jQuery text alignment breaking bug

I am attempting to create an overlay for a couple of my divs to prevent users from progressing without completing previous tasks. The overlay is functioning correctly and the message is displaying, but I encounter issues when trying to center the message.

Here is my jQuery code:

$("<div>You must finish your previous tasks before moving on.</div>").css({
    position: "absolute",
    width: "100%",
    height: "100%",
    top: 0,
    left: 0,
    background: "rgba(0,0,0,0.3)"
}).appendTo($(".disabled-box").css("position", "relative"));

As soon as I add 

   text-align: "center"

it causes an error:

SyntaxError: Unexpected token '-'

Do you have any insights into why this might be happening?

Answer №1

It is important to update your code as follows:

$("<div>You must first finish your previous tasks before proceeding.</div>").css({
    position: "fixed",
    width: "100%",
    height: "100%",
    top: 0,
    left: 0,
    background: "rgba(0,0,0,0.3)",
    textAlign: 'center'
}).appendTo($(".disabled-box").css("position", "absolute"));

In JavaScript, when referring to styles, remember to use camelCase instead of dashes.

Answer №2

Insert it in this manner:

$("<div>Make sure to finish your current tasks before proceeding.</div>").css({
    position: "fixed",
    width: "100%",
    height: "100%",
    top: 0,
    left: 0,
    background-color: "rgba(0,0,0,0.3)",
    textAlign: "center"
}).appendTo($(".disabled-container").css("position", "absolute"));

Answer №3

There are multiple ways to align text in CSS:

textAlign: "center"

Or you could also use:

"text-align": "center"

Both methods will achieve the same result, so it's a matter of personal preference.

I prefer to maintain consistency in my code by choosing one method and sticking with it.

Answer №4

Consider using the CSS property position: "fixed" and adjusting the margins to achieve a static display of your dialog on screen. I personally use this technique for my own messages quite frequently.

Instead of implementing it in JQuery, you could create a class named center for your div which will simplify your code.

.center{margin:0 0;width:100%;height:100%;top:0px;left:0px;position:fixed;background-color:#FAFAFA;overflow:hidden;opacity:0.9;z-index:99;}

I hope this suggestion proves useful to you.
