Hello everyone, I am currently working on coding a website logo that decreases in size as the user scrolls down, similar to the effect seen on this website: . I am relatively new to HTML and was wondering if there are any specific commands or techniques that can be used to achieve this resizing effect based on scrolling.
Any help or suggestions would be greatly appreciated. Thank you!
I have personally implemented a similar feature before and found it to be surprisingly easy
To start, you can include CSS code like the following for smooth animated transitions without relying on jQuery:
.logo {
height: 100px;
-webkit-transition: height .4s ease,opacity .3s ease,background-color .3s ease;
-o-transition: height .4s ease,opacity .3s ease,background-color .3s ease;
transition: height .4s ease,opacity .3s ease,background-color .3s ease
}
Next, utilize JavaScript to add a class to the image after a certain amount of scrolling:
$( document ).ready(function() {
"use strict"; // Utilizing strict mode
var scrollInit = $(window).scrollTop();
var windowWInitial = $(window).width();
if (scrollInit >= 2) {// Adjust this value based on your scrolling needs
$("#header").addClass("sticky-header");
}else{
$("#header").removeClass("sticky-header");
}
}
Simply adjust the height by setting another CSS variable for the sticky-header class:
.logo .sticky-header {
height: 60px;
}
By implementing this, the image will adjust its height when reaching your specified scroll length.
It's recommended to use Chrome Devtools to inspect elements and learn from others' implementations. Feel free to explore my website TechGorilla for a real-life example.
Note: I used jQuery in this solution, which can save time and is commonly used on websites not utilizing frameworks like React or Angular
In my opinion, there is no need for javascript in this scenario. By utilizing only html and css, you can effectively build your company's website using html canvas. Incorporate a meta tag for viewport to ensure your images adjust based on screen size. Additionally, consider adding max-width: 100% for the logo to prevent it from becoming too large.
