Is it possible to alter a particular style using CSS or JavaScript?

Question

Is it possible to alter a particular style using CSS or JavaScript?

This question may be old, and similar ones that were solved are even more complex. Unfortunately, I have tried and failed to figure it out on my own.

Here is the scenario:

<div style="color:white; padding:10px">Text</div>

I am looking to change the color of the text from white to red:

div[style*="color:white"]{color:red}

$('div').filter(function() {
    return $(this).css('color') == 'white';
}).css("color", "red");

I have attempted both CSS and JavaScript solutions, with or without whitespace, and using either hex or RGB color codes.

Answer №1

One problem is the unexpected return value. Instead of 'white', it returns an RGB string as rgb(255, 255, 255). Adjust this to achieve the desired outcome.

When you use $(this).css('color'), it will give you the value rgb(255, 255, 255). You can take advantage of this by using the following code:

$('div').filter(function() {
    return $(this).css('color') == 'rgb(255, 255, 255)';
}).css("color", "red");

When referencing the .css() method in the JQuery API documentation, it mentions that different browsers may interpret CSS color values slightly differently - for example, #FFF, #ffffff, and rgb(255,255,255) are logically equivalent but not textually identical.

Therefore, a simple comparison like

return $(this).css('color') == 'rgb(255, 255, 255)';

might pose issues in the future.

My suggestion is to use CSS classes instead for implementation, like so:

.white{color:white;}
.red{color:red;}

$('div').filter(function() {
    return $(this).hasClass('white');
}).removeClass('white').addClass('red');

As for why

div[style*="color:white"]{color:red}

does not work, inline styles have the highest priority among the three ways of applying styles.

When it comes to CSS, inline styles always take precedence over any internal or external stylesheets. If you find yourself in a situation where you can remove the inline CSS from a specific element and replace it with something like

<div class="newElement"></div>

, that would be the preferred approach. Alternatively, if you choose to use jQuery, you can achieve the same result by utilizing the CSS method without filters:

$('div').css('color', 'green');

You seem to be getting a bit funky with the filter function there. It's not meant to be used in that way. If you want to select a DOM element and change its css using jQuery, try this $('div').css({'color': 'red'});
