I am writing a dropdown component in svelte with tailwind css and i cannot get the dropdown menu to be under the button/anchored to it meaning it always appears under it.
I have tried using relative and other positional tailwind properties but i haven't had any succes.
I am also new to tailwind and mainly have backend experience so this is a bit hard for me if anyone can help or point me towards an example then please do so!
Dropdown example in Svelte
https://svelte.dev/repl/05d770c4baa748b2b0973afec4d59051?version=3.55.1
<script>
// Button binding
let button;
// State
let open = false;
let top = 0, left = 0;
// React to opening
$: if (open) {
setDropdownPosition();
}
function setDropdownPosition() {
const rect = button.getBoundingClientRect();
top = rect.bottom;
left = rect.left;
}
</script>
<button bind:this={button} on:click={() => open = !open}>{!open ? 'Open' : 'Close'} Dropdown!</button>
{#if open}
<ul class="dropdown" style:top={top} style:left={left}>

i made a loading bar for my website. On the live preview with brackets, when I scroll down to my bar, the animation become visible. When I open my html page with a browser (chrome or edge), The loading bar animation does not appear... Although I think I used the right prefixes. Below you can see my code:
**CSS**
.laden100 {
animation-name: laden100;
-webkit-animation-name: laden100;
animation-duration: 4s;
-webkit-animation-duration: 4s;
visibility: visible;
width: 100%;
height: 20px;
background-image: linear-gradient(to bottom, #308355, #308355, #308355, #00cc66);
background-image: -webkit-linear-gradient(to bottom, #308355, #308355, #308355, #00cc66);
box-shadow: 5px 5px 5px grey;
border-radius: 5px 5px 5px 5px;
position: relative;
margin-top: 20px;
margin-left: 20px;
margin-right: 20px;
}
#keyframes laden100 {
0% {
opacity: 0;
width: 0%;
}
100% {
opacity: 1;
width: 100%;
}
}
#-webkit-keyframes laden100 {
0% {
opacity: 0;
width: 0%;
}
100% {
opacity: 1;
width: 50%;
}
}
**HTML**
<div class="container wit mt-5">

**JAVASCRIPT**
<!----------------------- only load the load bar on scroll-------------->
<script>
$(document).ready(function() {
// Add smooth scrolling to all links in navbar + footer link
$(".navbar a, footer a[href='#myPage']").on('click', function(event) {
// Make sure this.hash has a value before overriding default behavior
if (this.hash !== "") {
// Prevent default anchor click behavior
event.preventDefault();
// Store hash
var hash = this.hash;
// Using jQuery's animate() method to add smooth page scroll
// The optional number (900) specifies the number of milliseconds it takes to scroll to the specified area
$('html, body').animate({
scrollTop: $(hash).offset().top
}, 900, function() {
// Add hash (#) to URL when done scrolling (default click behavior)
window.location.hash = hash;
});
} // End if
});
$(window).scroll(function() {
$(".laadbalk100").each(function() {
var pos = $(this).offset().top;
var winTop = $(window).scrollTop();
if (pos < winTop + 600) {
$(this).addClass("laden100");
}
});
});
})
</script>
I used prefixes because I think it has something to do with browser support. According to me, Brackets uses plugins to add the right prefixes.
OK sry Guys,
I found the answer to my own question... :D.
Because browsers have different screen resolutions, I had to increase wintop +600 to wintop +1000. See the correction below:
$(window).scroll(function() {
$(".laadbalk100").each(function() {
var pos = $(this).offset().top;
var winTop = $(window).scrollTop();
if (pos < winTop + 1000) {
$(this).addClass("laden100");
}
});
});
My vue app is shared between web page and electron app on touch device. On this touch device I want to include extra style. So in my App.vue there is:
<script>
var is_electron = process.hasOwnProperty("versions") && process.versions.hasOwnProperty("electron")
var is_embedded = is_electron && require("electron").remote.process.argv.includes("-e")
</script>
<style>
* {
transition-property: none !important;
transform: none !important;
animation: none !important;
cursor: none !important;
}
</style>
How can I conditionally include this * style ?
If the platform-specific styling is minimal, I would suggest to use some helper classes. You can even style subcomponents by scoping the css within one of these selectors.
<template>
<main :class="classes">
<!-- Hello world -->
</main>
</template>
<script>
var isElectron = process.hasOwnProperty("versions") && process.versions.hasOwnProperty("electron")
var isEmbedded = isElectron && require("electron").remote.process.argv.includes("-e")
export defualt {
name: 'App',
computed: {
classes () {
return {
electron: isElectron,
embedded: isEmbedded
}
}
}
}
</script>
<style>
.electron:not(.embedded) * {
border: 1px solid blue;
}
.embedded:not(.electron) * {
/* What kind of sorcery is this? */
}
.electron.embedded * {
border: 1px dotted red;
}
main:not(.electron):not(.embedded) * {
border: 1px dashed green;
}
</style>
I'm hoping to combine the following two codes to create a map that not only searches with a layer of KMZ on top, but also shows navigation options in the infowindow. An example of the two maps side by side can be viewed here. But I want to combine the two maps into one. I've included my attempt at this at the bottom of this post - but it doesn't work.
Firstly, I've adapted this code for searching a map with my kmz (or kml) layered onto it and it works just fine ...

This second code works great with adding a direction link to the info window so you can drive there using your smartphone ...

remove the final } in the javascript, it generates a syntax error: Uncaught SyntaxError: Unexpected token }.
change suppressInfoWindows: false to suppressInfoWindows: true (removes the extraneous second copy of the infowindow).

I've been searching for a way to do this effect: http://www.discovershadow.com/
Especially the iPhone reveal part at the bottom where the iPhone stays but the content inside changes at the same time as the background.
Can this be achieved with only css or is it something much more complicated?
This is the way that I found to do this... no one seemed interested in the question but I hope you like the answer:
<html>
<head>
<style>
html, body {
min-height: 100%;
margin: 0;
padding: 0;
}
#container {
height: 100%;
width: 100%;
overflow-y: scroll;
position: fixed;
}
.items {
width: 100%;
height: 102%;
background-attachment: fixed;
background-position: 50%;
background-repeat: no-repeat;
position: relative;
}
#box1 {
background-image: url(yourimage1.png);
background-color: #03F;
}
#box2 {
background-image: url(yourimage2.png);
background-color: #609;
}
#box3 {
background-image: url(yourimage3.png);
background-color: #3C0;
}
</style>
</head>
<body>
<div id="container">
<div class="items" id="box1"></div>
<div class="items" id="box2"></div>
<div class="items" id="box3"></div>
</div>
</body>
</html>
Yes can achieve that... You have not added any code or not even tried i think. Here is simple code for you to get you started.
.a
{
background-image : url('http://hdwallpaper2013.com/wp-content/uploads/2013/02/Beautiful-Nature-Images-HD-Wallpaper.jpg');
height: 200px;
width: 100%;
position: fixed;
}
p
{
color : #000;
font-size: 72px;
position: relative;
z-index: 999;
}

This effect does require CSS + Javascript, there is no way to do it effectively without using these technologies. You could have the iPhone centred on screen and the rest of the screen move around it but it wouldn't create such as nice effect as seen on the website.
I would personally recommend looking at the source of the target website and investigate yourself how it was achieved, never hurts to have a sneek peek at source from other websites.
Looking at that sites script.js page they handle scrolling with
// handle scrolling
$window.scroll(function() {
handleScroll();
});
Which does this. You will need to look at the full code to work out exactly how its done.
// handle scroll
function handleScroll() {
scrolledWin = getPageScroll();
$body.addClass('scrolling');
// show logo
if((scrolledWin * 1.5) > winH) {
$body.addClass('content');
}
// show navigation
if(scrolledWin > 50) {
$body.addClass('scrolled');
}
// app img animation
if(topOff >= scrolledWin) {
$appImg.removeClass('sticky');
} else {
$appImg.addClass('sticky');
}
if(topOff2 >= scrolledWin) {
$appImg2.removeClass('sticky');
} else {
$appImg2.addClass('sticky');
}
// fix navigation issue on top scroll
if ((scrolledWin > -(winH - (winH * (f1 *0.8)))) && $('#hook2').hasClass('inViewport')) {
$nav.attr("class", "").addClass('a2');
} else if ($('#hook2').hasClass('inViewport')) {
$nav.attr("class", "").addClass('a1');
}
//fix navigation issue between how it works and next section
if ($s9.hasClass('inViewport')) {
if ($('#hook5').hasClass('inViewport')) {
$nav.attr("class", "").addClass('a5');
} else {
$nav.attr("class", "").addClass('a4');
}
}
//fix navigation issue between Experts and next section
if ($sExperts.hasClass('inViewport')) {
if ($('#hook6').hasClass('inViewport')) {
$nav.attr("class", "").addClass('a6');
} else {
$nav.attr("class", "").addClass('a5');
}
