If you're looking to implement a specific functionality that is not natively supported by browsers, there's a clever workaround that can achieve the desired result:
::-webkit-input-placeholder { /* Chrome/Opera/Safari */
color: transparent;
}
::-moz-placeholder { /* Firefox 19+ */
color: transparent;
}
:-ms-input-placeholder { /* IE 10+ */
color: transparent;
}
:-moz-placeholder { /* Firefox 18- */
color: transparent;
}
:hover::-webkit-input-placeholder { /* Chrome/Opera/Safari */
color: #999;
}
:hover::-moz-placeholder { /* Firefox 19+ */
color: #999;
}
:hover:-ms-input-placeholder { /* IE 10+ */
color: #999;
}
:hover:-moz-placeholder { /* Firefox 18- */
color: #999;
}<input type="text" placeholder="Enter your name" />It's also important to consider the compatibility with different browsers.
Here is a JavaScript solution that may meet your needs:
If you have a textbox with the id "input", you can use the following code:
let input = document.getElementById('input');
function addPlaceholder() {
input.setAttribute('placeholder', 'Enter your name');
};
function removePlaceholder() {
input.setAttribute('placeholder', '');
};
input.addEventListener("mouseover", addPlaceholder);
input.addEventListener("mouseout", removePlaceholder);
