What is the method for customizing the color of a placeholder text in a specific text field

Is there a way to style placeholder text in different colors for each text field?

According to the Mozilla documentation, the code snippet provided will change the color of the entire input tag.

If you'd like to learn more, follow this link: https://developer.mozilla.org/en/CSS/%3a-moz-placeholder

<style type="text/css">  
    input:-moz-placeholder {  
      color: green;  
    }  
</style> 

However, you mentioned wanting different colors for each text field.

HTML Example

<input id="foo" type="text" placeholder="I'm green" />
<input id="foo2" type="text" placeholder="I'm red" />

Using jQuery

You attempted to change the color of the placeholder text using the following code, but it only affected the input field itself, not the placeholder text.

var elementId = "#foo2";
$(elementId + ":-moz-placeholder").css("color", "red");

It seems like the selector may not be correct. How can you style individual placeholders by element ID using jQuery?

Answer №1

Did you happen to experiment with CSS classes?

<input class="blue" id="bar" type="text" placeholder="i'm blue" />
<input class="yellow" id="bar2" type="text" placeholder="i'm yellow" />

<style type="text/css">  
    input.blue:-moz-placeholder {  
      color: blue;  
    }  
</style> 

Answer №2

In the realm of web development, the :-moz-placeholder pseudo class plays a significant role.

It's crucial to note that pseudo classes do not belong to the Document Object Model, meaning that jQuery does not possess the capability to directly manipulate them.

One suggested method is to leverage classes for altering colors, as recommended by Walkerneo.

By incorporating Walkerneo's code, you can seamlessly transition the class from green to red using the following snippet:

$("input#foo").toggleClass('red').toggleClass('green');

Answer №3

You can use jQuery to add a custom style block at the beginning of the head section:

    var $customStyle = $("" +
            "<style id='custom-style'> " +
                ".custom-class {background-color: " + customColor + "; color: #fff;}" +
                ".button {background-color: " + customColor + "; color: #fff; border: 2px solid " + customColor + ";}" +
            "</style>"
        );

    $('head').prepend($customStyle);
