is like this. The page layout of all browsers except safari is normal, like the following
. 
safari
is added later, and it needs to be judged to decide whether to display it or not. It is written in two forms, and its style is
.element.style {
width: 320px;
list-style: none;
float: right;
display: block;
}
* * but without refreshing, closing and opening, the layout of the form form returns to its normal state.
what I"m sure is that this should be the problem with safari browsers. After all, all other browsers are normal, but why can"t you open it for the first time? close it and then open it (no other operations, such as clearing cache, etc.). Ask the boss for help. * *
