My image-generating algorithm produces images of various sizes, some tall and some wide. How can I ensure that the images always fit perfectly within their parent container? They should be 100% height if they are tall and 100% width if they are wide.
.image-container{
width: 75rem;
height: 50rem;
}
/**I need a solution that actually works**/
img{
max-width:100%;
max-height:100%;
}
Before determining whether to make the height or width of your images 100%, you'll need a bit of JavaScript to check their orientation (landscape or portrait).
window.onload = function() {
let images = document.querySelectorAll("img");
for ( let i = 0; i < images.length; i++ ) {
images[i].width <= images[i].height ? images[i].style.height = "100%" : images[i].style.width = "100%";
}
}.image-container {
height: 300px;
width: 500px;
overflow: hidden;
background: floralwhite;
border: 2px solid silver;
margin-bottom: 2em;
}<div class="image-container">
