I don't know how to explain this, but maybe in this case picture tells story instead of me:
Shortly if you cannot see it. I'm trying to place logo inside multiple areas (header, body, content) like a global image.
Is that possible with CSS, JavaScript, HTML, PHP?
And if it is, any guides or tips?
You can place your logo inside of the nav (in this case) section. The logo must be absolutely positioned, so that it doesn't mess up with other element's alignment, and your nav section must be relatively positioned, so the logo gets placed in relation to the nav container (even if it's absolute!).
You didn't provide any HTML/dimensions, so we're pretty much left to guess, but here's how it would look, picking arbitrary dimensions.
.nav {
position: relative;
height: 100px;
}
/* .logo is a child of .nav */
.logo {
position: absolute;
top: -50px;
height: 200px;
width: 200px;
left: 0;
}
Take a look:
body {
color: #fff;
text-align: center;
}
.header {
height: 100px;
background: red;
}
.nav {
position: relative;
height: 70px;
background: blue;
}
.logo {
position: absolute;
width: 200px;
height: 200px;
left: 0;
top: -50px;
}
.body {
height: 250px;
background: purple;
}
.footer {
height: 100px;
background: lightblue;
}
<div class="header"> Header </div>
<div class="nav">
<img src="http://www.udavinci.com/wp-content/uploads/2014/09/stackoverflow.png" class="logo"/>
Nav
</div>
<div class="body"> Body </div>
<div class="footer"> My Feet </div>
Alternatively, you may also place your logo outside of everything but inside of the body tag, and just use position: absolute, and tweak it's position (top, left, etc..), according to the dimensions of the relevant elements.
You can put your logo in header and position with :
.your-logo-class {
position: relative;
top: 100px; // Adjust this value
}
You could do it like this:
body { margin: 0; padding: 0; background-color: black;}
#top { background-color: red; width: 100%; height: 100px; }
#nav { background-color: blue; width: 100%; height: 50px; }
#content { background-color: green; width: 400px; height: 500px; margin: 0 auto;}
#footer { background-color: purple; width: 100%; height: 50px; }
<body>
<div id="top">
</div>
<div id="nav">
<img src="images/logo.png" style="padding: 10px;">
</div>
<div id="content">
</div>
<div id="footer">
</div>
</body>
Or you could add position: absolute; to the img style="" and then play around with the margin/padding.
Hmm, a logo is basically an <img> tag, you can place them where ever you like, just give all those <img> tags a class and style it the way you want.

There are two containers. One of which is the main (essentially, the parent) container. Another is a child container that serves as a tag for categorizing the content. The tag container needs to be positioned at the top right corner of the main content container, pushed over a bit from the right and where the top border of the main container splits the tag container in half. Below, I have been able to more or less do so. But my question is how can I ensure that the top border of the main container perfectly coincides with the center of the tag container?
Including a link to the codesandbox for convenience.
<div className="main">
<div className="tag">TAG</div>
<p>MAIN CONTENT</p>
</div>
.main {
height: 150px;
width: 350px;
border: 1px solid black;
border-radius: 16px;
display: flex;
justify-content: center;
align-items: center;
position: relative;
}
.tag {
height: 20px;
width: 100px;
border: 1px solid green;
border-radius: 8px;
position: absolute;
top: -12px;
right: 24px;
z-index: 999;
background-color: green;
}
When you have a div with position: relative explicitly, then other divs inside it will be relative to it.
By applying position: absolute to the child div you will produce that it will be at the position (0, 0) of the parent container (counting from top-left). Then, if you apply top: height/2 to your child container, you will assure that it will always be centered with the top border of your parent container. Check the snippet below.
.container {
margin-top: 40px;
}
.parent {
height: 200px;
width: 320px;
background-color: orange;
position: relative;
}
.child {
height: 40px;
width: 80px;
position: absolute;
background-color: red;
top: -20px; /* must the half of the height.*/
right: 10%;
}
<div class="container">
<div class="parent">
<div class="child"></div>
</div>
</div>
Hope it helps you.
I would like to use an htmlcanvas a canvas as the background of a webpage and then have various Vuejs components rendered on top of it.
I am sure the information is out there I just don't know what to search.
You can style any element using CSS with position: absolute to overlay the element on top of the canvas.
.container {
position: relative;
width: 300px;
height: 300px;
}
.canvas {
width: 300px;
height: 300px;
background-color: yellow;
}
.overlay {
position: absolute;
left: 20px;
top: 20px;
width: 100px;
height: 100px;
background-color: orange;
}
<div class="container">
<canvas class="canvas"></canvas>
<div class="overlay">
This is displayed on top of the canvas
</div>
</div>
I'm trying to position a "seeker" in a div element that has other elements in it. I want the seeker to be able to move on top of the content div, without pushing other content around, while also following the scrollbar. The area is resizable so I can't use constant width/height. Like the seeker in a video editor would.
This is what I've gotten so far
#container {
width: 200px;
height:100px;
background-color: gray;
overflow: scroll;
}
#content {
width: 300px;
height: 120px;
}
#box {
width: 40px;
height: 40px;
background-color: green;
}
#seekerContainer {
position: relative;
width: 100%;
height: 100%;
}
#seeker {
width: 4px;
height: 100%;
position: relative;
background-color: blue;
left: 10%;
}
<div id="container">
<div id="content">
<div id="seekerContainer">
<div id="seeker"></div>
</div>
<div id="box"></div>
</div>
</div>
And I've tried different combinations having the seekerContainer and seeker be position absolute/relative, but either the seeker wont follow the scrolling, or it extends the height of the div.
Any pointers to fix this?
I think this is what you are looking for:
.container {
width: 200px;
height: 100px;
background-color: gray;
overflow: scroll;
}
.content {
height: 500px;
position: relative;
}
.box {
width: 40px;
height: 40px;
background-color: green;
}
.seeker {
width: 4px;
height: 100%;
position: absolute;
background-color: blue;
left: 10%;
top: 0;
}
<div class="container">
<div class="content">
<div class="seeker"></div>
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
</div>
</div>
Also, you don't want to put id on every element and use id for styling. You should use classes for that. ID of the element has to be unique for the page so it's not very useful when you need to apply the same styling to more elements.
I'm trying to make a fixed box with 980px width and 500px height scrolling inside a div with 100% width and 1500px height, but it is not working at all.
That's what I did: https://jsfiddle.net/zjuyuhmz/2/embedded/result/
The box is moving when the page scrolls, and I want to make scroll only if the mouse is inside of the div.
Is this possible??
Html:
<div id="wrapper">
<div class="main">
<div class="container">
<div class="container2">
<div class="test"></div>
<div class="test"></div>
<div class="test"></div>
</div>
</div>
</div>
</div>
Css:
#wrapper {
position: relative;
width: 100%;
height: 100%;
color: #a3265e;
font-family: 'GillSans-SemiBold';
}
.main {
border: 1px solid red;
position: relative;
width: 100%;
height: 100%;
margin: 0 auto;
padding-top: 380px;
}
.container {
border: 1px solid green;
position: relative;
width: 100%;
height: 500px;
margin: 0 auto;
overflow: scroll;
}
.container2 {
height: 1500px;
margin: 0 auto;
}
.test {
width: 940px;
height: 500px;
position: fixed;
left: 50%;
margin-left: -480px;
background: black;
}
You need to write javascript code, where you can get cursor position and depending on that enable scroll event.
Replace the css for .test for this:
.test {
width: 940px;
height: 500px;
position: absolute;
left: 50%;
margin-left: -480px;
background: black;
}
.test:focus {
position:fixed;
}
This means: when the element with id "test" has the focus on, make it's position fixed. If not, make it's position absolute.
Here is my tricky problem. I'm trying to do this:
http://www.hostingpics.net/viewer.php?id=767312test.gif
(More clear than an explication I think).
My structure :
<header></header>
<div class="section">
<div class="text"></div>
<div class="content"></div>
<div class="img"><img src="img1.png"/></div>
</div>
<div class="section">
<div class="text"></div>
<div class="content"></div>
<div class="img"><img src="img2.png"/></div>
</div>
<div class="section">
<div class="text"></div>
<div class="content"></div>
<div class="img"><img src="img3.png"/></div>
</div>
<footer></footer>
Important informations :
"Header" is fix
"Content" fit to the screen less the height of header
Every "section" are the same but with different content
When the image comes to an end, the "content" div is unfixed.
I am using "section" for implementing a next and previous button in the header (with anchors).
My problem is the scrolling part. I am really lost when I try to fix the "content" div. I don't know how to fix everything except the scroll of the image in the active "img" div when the active "content" div hits the header. (Everyone follows? Look here : http://www.hostingpics.net/viewer.php?id=767312test.gif
For the scrolling part in the "img" div, I was thinking use a sort of "overflow:scroll" but the scrollbar is really awful.
I don't know if it's enough clear. If there is any problem I can complete my problem. I am not very comfortable with complex structures in html with JS.
Thanks for your help!
This is pretty close to what you're asking for (using CSS only).
This relies on the fact that the backgrounds are solid colors. It uses various specifically-defined height properties as well that match some padding properties.
The .top-bar and .bottom-bar elements can probably be changed to pseudo elements if you don't want the extra HTML.
HTML:
<header>Header</header>
<div class="top-bar"></div>
<div class="bottom-bar"></div>
<div class="section">
<div class="text">Section 1 Text</div>
<div class="content">
<div class="img"><img src="http://placekitten.com/100/1000"/></div>
</div>
</div>
<div class="section">
<div class="text">Section 2 Text</div>
<div class="content">
<div class="img"><img src="http://placekitten.com/200/2000"/></div>
</div>
</div>
<div class="section">
<div class="text">Section 3 Text</div>
<div class="content">
<div class="img"><img src="http://placekitten.com/300/3000"/></div>
</div>
</div>
<footer>Footer</footer>
CSS:
body {
margin: 0;
padding: 100px 0 0;
}
header {
background-color: red;
height: 100px;
position: fixed;
top: 0;
width: 100%;
z-index: 10;
}
footer {
background-color: blue;
height: 100px;
}
.section {
min-height: 400px;
}
.text {
background-color: aqua;
height: 50px;
}
.content {
background-color: green;
min-height: 100%;
padding: 40px 0;
position: relative;
}
.img {
background-color: yellow;
min-height: 70%;
margin: 0 auto;
padding: 40px 0;
text-align: center;
width: 80%;
}
.img > img {
vertical-align: middle;
}
.top-bar, .bottom-bar {
background-color: green;
height: 40px;
position: fixed;
width: 100%;
z-index: 5;
}
.top-bar {
top: 100px;
}
.bottom-bar {
bottom: 0;
}
footer, .text {
position: relative;
z-index: 6;
}
JSFiddle here.
For an almost completely correct solution, here is one with some jQuery involved.
New CSS:
body {
margin: 0;
padding: 100px 0 0;
}
header {
background-color: red;
height: 100px;
position: fixed;
top: 0;
width: 100%;
z-index: 10;
}
footer {
background-color: blue;
height: 100px;
}
.section {
min-height: 400px;
}
.text {
background-color: aqua;
height: 50px;
}
.content {
background-color: green;
min-height: 100%;
padding: 40px 0;
position: relative;
}
.img {
background-color: yellow;
min-height: 70%;
margin: 0 auto;
padding: 40px 0;
text-align: center;
width: 80%;
}
.img > img {
vertical-align: middle;
}
.top-bar, .bottom-bar {
background-color: green;
height: 40px;
position: fixed;
width: 100%;
}
.top-bar {
top: 100px;
z-index: 5;
}
.bottom-bar {
bottom: 0;
z-index: 7;
}
footer, .text {
position: relative;
z-index: 8;
}
.img-fix {
bottom: 40px;
height: 400px;
overflow: hidden;
position: absolute;
width: 100%;
z-index: 6;
}
jQuery:
$(document).ready(function(){
$(".content").each(function(){
$(this).append($(this).html());
$(this).find(".img + .img").wrap("<div class='img-fix'></div>");
});
$(window).resize(function() {
resizeImgFix();
});
resizeImgFix();
});
function resizeImgFix() {
$(".img-fix").height($(window).height() - $("header").height() - $(".top-bar").height() - $(".bottom-bar").height());
$(".img-fix").each(function(){
$(this).scrollTop($(this).prop("scrollHeight"));
});
}
JSFiddle here.
Note: It duplicates the .img element and its children. This could be memory intensive depending. However, it does make it work as intended without any visual lag or artifacts.
