How to resize img src in HTML <style>?

Here I am:

 h1 {
    color: orangered;
   font-family: rockwell;
  img {
    size: 80px;
flex-fit: (50%);
self-justify: center;
 <img src=""

Thanks… I will have a look on this Responsive Web Design curriculum again.

There are no such properties. For what you have as flex-fit you may be thinking of flex-basis, or at least that is a property that would let you set a presentage value. For self-justify you may be thinking of justify-self, however that doesn’t work with flexbox, only align-self works with flexbox.
