Premise: In html5 increasingly popular today, h5 application direction is becoming wider and wider, but sometimes we display on ios when the input click and selected will have a default highlight, which is a matter of global impact, set outline: None; border: none; But the discovery still has this kind of problem, after checking the information has the following solution
input{
-webkit-tap-highlight-color: rgba(255, 255, 255, 0);
-webkit-user-select: none;
-moz-user-focus: none;
-moz-user-select: none;
-webkit-appearance:none;
outline: none;
border: none;
}
