I used this code in my CSS file that included to my page, but some times appear in different appearance. For example, color is white, but in some of the android devices render in red!
input[type="checkbox"]:checked::after{
position: relative !important;
content: '✔' !important;
display: inline-block !important;
font-size: 19px !important;
margin: -9px 1px !important;
color: #fff !important;
vertical-align: top !important;
font-weight: normal !important;
font-family: Yekan !important;
z-index: 0;
}
What is the problem?
