Cross-browser Custom Styling for File Upload Button [duplicate]

Introduction:

Styling file upload buttons can be challenging due to browser-defined dimensions. Conventional approaches often involve JavaScript or Quirksmode's technique, which can have limitations. Here, we explore a more user-friendly and effective solution without the need for JavaScript.

Answer:

A simple and efficient method involves using the tag around a hidden file upload button.

HTML:

<label class="myLabel">
    <input type="file" required/>
    <span>My Label</span>
</label>

CSS:

label.myLabel input[type="file"] {
    position: absolute;
    top: -1000px;
}

/***** Example custom styling *****/
.myLabel {
    border: 2px solid #AAA;
    border-radius: 4px;
    padding: 2px 5px;
    margin: 2px;
    background: #DDD;
    display: inline-block;
}
.myLabel:hover {
    background: #CCC;
}
.myLabel:active {
    background: #CCF;
}
.myLabel :invalid + span {
    color: #A44;
}
.myLabel :valid + span {
    color: #4A4;
}

Benefits:
