What is the best way to switch text color when the background changes?

Is there a way to dynamically change the color of a text logo to make it readable over differently colored backgrounds, such as on a slider or scroll down effect? While one approach could involve finding the dominant image color, this may be slow and inefficient. Are there any alternative methods?

Some interesting examples I've come across:

  • (Watch for the color change in the image)

Would the most effective way to achieve this effect on a slider be to create an array of colors corresponding to each slide?

Answer №1

Google Home operates by altering the class of the main div when the slider changes, allowing for a corresponding change in text color. The predefined text color is derived from the image color, which simplifies customization and minimizes calculation needs. This approach offers an efficient and adaptable solution for your specific situation.

Answer №2

I'm not entirely sure what you're asking, but if you want to modify the HTML structure when the user scrolls to the bottom of the page, you'll need to write some JavaScript code for the jQuery scroll event.

$(document).scroll(function(){
if($(window).scrollTop() + $(window).height() >= $(document).height()) { //if user has reached the bottom of the page
   //insert your code here
}
});

Answer №3

$(document).ready(function(){       
    var scroll_pos = 0;
    $(document).scroll(function() { 
        scroll_pos = $(this).scrollTop();
        if(scroll_pos > 210) {
            $("body").css('background-color', 'blue');
        } else {
            $("body").css('background-color', 'red');
        }
    });
});
