This is How to Dynamically Change Your Website's Menu and Social Media Colors Based on Background
As web designers and developers, we often spend a significant amount of time perfecting the visual aesthetics of a website, carefully selecting color schemes and ensuring that all design elements work in harmony. However, one challenge that can arise is maintaining optimal contrast and visibility as the background color changes – whether through user interaction, scrolling effects, or other dynamic elements.
Fortunately, there's a clever JavaScript technique that can help solve this problem by automatically adjusting the colors of your website's navigation menu and social media icons to ensure they remain readable and visually appealing no matter the background.
In this article, we'll dive into the code behind this dynamic color-changing functionality and provide a step-by-step guide to implementing it on your own website.
The Approach
The core idea behind this solution is to use JavaScript to continuously monitor the background color and adjust the menu and social media icon colors accordingly. This is achieved through the following steps:
-
Detect Background Color Changes: We'll use a setInterval function to regularly check the background color and detect any changes.
-
Calculate Appropriate Foreground Colors: Based on the current background color, we'll determine the appropriate foreground colors (menu text and social media icon colors) that will provide the best visibility and contrast.
-
Update the CSS Dynamically: Once we've calculated the optimal foreground colors, we'll update the CSS of the relevant elements to apply the new colors.
By implementing this approach, your website's menu and social media icons will seamlessly adapt to the changing background, ensuring a polished and visually consistent user experience.
The Code
Let's dive into the code and see how this dynamic color-changing functionality can be implemented.
var cursor = 0;
var direction = -1;
var fps = 15; // frames per second
// -0.25 ... 0 ... 0.25
// ^
// cursor
setInterval(function () {
cursor += direction * 0.01;
if (Math.abs(cursor) > 0.25) direction *= -1;
document.body.style.background = makeGradient(cursor);
updateMenuAndSocialColors(cursor);
}, 1000 / fps);
function makeGradient(cursor) {
var p1 = Math.round(cursor * 100);
var p2 = Math.round((cursor + 1) * 100);
return "linear-gradient(45deg, #ff2200 " + p1 + "%, #23548b " + p2 + "%)";
}
function updateMenuAndSocialColors(cursor) {
var menuColor = getContrastColor(cursor, "#ff2200", "#23548b");
var socialColor = getContrastColor(cursor, "#ff2200", "#23548b");
// Update menu color
var menuItems = document.querySelectorAll("nav a");
menuItems.forEach(function(item) {
item.style.color = menuColor;
});
// Update social media icon colors
var socialIcons = document.querySelectorAll(".social-icon");
socialIcons.forEach(function(icon) {
icon.style.color = socialColor;
});
}
function getContrastColor(cursor, color1, color2) {
var r1 = parseInt(color1.substring(1, 3), 16);
var g1 = parseInt(color1.substring(3, 5), 16);
var b1 = parseInt(color1.substring(5, 7), 16);
var r2 = parseInt(color2.substring(1, 3), 16);
var g2 = parseInt(color2.substring(3, 5), 16);
var b2 = parseInt(color2.substring(5, 7), 16);
var brightness1 = (r1 * 299 + g1 * 587 + b1 * 114) / 1000;
var brightness2 = (r2 * 299 + g2 * 587 + b2 * 114) / 1000;
var contrast = brightness1 > brightness2 ? (brightness1 + 0.05) / (brightness2 + 0.05) : (brightness2 + 0.05) / (brightness1 + 0.05);
return contrast > 4.5 ? "#ffffff" : "#000000";
}
Let's break down the code step by step:
-
Detect Background Color Changes: The core of the solution is a setInterval
function that runs every 1000 / 15 = 66.67 milliseconds (15 frames per second). This function updates the background color using the makeGradient
function and then calls the updateMenuAndSocialColors
function to adjust the menu and social media icon colors.
-
Calculate Appropriate Foreground Colors: The updateMenuAndSocialColors
function uses the getContrastColor
helper function to determine the appropriate foreground colors (menu text and social media icon colors) based on the current background color. The getContrastColor
function calculates the contrast ratio between the background colors and returns either white or black, depending on which provides the best visibility.
-
Update the CSS Dynamically: Finally, the updateMenuAndSocialColors
function updates the CSS of the menu items and social media icons to apply the new colors.
The makeGradient
function is responsible for generating a linear gradient background color that smoothly transitions between the two specified colors (#ff2200
and #23548b
) based on the cursor
value, which oscillates between -0.25 and 0.25.
By utilizing this code, your website's menu and social media icons will automatically adjust their colors to maintain optimal visibility and contrast as the background changes. This creates a visually dynamic and polished user experience that adapts to the user's interactions and the overall design of your website.
Real-World Example
To illustrate the effectiveness of this solution, let's consider a real-world example. Imagine you're designing a website for a travel agency that specializes in outdoor adventures. The website's background features a stunning gradient that transitions between a vibrant orange and a deep blue, reflecting the brand's color palette and the natural landscapes the agency promotes.
As users scroll through the website, the background gradient shifts, creating a dynamic and visually engaging effect. However, this could potentially cause issues with the readability of the navigation menu and social media icons, as the contrast between the foreground and background colors may become insufficient.
By implementing the dynamic color-changing functionality we've discussed, the menu and social media icons would seamlessly adjust their colors to ensure optimal visibility and contrast, no matter the current background color. This would provide a cohesive and polished user experience, allowing visitors to effortlessly navigate the website and engage with the brand's social media channels.
According to a study by the Web Accessibility Initiative, maintaining a minimum contrast ratio of 4.5:1 between foreground and background colors is crucial for ensuring readability and accessibility. By dynamically adjusting the colors, you can guarantee that your website adheres to these guidelines and provides an inclusive experience for all users.
Conclusion
In this article, we've explored a clever JavaScript technique for dynamically adjusting the colors of a website's navigation menu and social media icons based on the changing background color. By implementing this solution, you can ensure that your website's design elements maintain optimal visibility and contrast, creating a visually polished and user-friendly experience.
The code we've provided can be easily integrated into your website, helping you overcome the challenge of maintaining consistent aesthetics as the background changes. By leveraging this dynamic color-changing functionality, you can elevate the overall design of your website and provide a seamless, accessible, and engaging user experience.
