By default, Safari browser on Apple devices (iPhone, iPad, iPod, MacBook) will round the HTML input elements such as text box, buttons, combo box, and textarea. This could ruin your website layout especially when you use a stylized elements.

In order to turn off/disable/prevent the element rounded corners, you need to place these CSS codes:

input, textarea, select{
    -webkit-appearance: none;
    -webkit-border-radius: 0;
    border-radius: 0;
}
