When I run the above code and open it in a new page, and inspect it to view it on a smaller device, the code works fine and the box's width is set perfectly.

However on my end, I have that above code embedded in my website, and so when I inspect my website and view it on a smaller screen. I get this output:

Why is that happening? I want the box to appear exactly as it is seen in the above code when you inspect it to view on a smaller device. Any suggestions?

Expected Output:

P.S. Please ignore the black lines on the box, just for the purpose of this question, I did not include the JS that handles the black lines
