My goal is to incorporate color-switch buttons on my webpage. When these buttons are clicked, I want the existing colors to change to different shades. However, my challenge lies in the fact that these colors are used for various elements such as backgrounds, borders, and font colors. Is there a way to use jQuery to identify the exact color being used and modify it consistently throughout the page? Any assistance would be greatly appreciated.
To fulfill your specific needs, it might require a bit of trial and error. One suggestion is to assign a class to the elements you wish to modify all at once. For instance, you could designate class = "colorChange" and then create two buttons - one for switching everything to blue, and the other to red.
Button HTML code:
<button id="blue">BLUE</button>
<button id="red">RED</button>
Javascript functionality:
$('#blue').on('click', function () {
$('.colorChange').css({
'background-color': 'blue',
'color': 'blue'
});
});
$('#red').on('click', function () {
$('.colorChange').css({
'background-color': 'red',
'color': 'red'
});
});

If you need to verify the current color, you can use
$('.colorChange').css('background-color')Check out this interesting code snippet that can dynamically change the color of all black elements on your webpage:
var sourceColors = ["black", "#000000", "#000", "rgb(0,0,0)"];
var targetColor = "orange";
var elements = document.querySelectorAll("*");
for (var i = 0 ; i < elements.length ; i++) {
var e = elements[i];
if (sourceColors.includes(e.style.color)) {
e.style.color = targetColor;
}
}
This may not be the most efficient solution, but it gets the job done - give it a try!
