I have been struggling for the past few hours with a positioning problem. I have been following a basic tutorial on how to compose an image gallery from w3c: How to Create a Tabbed Image Gallery I am using bootstrap's grid system for layout, and I have been very careful not to use bootstraps class names where it might interfere with those provided in the tutorial. The reason is that I see myself using bootstrap for layout, but I want to be able to customize things, as well. Basically, there is a div tag with the class title "mycontainer" with display set to none, which is then set to display: block in the javascript section. That part works just fine. The problem is that the tutorial includes this little X, using the html code × I will include the full code below. The × is supposed to be an X-out for the image, which is enlarged when a user selects one of several top images (here is a picture of it). I circled the xelement The problem is that no matter what I do, I cannot seem to control the positioning of that X. I have tried inline style, to no avail. I tried doing it exactly as the tutorial recommended, which was to use a css class to position, but with that I wasn't even able to control the coloring. At least with inline styles, I was able to color the element. But padding-left, margin-left, text-align:center. I tried separately and all at once. None of these work, and I just simply cannot figure this out. Here is the javascript, which is included in the section. Thanks a million times for your time.

In a tab gallery as described here I have added individual title above and content under the expanded images with the following code, which I am sure can be simplified (going with the DRY rule :-) ), right?

The aim is in one sentence: When I click on #column1 show #imgcontent1 and .title1 and hide all the others, and so on for every #column.

I have set up a gallery like this one by W3Schools but with jquery instead of javascript as shown here.

I have a problem with a modification, maybe someone can help: I added mousover titles using the images alt tag to the thumbnails using the following code:

I need to draw a two-dimensional grid of Squares with centered Text on them onto a (transparent) PNG file. The tiles need to have a sufficiently big resolution, so that the text does not get pixaleted to much.

For testing purposes I create a 2048x2048px 32-bit (transparency) PNG Image with 128x128px tiles like for example that one:

The problem is I need to do this with reasonable performance. All methods I have tried so far took more than 100ms to complete, while I would need this to be at a max < 10ms. Apart from that I would need the program generating these images to be Cross-Platform and support WebAssembly (but even if you have for example an idea how to do this using posix threads, etc. I would gladly take that as a starting point, too).

When I try to run my code in PyCharm, it exits with code 0, and gives the desired output, but when I try to run it in VS Code it gives the File "c:\Users\1\Desktop\ImagetoText\ITT2.py", line 21, in img = cv.cvtColor(img, cv.COLOR_BGR2RGB) cv2.error: OpenCV(4.5.1) C:\Users\appveyor\AppData\Local\Temp\1\pip-req-build-kh7iq4w7\opencv\modules\imgproc\src\color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cv::cvtColor' error.

How it is possible that the same code runs without errors or warnings relating to this line in PyCharm while not working in VS Code or directly in W10 is alien to my understanding.

Note: I have tried tweaking the path but to no avail.

Code:

I simply can't seem to find the bug here? Why does the following code give me a "Cant perform react state update on an unmounted component"?

I have an array I'm mapping into image sources to form an image gallery. At the moment it maps down one column. I'm unsure how to make it fill the other columns. Any tips would be much appreciated!

This is current output

I have successfully built a python server which even works but when java from android studio tries to connect to it fails with whole bunch of errors. I have understood that it fails while creating a new socket object but why that I don't know.

This is Java client, see at the end of the code particularly for the issue where I have created new Socket object:

I want to increase the opacity to 1 for img__text when the user hovers over text__container. I have tried achieving this with strictly CSS by trying to effect the child of text__container like so, #text__container ~ .img__text then applying the desired CSS effects.
