Question

How can I create a really basic overlay in jQuery without UI?

What is a lightweight plugin?

Answer 1

Here is a simple javascript only solution

function displayOverlay(text) {
    $("
" + text + "
").css({
        "position": "fixed",
        "top": 0,
        "left": 0,
        "width": "100%",
        "height": "100%",
        "background-color": "rgba(0,0,0,.5)",
        "z-index": 10000,
        "vertical-align": "middle",
        "text-align": "center",
        "color": "#fff",
        "font-size": "30px",
        "font-weight": "bold",
        "cursor": "wait"
    }).appendTo("body");
}

function removeOverlay() {
    $("#overlay").remove();
}
