Screenshot on mobile

I want to make a responsive web application, but mobile window isn't filled with the image, and I don't know how to edit the code to make it. I assume that I have to embed the code targeted with mobile web, but I don't know how to do. I attach the image file to explain my situation. Please help.

CodePudding user response：

You can try to put in the css of your container:

width:100%;
height: 100%;

And in the css of your pictures :

width:100%;
height: undefined;
// figure out your image aspect ratio
aspectRatio: 50 / 32;

CodePudding user response：

Add css with media query

@media(max-width:480px) {
img {
    width:100% !important;
    height: 100% !important;
    object-fit: cover; }
}
