div elements not working [duplicate] - html

This question already has answers here:
Why does this CSS margin-top style not work?
(14 answers)
Closed 7 years ago.
I have two div elements and nav > nav_1. When i add a margin-top:20px; to nav, nav goes down 20pxaccording to body which is correct.
But when i add this margin-top:20px;to nav_1,nav_1 goes down 20px with nav according to body.
why ? nav_1 element of nav and it should move according to nav.
In that question im looking for an explanation
.nav {
height: 500px;
width: 500px;
background-color: black;
margin-top:50px;
}
.nav .nav_1 {
height: 50px;
width: 50px;
background-color: blue;
margin-top:50px;
}
<div class="nav">
<div class="nav_1">
</div>
</div>

This is one case of "margin collapse" mechanism. In brief margin of parent and child elements are collapsed into single margin of size equals max of their corresponding margins. There are several ways to disable such a behaviour, e.g. adding border or padding to parent element. You can read more about that mechanism at mdn article.

You can use padding on nav and remove margin on .nav .nav_1
or
you can add display:inline-block in .nav .nav_1
.nav {
height: 500px;
width: 500px;
background-color: black;
}
.nav .nav_1 {
height: 50px;
width: 50px;
background-color: blue;
margin-top:20px;
display:inline-block;
}
<div class="nav">
<div class="nav_1">
</div>
</div>

Further to #Paul Kozlovitch answer, to fix this you can set the the parent display:inline-block (or float etc).
.nav {
height: 500px;
width: 500px;
background-color: black;
margin-top:50px;
display:inline-block;
}
.nav .nav_1 {
height: 50px;
width: 50px;
background-color: blue;
margin-top:50px;
}
<div class="nav">
<div class="nav_1">
</div>
</div>

How to remove the space between inline/inline-block elements?
(41 answers)
Closed 4 years ago.
When a div is next to another larger one in the same container, the smaller one stays at the bottom. I would like it to start from the top, any idea how to do that?
See the example below. I would like the red box to come all the way up, of course without using something like position-relative then just moving it up in px or em
Bonus points if someone can explain where the spacing between my boxes come from since I did not specify any padding or margin ;)
.container {
background-color: blue;
width: 700px;
height: auto;
}
.small {
width: 200px;
height: 200px;
display: inline-block;
background-color: red;
}
.big {
height: 400px;
width: 400px;
display: inline-block;
background-color: green;
}
<div class=container>
<div class=small></div>
<div class=big></div>
</div>
vertical-align works on elements that are display: inline-block; - so simply add vertical-align: top;
As for the spaces, that's the "whitespace" between your elements, which exists because the divs are on separate lines. There's a handful of solutions to this, one of which is simply keep the closing </div> and opening <div> immediately adjacent (like so: </div><div>), which I have implemented in the snippet below.
.container {
background-color: blue;
width: 700px;
height: auto;
}
.small {
width: 200px;
height: 200px;
display: inline-block;
vertical-align: top;
background-color: red;
}
.big {
height: 400px;
width: 400px;
display: inline-block;
vertical-align: top;
background-color: green;
}
<div class=container>
<div class=small></div><div class=big></div>
</div>
The best solution to problems of container and child item layout is CSS Flexbox. Note that I added display: flex and align-items: flex-start to your container. That second one has the magic which aligns all child items to the top. Follow the link above for a very helpful reference. Also note that your spacing issue is fixed.
.container {
background-color:blue;
width: 700px;
height: auto;
display: flex;
align-items: flex-start;
}
.small {
width:200px;
height:200px;
display:inline-block;
background-color:red;
}
.big {
height: 400px;
width:400px;
display:inline-block;
background-color:green;
}
<div class=container>
<div class=small></div>
<div class=big></div>
</div>
There may be a better solution out there, but if you float each element left it will give you your desired output.
.container {
background-color: blue;
width: 700px;
height: auto;
}
.small {
width: 200px;
height: 200px;
display: inline-block;
background-color: red;
}
.big {
height: 400px;
width: 400px;
display: inline-block;
background-color: green;
}
.left{
float: left
}
<div class="container left">
<div class="small left"></div>
<div class="big left"></div>
</div>
Just add vertical-align: top; to both elements.
Also the space is added because both elements are inline-block and are considered as text elements, you can fix that by setting font-size to 0 to the parent element, like that:
.container{
font-size: 0;
}
And don't forget to set the right font size to the child elements if you're going to add some text to them, example :
.small, .big{
font-size: 16px;
}

height: 100% not working [duplicate]

This question already has answers here:
Why doesn't height: 100% work to expand divs to the screen height?
(12 answers)
Closed 5 years ago.
I'm trying to create a div (Menu) with a width of 20% of my screen and a height of 100% but the div does not display on the screen. I do not know why. Here is my code:
#Menu {
display: inline-block;
background-color: black;
min-width: 20%;
min-height: 100%
}
#Bar {
float: right;
background-color: blue;
width: 80%;
height: 100%;
margin: 0;
float: left;
}
<div id="Menu">Menu</div>
<div id="Bar">Bar</div>
Since your div elements are empty, they will collapse to 0 height. A height of 100% does not help in this case.
You will find that you can display your elements if you include a min-height property.
I have made some modifications to get it to work, together with some fine-tuning. I always indent my real code, but I have left the modifications un-indented so that you can see them more easily.
#Menu {
display:inline-block;
background-color : black;
min-width:20%;
min-height:100%;
margin: 0;
min-height:10px;
float: right;
}
#Bar {
float:right;
background-color : blue;
width:80%;
height:100%;
margin:0;
float:left;
min-height: 10px;
}
<div id="Menu">
</div>
<div id="Bar">
</div>

positioning items in html/css

I'm trying to learn some basics of HTML by using jfiddle. This is what I've done.
https://jsfiddle.net/Lqn0jch3/
HTML
<body>
<div class="container">
<div class="sidebar">
<div class="logo"></div>
<div class="menu-options">
<p>yeeeeeep</p>
</div>
</div>
</div>
</body>
CSS
html, body {
height: 100%;
overflow-y: hidden;
}
.container {
background-color : #458748;
height: 100%;
}
.sidebar {
height: 100%;
width: 30%;
background-color : #000000;
}
.logo {
background-image: url("https://upload.wikimedia.org/wikipedia/en/thumb/3/31/Britannia_Industries_Logo.svg/1280px-Britannia_Industries_Logo.svg.png");
background-size: contain;
background-repeat: no-repeat;
background-position: center;
height: 30%;
width: 100%;
text-align: center;
background-color: aqua;
}
.menu-options {
background-color: #FFFFFF;
}
p {
color: #000000;
}
But I can't understand why my 'menu-options' class is not being positioned just below the logo and there's some separation between them.
Thanks in advance.
is this what you want?
https://jsfiddle.net/Lqn0jch3/1/
i changed the css of p
p {
display: inline-block;
color: #000000;
}
the element <p> becomes margins by default, so changing its display or setting margin: 0px; would do the job for you
I've changed your class, modify the positioning to your needs:
.menu-options {
background-color: #FFFFFF;
position:relative;
top:-20px;
}
By default the browser adds margin to the top and bottom of the paragraph element, so to fix this you just have to change the margin to 0.
p {
margin: 0;
}
And you normally wouldn't use a paragraph element in a menu. An Unordered list works well. <ul> <li>
Separation between them is because of default margin style on element p
You can get diffrent default margin values on diffrent browsers, try using CSS Reset scripts.

}
could any one help me please
This is almost what you want. http://jsfiddle.net/
You need to be careful about a number of things.
work_nav and testimonial need to be in a separate div which I have included (container2)
The total width needs to be adjusted. I have changed it as well. You can play with it to make it according to what you need.
I have included borders as well to recognize each box. You should remove those borders and the width taken by the borders must be subtracted from the total current width. That means adjust the current width again.

Advanced table-layout to CSS

I have gotten the assignment to code a website from tables to CSS. While this is easy I have one question on how to recreate one of the site's biggest detail.
Site is: www.optimizer.dk.
How can I recreate the labels coming out of the left side, while still having the content in the middle?
Rest of the site is no worries.
Is the solution to:
padding-left: 200000px;
margin-left: -200000px;
To fake the expansion to the left?
I would possibly do it like this:
Live Demo
CSS:
html, body {
margin: 0;
padding: 0;
border: 0;
overflow-x: hidden
}
body {
background: #eee
}
#container {
width: 300px;
margin: 0 auto;
background: #bbb;
}
li, li span {
height: 25px;
}
li {
position: relative;
width: 200px;
background: #777
}
li span {
display: block;
position: absolute;
width: 9999px;
left: -9999px;
top: 0;
background: url(http://dummyimage.com/50x30/f0f/fff)
}
HTML:
<div id="container">
<ul>
<li><span></span>Menu Item</li>
</ul>
<div id="content">
Hi!
</div>
</div>
This answer was based on an older answer I wrote: 'Stretching' a div to the edge of a browser
Ideally here you would want a fluid width. See: http://jsfiddle.net/cbNvn/1/
<div id="left">Left</div>
<div id="center">Center</div>
<div id="right">Right</div>
div {
float: left;
}
#left {
width: 25%;
text-align: right;
}
#center {
width: 50%;
}
#right {
width: 25%;
}
Expanding the page would expand the left column and the background image can repeat. The linked images can lay over the background as they do currently. The text-align:right attribute will keep the linked images on the right.
You need 3 divs with float:left to create the 3 columns
i would put it all in a div and set position:absolute;. then put your buttons in there own divs so you can move them.
or
put it all in a div and set the margin to -5%(mite need to play with this into it works). then make the image the background and put you text buttons in there own div's so you can move then to where you want them.
Then use float:left; to line them up
