About the Add a Text Alternative to Images for Visually Impaired Accessibility Part on Safari

Tell us what’s happening:
I’m going through with the html/css tutorial these days. I find myself very happy doing it. it’s great and very easy understanding.
When I got to the part of Add a text alternative to images for visually impaired accessibility, I found an issue which is:
On Safari, the alt text will not show unless you set a width and height big enough for the image.
on Chrome the alt text will show directly after the image.
according to my investigation, this seem to be a characteristic of Safari.
maybe adding this kind of information to the text will be more helpful for safari user like me?
