Div doesn't show by just changing name? - html

I'm practicing with web development and I have a very weird problem with HTML and CSS.
html {
height: 100%;
}
* {
margin: 0 auto;
}
body {
background-repeat: no-repeat;
background-image: linear-gradient(to bottom, #71c7d1, #417e8a);
height: 100%;
position: relative;
}
#banner {
right: 20%;
position: absolute;
text-align: center;
height: 50px;
width: 60%;
background-color: #3231ff;
}
#friendRequests {
position: absolute;
float: left;
height: 100%;
width: 20%;
background-color: #3231ff;
}
#friendsList {
position: absolute;
float: left;
height: 20%;
width: 20%;
background-color: #3231ff;
}
<!DOCTYPE html>
<html>
<head>
<title>Welcome</title>
<link rel="stylesheet" href="chatscreen.css">
</head>
<body>
<div id="banner"><h1>Welcome to your TicTac</h1></div>
<!--<div id="friendRequests"></div>-->
<div id="friendRequests"></div>
<div id="chatScreen"></div>
</body>
</html>
As you can see, #friendsList and #friendRequests are exactly the same. Note the line after the div that has been commented out, it has the id friendRequests. When I load the page, the div doesn't show up. But here is where I get confused. If I change the id of that div to friendsList, it does show up, but those two identities have exactly the same properties (I did this just to debug, friendRequests will have other properties). I even commented the friendsList out in CSS and I even removed it, it still doesn't change. Can someone explain to me why this apparently only depends on the name of the id? Thanks!
Big Update:
Apparently the script works perfectly fine in Microsoft Edge, so the problem lies in Chrome. Using Element Inspector, I discovered that the #friendRequests is actually never loaded in Chrome!! What might be the issue here?

Both divs #friendsList and #friendRequest are set with position: absolute; and float: left;.
This means both will be aligned to the left side of the screen regardless of other elements. As a consequence, both divs are on top of each other and only one is visible (specifically the one which is defined later in html).
You should remove the position: absolute from the divs. Or make them relative, so they are aligned next to each other, depending on the order in the html.
html {
height: 100%;
}
* {
margin: 0 auto;
}
body {
background-repeat: no-repeat;
background-image: linear-gradient(to bottom, #71c7d1, #417e8a);
height: 100%;
position: relative;
}
#banner {
right: 20%;
text-align: center;
height: 50px;
width: 60%;
background-color: blue;
position: relative;
}
#friendRequests {
float: left;
height: 100%;
width: 20%;
background-color: red;
position: relative;
}
#friendsList {
float: left;
height: 20%;
width: 20%;
background-color: yellow;
}
<!DOCTYPE html>
<html>
<head>
<title>Welcome</title>
<link rel="stylesheet" href="chatscreen.css">
</head>
<body>
<div id="banner"><h1>Welcome to your TicTac</h1></div>
<div id="friendRequests"></div>
<div id="friendsList"></div>
<div id="chatScreen"></div>
</body>
</html>

The reason for this is both the div are having same css when you use the same id because of which the divs are overlapping on each other.
The id should be unique.
To understand the difference, I have shifted "friendRequests 2" block a bit left.
html {
height: 100%;
}
* {
margin: 0 auto;
}
body {
background-repeat: no-repeat;
background-image: linear-gradient(to bottom, #71c7d1, #417e8a);
height: 100%;
position: relative;
}
#banner {
right: 20%;
position: absolute;
text-align: center;
height: 50px;
width: 60%;
background-color: #3231ff;
}
#friendRequests {
position: absolute;
float: left;
height: 100%;
width: 20%;
background-color: #3231ff;
}
#friendsList {
position: absolute;
float: left;
height: 20%;
width: 20%;
background-color: #3231ff;
}
.left_block{
left: 21%;
}
<!DOCTYPE html>
<html>
<head>
<title>Welcome</title>
<link rel="stylesheet" href="chatscreen.css">
</head>
<body>
<div id="banner"><h1>Welcome to your TicTac</h1></div>
<div id="friendRequests">friendRequests 1</div>
<div id="friendRequests" class="left_block">friendRequests 2</div>
<div id="chatScreen"></div>
</body>
</html>

Thank you for answering, I found the solution. The problem wasn't the script, it was my browser apparently. Like I commented a few times, loading the page in Edge worked perfectly fine. I discovered using the debugger tool that the CSS file wasn't loaded completely for one or another reason. Thus I suspect this might be a bug in Chrome.

my fixed header does not overlap the other element

when I scroll down on my page, my container overlap the header, but I want my header to overlap the container, so I made my header on a fixed position, but it does not work
here is my html code:
<html>
<head>
<meta charset="UTF-8" />
<script src="script.js"></script>
<link rel="stylesheet" type="text/css" href="styles.css" />
</head>
<body>
<div class="page">
<header class="leheader">
<div id="bloc1"></div>
<img src="https://i.imgur.com/dm6H7GV.png">
<div id="bloc2"></div>
</header>
<main class="container"></main>
</div>
</body>
</html>
and here is my css code:
body,
html,
.page {
background: #666666;
width: 99%;
height: 100%;
}
.leheader {
display: flex;
width: 99%;
position: fixed;
flex: 1 100%;
height: calc(100%-50px);
}
#bloc1 {
margin-left: 1px;
margin-top: 0.5px;
height: 50px;
width: 90px;
background: #cccccc;
border-radius: 10px 0 0 0;
}
#bloc2 {
background: #467491;
margin-top: 4px;
width: 93%;
height: 37px;
}
.container {
position: absolute;
top: 57px;
left: 9px;
background: #cccccc;
width: 99%;
height: calc(100% - 33px);
}
where is the problem ?
Try adding the z-index property to the header.
like this....
z-index: 2
In CSS to make something Fixed position you also need to give it a z-index (which is its position on z-axis). Read more about Z-Index here. Apart from it you also have to give it a position in terms of top, left, bottom and left to tell it where it has to fixed.
.leheader {
display: flex;
width: 99%;
position: fixed;
top:0;
left:0;
z-index:2;
flex: 1 100%;
height: calc(100%-50px);
}

My floating element disturbs other elements

I have a problem with my brand new html & css sites : I want to have a that opens when hovering on a floating element of itself. The problem is not on animation but on layout. When it's empty, it works well, but when I add content into the , it goes under the floating element. To solve this, I've tried different overflow values as explained here, but of course the part of the whitch is "outside" of it got impacted.
(in this sample, the "menu" is already opened)
section
{
background-color: white;
margin: 10px;
}
.scroll_aside{
overflow-y: auto;
width: 100%;
height: 100%;
}
.aside_left{
width: 70%;
height: 100%;
display: block;
background-color: gold;
position: fixed;
top:0;
}
.aside_left .cote{
position: relative;
top:0px;
right: -80px;
width: 80px;
background-color: orange;
margin-top: 100px;
margin-left:0;
float: right;
}
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<link rel="stylesheet" href="TEST2.css"/>
</head>
<body>
<div class='aside_left'><span class='cote' onclick="openjourney()">Floating on the right</span>
<div class="scroll_aside">
<section style='height: 400px'>Section 1</section>
<section style='height: 800px'>Section 2</section>
</div>
</div>
</body>
</html>
Another thing I've noticed is that when the content is thin enough, it goes to the top....
But what I want, is to have the content taking all the , so going at the top and with width=100%.
Is there a way to do that ?
Thank you in advance....
Instead of float use absolute position:
section {
background-color: white;
margin: 10px;
}
.scroll_aside {
overflow-y: auto;
width: 100%;
height: 100%;
}
.aside_left {
width: 70%;
height: 100%;
display: block;
background-color: gold;
position: fixed;
top: 0;
}
.aside_left .cote {
position: absolute;
left: 100%;
width: 80px;
background-color: orange;
top: 100px;
}
<div class='aside_left'><span class='cote' onclick="openjourney()">Floating on the right</span>
<div class="scroll_aside">
<section style='height: 400px'>Section 1</section>
<section style='height: 800px'>Section 2</section>
</div>
</div>

Fixed navbar covered by rest of the page when scrolling down

I would like to have an element looking like a navbar at the top of my website:
It should be fixed, like a navbar. However, as soon as the user scrolls down, it should disappear under the rest of the content:
I tried something like that, where the #title element is the "navbar":
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<div id="title" class="center-align">
<h1>Title</h1>
<h2>Subtitle</h2>
</div>
<div id="showcase" class="center-align">
</div>
</body>
<style>
#title {
position: fixed;
width: 100%;
height: 50vh;
z-index: -1;
}
#showcase {
margin-top: 50vh;
height: 75vh;
background-color: #212121;
}
</style>
</html>
However this is not working, the #title seems to be also affected by the 50vh margin-top (you can see it by setting its z-index to 1 instead of -1).
No need to use z-index
By default sibling are stacking by the order from bottom to top so the 1st child will at the bottom, the last child at the top. See example here:
Example of sibling z-index:
.div1 {
width: 100px;
height: 100px;
background: red;
}
.div2 {
margin-top: -50px;
margin-left: 50px;
width: 100px;
height: 100px;
background: green;
}
.div3 {
margin-top: -50px;
margin-left: 100px;
width: 100px;
height: 100px;
background: aqua;
}
<div class="div1">
div1
</div>
<div class="div2">
div2
</div>
<div class="div3">
div3
</div>
Solution to your problem:
#title {
width: 100%;
height: 100px;
text-align: center;
position: fixed;
top: 0;
}
#showcase {
margin-top: 120px;
height: 90vh;
background: black;
}
<div id="title">
<h1>Title</h1>
<h2>Subtitle</h2>
</div>
<div id="showcase">
</div>
Try change your style with the following css . I made some changes for test purpose.
#title {
position: fixed;
width: 100%;
height: 50vh;
z-index: -1;
background: red ;
top:0;
}
#showcase {
margin-top: 50vh;
height: 275vh;
background-color: #212121;
}
Hope it helps
Here's an example using a fixed navabr and a normal div for the content having a margin-top:
body {
margin:0;
height:100%;
}
.navbar {
width: 100%;
height: 50px;
line-height: 50px;
position: fixed;
background-color: lightblue;
z-index:-1;
}
.content {
width: 100%;
float: left;
height: 1000px;
margin-top: 50px;
background-color: red;
}
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<div class="navbar">
Navbar
</div>
<div class="content">
Content
</div>
</body>
</html>
Add top: 0 to the title id. Like:
#title {
position: fixed;
width: 100%;
height: 50vh;
z-index: 1;
top: 0;
}

html and css placing a non-fixed div between two fixed divs

I'm trying to build a website with 4 main divs (more to come later), 3 of which are fixed, so they dont move when i scroll, and one of them is not fixed. i've been going at it for around 6 hours and 30 minutes straight, googled for possible answers, checked youtube and spent atleast 2 hours looking at stackoverflow posts, none of which really pointed me in the right direction.
design im looking to get:

left: ;
}
.paragraph {
background-color: red;
width: 100%;
height: 50vh;
}
i tried changing the width of the .main div, but regardless of what i try the div either goes under the .contact or .menu div
the .paragraph divs go into to the .main div, to hold some text and images once the .main div is properly positioned. the sizes of the divs in my source arent completely like they are in my design yet cus i kept trying thing to maybe solve my problem.
the .js file is currently still empty so i didnt post any source of it.
Any help is welcome: links; sources; comments; if you know something that might point me into the right direction, please post it!
edit: i tried using a wrapper, but that didnt work out too wel for me, i probably did something wrong, i posted the source that looks the most like my design when i open in in browser.

I ignored your existing code and made a new, HTML5 and responsive way of creating such a layout. I hope this helps you in understanding this concept better
http://jsfiddle.net/7k9vhk4r/2/
The key is using fixed and relative positioning, together with creating offsets based on percentages.
I just changed this:
added margin:0 to body
Change .main rules to :
/*width: 100%;*/
margin: 200px 200px 0;
height: 2000px; /* to make it big */
/*left: ;*/

Horizontal Scrolling With two divs

What i want to do is to scroll my web page in two direction that is leftPanel in left to right direction while rightPanel in right to left direction but the header remain fixed in its postion. But i am stuck some where.
here is my code:
HTML File-
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>My Page </title>
<link rel='stylesheet' href='css/default.css'>
</head>
<body class='aboutUsBody'>
<div id='header'></div>
<div id='mainPanel'>
<div id='leftPanel'></div>
<div id='rightPanel'></div>
</div>
</body>
</html>
CSS File-
html{
width: 100%;
height: 100%;
}
body{
width: 100%;
height: 100%;
margin: 0px;
}
#header{
width: 100%;
height: 10%;
background: #bad960;
}
#mainPanel{
height: 90%;
display: inline;
overflow-y: scroll;
}
#leftPanel{
float: left;
margin-left: -200px;
display: inline;
position: relative;
width:100 %;
height: 100%;
background: red;
}
#rightPanel{
display: inline-block;
position: relative;
width:100%;
height: 100%;
background: black;
}
please look at the image for further explaination:
at the page load scroll will be at center and the two divs positioned accordingly, when i scroll up the leftPanel scrolls from left to right and when i scroll down its rightPanel move from right to left.
What should i do ??
What you are doing is quite awkward to achieve because the scrollable divs must have a known width otherwise it is really difficult to control the line-wrap to act in your favour, but if you have a fairly static design to aim for it can work quite well.
You have quite a few strange things in your code that don't seem to be doing anything useful but it could be due to me misunderstanding what you are aiming for, also, some javascript might be essential for this, at least to get the left panel to start scrolled all the way to the right.
Here is my working css for something like what you are trying to do:
html{
width: 100%;
height: 100%;
}
body{
width: 100%;
height: 100%;
margin: 0px;
}
#header{
width: 100%;
height: 10%;
background: #bad960;
}
#mainPanel{
height: 90%;
}
#leftPanel{
float: left;
width:50%;
height: 100%;
background: red;
overflow-x: auto;
}
#rightPanel{
float: left;
color: red;
width:50%;
height: 100%;
background: black;
overflow-x: auto;
}
.horizScroll{
width: 800px;
}
#leftPanel .horizScroll{
direction: rtl;
}
And a jsfiddle
I have done some research and i had achieved it by adding a little jquery.
My code is :
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>My Page </title>
<link rel='stylesheet' href='css/default.css'>
<script src="./jQuery.1.10.0.js"></script>
<script>
$(document).ready(function(){
$("#mainPanel").scrollLeft(document.body.clientWidth*0.25);
$(window).bind('mousewheel DOMMouseScroll', function(event){
if (event.originalEvent.wheelDelta > 0 || event.originalEvent.detail < 0) {
}
else {
}
});
});
</script>
</head>
<body class='aboutUsBody'>
<div id='header'></div>
<div id='mainPanel'>
<div id='panelOne' class='panel'></div>
<div id='panelTwo' class='panel'></div>
</div>
</body>
</html>
CSS file
html{
width: 100%;
height: 100%;
}
body{
width: 100%;
height: 100%;
margin: 0px;
}
#header{
width: 100%;
height: 10%;
background: #bad960;
position: fixed;
}
#mainPanel{
top:10%;
position: relative;
width:100%;
height: 90%;
overflow-x:scroll;
display: block;
background: yellow;
}
#panelOne{
position: absolute;
display: inline;
width: 1000px;
height: 100%;
background: red;
}
#panelTwo{
position: absolute;
display: inline;
margin-left: 1000px;
width: 1000px;
height: 100%;
background: aqua;
}
