Could anyone offer some advice on how to temporarily hide the header of my website for about 4.5 seconds while a popup animation is running? The issue is that the header loads before the animation, causing it to look unprofessional. The URL of my website is viatgesestudiants.com. Thank you in advance!
If you are looking to make your header stand out, give this CSS snippet a shot:
.header-section, .navbar {
animation: enlarge 2s;
}
@keyframes enlarge
{
0%{transform:scale(0);}
100%{transform:scale(1);}
}
To implement CSS classes effectively, follow these steps:
transition property for the attributes within your hidden class.setTimeout() function.You can also utilize custom attributes to determine when the "hidden-class" should be removed after a certain delay!
Ensure to establish a default value in case the attribute is not provided.
This technique allows you to display multiple elements at varying intervals, all configured in the HTML code.
for (let el of document.querySelectorAll('.onload-hidden')) {
setTimeout(() => el.classList.remove('onload-hidden'),
el.getAttribute('data-delay') || 1000); // Specified delay or fallback delay
}.onload-hidden {
visibility: hidden;
opacity: 0;
}
div {
transition: 1s;
}<div>
<h1>Always displayed</h1>
<p>This <div> will always remain visible.</p>
</div>
<div class="onload-hidden" data-delay="4000">
<h1>Initially concealed - 1</h1>
<p>This <div> will appear after a specific delay!</p>
</div>
<div class="onload-hidden" data-delay="500">
<h1>Initially obscured - 2</h1>
<p>This <div> will become visible after a set delay!</p>
</div>A different approach to accomplish the task:
//JS
// This function will execute after 4.5 seconds and change the CSS class
setTimeout(() => {
document.querySelector('#header').className = "headerShow headerHide"
},4500)/* CSS */
body {
background: black;
}
.headerHide {
display: none
}
.headerShow {
display: block;
background: red;
position: absolute;
width: 100vw;
text-align: center;
font-size: 30px;
top: 0
} /* HTML */
