Exploring the world of creating a "sticky" navigation bar and menu using only the properties of "position" and "float", alongside JavaScript, has been on my agenda lately. This exercise serves as a great way to enhance my JavaScript skills.
Everything seems to be functioning smoothly, except for a minor bug when resizing the page causing positions to become non-static. To replicate this issue, one must first "run the code snippet" then click on "full page". Proceed to scroll down until both the "menu" and "sidebar" positions become "fixed". Now, upon resizing the page, you'll notice an automatic scroll downward.
(function(){
function makeSticky(element){
var rect = element.getBoundingClientRect();
var top = rect.top + scrollY;
var fakeElement = document.createElement('div');
fakeElement.style.width = rect.width + "px";
fakeElement.style.height = rect.height + "px";
var offset = parseInt(element.getAttribute('data-offset') || 0, 10);
var hasDataConstraint = element.getAttribute('data-constraint');
if(hasDataConstraint != null) {var constraint = document.querySelector(hasDataConstraint);}
else {var constraint = document.body;}
var constraintRect = constraint.getBoundingClientRect();
var constraintBottom = constraintRect.top + scrollY + constraintRect.height - offset - rect.height;
function onResize(){
element.style.width = "auto";
element.style.position = 'static';
fakeElement.style.display = "none";
rect = element.getBoundingClientRect();
top = rect.top + scrollY;
fakeElement.style.width = rect.width + "px";
fakeElement.style.height = rect.height + "px";
fakeElement.style.display = "block";
constraintRect = constraint.getBoundingClientRect();
constraintBottom = constraintRect.top + scrollY + constraintRect.height - offset - rect.height;
onScroll();
}
... (remaining code unchanged)
