying to implement a photo gallery on this page:
...ANSWER
Answered 2021-Apr-06 at 02:55If you want to achieve that without setting a specific top and left value to center an image.
You have to add a position: relative on the parent container.
Then change the top and left attribute of .thumbnail:hover span to 0, and also add a right: 0. To center your absolute positioned div (which is the enlarged image), add margin: 0 auto. And lastly set that element's width to max-content.

QUESTION
how can i start process consumers from code for cpu bound tasks ?
And how can i get signal callbacks without immediate ? If i run MemoryHuey with immediate=True all works fine but if i set it to False i get only empty lists.
Problem:
I have several endpoints which have to be processed with different priorities. The processes are all CPU intensive and have to be moved to the background and processed using multiprocessing. A Redis cluster is later used as job storage.
Thanks :) PS: ignore async
Edit: Or is there an easy solution to run with supervisor in AWS EB ?
...ANSWER
Answered 2021-Mar-10 at 14:40You are trying to share memory across processes which isn't going to work. Each process has its own copy of the memory - this is why you need to use a broker like Redis, Sqlite or the file-system when you are using multiprocess huey.
