left div width 100% increase when right div don't have content - javascript

I have 2 div both are 50% width and float left what I want if the right div doesn't have content then left div width should be 100%.
if ($('.wrap .box2').is(':empty')) {
$('.box2').hide();
$('.wrap .box1').css({
"width": "100%"
});
}
.wrap {
width: 100%;
}
.wrap .box1 {
width: 50%;
float: left;
background: red;
}
.wrap .box2 {
width: 50%;
float: left;
background: green;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="wrap">
<div class="box1">
<h1>Hello 1</h1>
</div>
<div class="box2">
<h1>Hello 2</h1>
</div>
</div>
So what I want if .box2 dont have text inside h1 then left div width should be 100%

if ($('.wrap .box2 h1').is(':empty')) {
$('.box2').hide();
$('.wrap .box1').css({
"width": "100%"
});
}
.wrap {
width: 100%;
}
.wrap .box1 {
width: 50%;
float: left;
background: red;
}
.wrap .box2 {
width: 50%;
float: left;
background: green;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="wrap">
<div class="box1">
<h1>Hello 1</h1>
</div>
<div class="box2">
<h1></h1>
</div>
</div>
I just ran this code and the left div took the whole space

Try this:
.wrap {
width: 100%;
display: flex;
}
.wrap .box1 {
width: 50%;
background: red;
flex-grow:1;
}
.wrap .box2 {
width: 50%;
background: green;
}
.wrap .box2:empty {
width: 0;
}
it works without using javascript/jquery and uses flex-boxes and the :empty selector.

How to show div again when scroll using vh?

I am trying to make a horizontal transition when scrolling down and up to show and resize (shrink) div of the first element. I used inline-block to put them in the same position so that when one has been shrunk the other element will slide through but I am a bit confused to achieve this.
I tried to calculate the height and the offset position of the first inline element. This obviously will work for the first inline element but it won't work on the second inline element because it's in the same offset position.
Can you guys give me a bit of direction or tips to achieve this?
var topofDiv = $(".one").offset().top;
var heightDiv = $(".one").outerHeight();
$(window).scroll(function() {
if ($(window).scrollTop() > (topofDiv + heightDiv)) {
$(".one").show();
} else {
$(".one").hide();
}
});
* {
margin: 0;
padding: 0;
}
body {
overflow-x: hidden;
}
.container {
width: 100vw;
height: 100vh;
}
.content-wrapper {
width: 100vw;
white-space: nowrap;
}
.section {
width: 100vw;
height: 100vh;
position: relative;
display: inline-block;
}
.section div {
font-size: 100px;

The show() and hide() calls need to be swapped over, they're in the wrong sides of your if condition. Also, the page height needs to be greater than the height of one of the .section elements for the transition to work properly, and the .container needs to be in fixed position for the scroll to have no effect on it. Try this:
var topofDiv = $(".one").offset().top;
var heightDiv = $(".one").outerHeight();
$(window).scroll(function() {
if ($(window).scrollTop() > (topofDiv + heightDiv)) {
$(".one").hide();
} else {
$(".one").show();
}
});

How to resize bottom fixed div when top div is collapsed?

I have two divs, one on top, the other on the bottom. I need to have the bottom div fixed, and to resize and occupy the space above when the div on top is collapsed. Links to the scenarios below. Is this possible to accomplish using only CSS? This is for an angularJS application.
UPDATE: Support for older versions of browsers, specifically IE, must also be considered.
Div1 expanded
Div1 collapsed
Yes, you can do this using flex. See snippet below.
$(document).ready(function() {
$("#div1").click(function() {
$(this).css("max-height", "50px")
});
});
body, html {
margin: 0;
height: 100%;
}
.container {
height: 100%;
display: flex;
flex-direction: column;
}
.box {
flex-grow: 1;
text-align: center;
}
#div1 {
background-color: #4472C4;
}
#div2 {
background-color: #ED7D31;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<!-- begin snippet: js hide: false console: true babel: false -->
Update
Since you noted in the comments you wanna support older browsers, the same as above can be achieved using the old fasion table layout.
$(document).ready(function() {
$("#div1").click(function() {
$(this).css("height", "50px")
});
});
html, body {
height: 100%;
margin: 0;
}
.container {
display: table;
height: 100%;
width: 100%;
}
.row {
display: table-row;
width: 100%;
}
.box {
display: table-cell;
color: #fff;
vertical-align: middle;
text-align: center;
}
#div1 {
background-color: #4472C4;
}
#div2 {
background-color: #ED7D31;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="row">
<div class="box" id="div1">
<strong>div1</strong>
</div>
</div>
<div class="row">
<div class="box" id="div2">
<strong>div1</strong>
</div>
</div>
</div>
You can try this.
html, body {
height: 100%;
margin: 0;
}
.wrapper {
display: table;
height: 100%;
width: 100%;
background: yellow;
}
.content {
display: table-row;
/* height is dynamic, and will expand... */
height: 100%;
/* ...as content is added (won't scroll) */
background: yellow;
}
.footer {
display: table-row;
background: grey;
}
<div class="wrapper">
<div class="content">
<h2>Content</h2>
</div>
<div class="footer">
<h3>Sticky footer</h3>
<p>Footer of variable height</p>
</div>
</div>
you can try this it works fine for me
<div class="wrapper">
<div class="container">
<div class="top-div">
topd div
</div>
<div class="bottom-div">
bottom div
</div>
</div>
</div>
CSS
.wrapper{
float:left;
height:100%;
}
.container {
position:absolute;
display: block;
float: left;
width: 100%;
height: 100%;
min-height:100%;
}
.top-div {
margin: 5px;
float: left;
position: fixed;
top: 0;
width: 90%;
height: 30%;
background-color: red;
}
.bottom-div {
margin: 5px;
position: absolute;
float: left;
bottom: 0;
width: 90%;
background-color: green;
}
use jQuery
$(function() {
var containerH = $(".container").height();
var topdivH = $(".top-div").height();
$(".bottom-div").height(containerH - topdivH);
});

smoothscroll to target on certain div

I am trying to find element with smoothscroll effect when I click button, How I can scroll into target if target is inside div.
I'm trying this way, but didnt work. Is it possible scroll to target if its inside div
$(document).ready(function(){
$('button').click(function(){
$('.box').animate({
scrollTop: $("#find").offset().top
}, 2000);
});
});
.box{
clear: both;
}
.left{
float: left;
width: 20%;
height: 200px;
overflow-x: hidden;
background-color: red;
}
#find{
margin-top: 400px;
}
#find p{
background-color: green
}
.right{
float: left;
margin-left: 10px;
width: 50%;
background-color: yellow;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="box">
<div class="left">
<div id="find">
<p>find me</p>
</div>
</div>
<div class="right">
<button>jump</button>
</div>
</div>
Your logic is correct, you're just scrolling the wrong element. You need to call animate() on the .left element as that is the one which is overflowed:
$(document).ready(function() {
$('button').click(function() {
$('.left').animate({
scrollTop: $("#find").offset().top
}, 2000);
});
});
.box {
clear: both;
}
.left {
float: left;
width: 20%;
height: 200px;
overflow-x: hidden;
background-color: red;
}
#find {
margin-top: 400px;
}
#find p {
background-color: green
}
.right {
float: left;
margin-left: 10px;
width: 50%;
background-color: yellow;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="box">
<div class="left">
<div id="find">
<p>find me</p>
</div>
</div>
<div class="right">
<button>jump</button>
</div>
</div>
You need to add scrollTop on .left, as scrollbar appears there instead of .box i.e. overflow-y is visible and scroll-able on .left and not on .box.
$(document).ready(function(){
$('button').click(function(){
var bt = $("#find").offset().top;
$('.left').animate({
scrollTop: bt
}, 2000);
});
});
.box{
clear: both;
}
.left{
float: left;
width: 20%;
height: 200px;
overflow-x: hidden;
background-color: red;
}
#find{
margin-top: 400px;
}
#find p{
background-color: green
}
.right{
float: left;
margin-left: 10px;
width: 50%;
background-color: yellow;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="box">
<div class="left">
<div id="find">
<p>find me</p>
</div>
</div>
<div class="right">
<button>jump</button>
</div>
</div>

I need help to make .second div to .slideToggle from bottom border of .first div.
The problem:
Because of the bottom:0 in that way, the the height of the .second div start from the bottom.
The solution:
Try to wrap the .second with wrapper. So the slide animation will start from the top.
Like this:
jQuery(document).ready(function () {
$("button.filters").click(function(){
$("div.second").slideToggle("slow");
});
});
.main {
position: relative;
display:block;
height: 320px;
color: #fff;
background-color: grey;
}
.first {
position: absolute;
bottom: 15%;
height: 70px;
background-color: white;
}
.second-wrapper {
position: absolute;
bottom: 0%;
height: 30px;
}
.second {
display:none;
background-color: green;
}
.second p {
margin:0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="main">
<div class="first">
<p>some content</p>
<button class="filters">filters</button>

How to increase size of something in class, but not other elements in class?

Let's say I have four images inside a div. they all have a width of 5.5%
[_o__o__o__o_]
I want to use javascript to change the target that is moused over (hovered on), and have it look like this:
[_o__O__o__o_]
so I made the width of the target increase
however it also pushes the other elements to the side instead of staying where they are so it's more like:
[_o___O___o__o_]
I don't know how to make the other elements stay exactly where they are instead of being pushed.
The issue is that YES I am successfully able to alter the width.
BUT changing the width of one element pushes the surrounding elements to the respective right and left.

You can use flexbox for this one:
.wrapper {
display: flex;
display: -webkit-flex;
display: -moz-flex;
width: 400px;
background-color: red;
}
.item {
position: relative;
width: 25%;
height: 200px;
}
.circle {
position: absolute;
bottom: 20px;
left: 50%;
-webkit-transform: translate(-50%, -50%);
background: white;
width: 20px;
height: 20px;
border-radius: 50%;
transition: all .3s;
}
.item1 { background-color: blue; }
.item2 { background-color: red; }
.item3 { background-color: orange; }
.item4 { background-color: yellow; }
.item:hover .circle{
background-color: black;
height: 40px;
width: 40px;
}
<div class="wrapper">
<div class="item item1">
<div class="circle"></div>
</div>
<div class="item item2">
<div class="circle"></div>
</div>
<div class="item item3">
<div class="circle"></div>
</div>
<div class="item item4">
<div class="circle"></div>
</div>
</div>
As I was explaining, you need to set a higher z-index to "be above" the non-hovered boxes. And set negative left-right margins, equivalent to the additional width from hovering to prevent everything from moving around.
Below is a working example, with percentages.
body {
width: 300px;
height: 100px;
}
.myClass {
width: 20%;
height: 50%;
position: relative;
z-index: 1;
float: left;
}
.myClass:hover {
width: 30%;
height: 70%;
z-index: 10;
margin: 0 -5%;
}
body .myClass:nth-child(1) {
background-color: red;
}
body .myClass:nth-child(2) {
background-color: green;
}
body .myClass:nth-child(3) {
background-color: blue;
}
body .myClass:nth-child(4) {
background-color: yellow;
}
