Is it possible to make a width of 5000px responsive?

I have floated the images to the left but wanted to make this stroke of images responsive? Like turning the 5000px into 100% or something like that.

no px is not responsive. thats why you have 100% or vw or ‘rem’.
there is aother overcome for this px no responsive problem which is @media of css
you can search for it its really easy to learn

Have you tried using flexbox? Learning it is one of the best things I’ve done to improve my CSS. Here’s a free course that is more current than the one I used: Learn Flexbox for Free
