I actually wrote here a whole page of text, but it was impossible to understand and putting a jsfiddle is just easier for you guys.
here it is: http://jsfiddle.net/pMdZK/
the problem is links dont work, if they do hovers doesnt work and I have tried solutions like clearfix.
Both "container" and "default" divs are essential to me and they are actually 2 images that meant to overlap each other(one is half-transparent, gif image with some parts missing. that is to change that image later for other stuff, while user is in page.)
also changing
position:absolute
doesnt seem to do much either.
Changing the padding-top of all items into margin solves your problem. The reason is that padding extends the entire entity while margin pushes the other entity's away.
http://jsfiddle.net/pMdZK/1/
You had:
#containerx #pl6
{
padding: 521px 0 0 120px;
position: absolute;
font-size: 22px;
}
You need:
#containerx #pl6
{
margin: 521px 0 0 120px;
position: absolute;
font-size: 22px;
}
change this for every item ofc.
The difference between margin and padding:
Margins and padding can be confusing to the novice Web designer. After all, in some ways, they seem like the same thing: white space around an image or object.
Padding is the space inside the border between the border and the actual image or cell contents. In the image, the padding is the yellow area around the contents. Note that padding goes completely around the contents: there is padding on the top, bottom, right and left sides.
Margins are the spaces outside the border, between the border and the other elements next to this object. In the image, the margin is the red area outside the entire object. Note that, like the padding, the margin goes completely around the contents: there are margins on the top, bottom, right, and left sides.
To further explain the difference i made a quick jsfiddle.
http://jsfiddle.net/GRLkt/
The padding box expands the entire div. (as you can see by the background image).
The margin box pushes the other content away.
I have three divs: header, left and right, and I am using border-right to add a line separating the two divs. The problem that I am having is that the border only spans the length of the content and not the entire page. How can I make the border extend to fill the entire page?
.leftdiv{
width:36.5%;
border-right:1px solid #222222;
float:left;
}
The problem is that the div will only grow to be as large as the content inside of it needs it to be. The border is just a visual cue to that.
You could throw a min-height on the div to make it extend as far as you want it.
The other solution would be to create faux columns, but your best bet may be in this article:

I have a grid of tiles, what I want to be able to do is hover a tile and add a 3px border and keep the tile positioned correctly without disrupting the other tiles around it. At the moment I'm not completely sure how this can be achieved? Can this be achieved using floats or would I have to absolutely position each of the tiles and then increase the z-index of the hovered tile so it stands out above the rest?
Also the tile dimensions have to remain the same and the border has to be outside the tile and not inset.
Fiddle here: http://jsfiddle.net/Z7TwF/
On the :hover selector you need to remove the combined width of the borders:
li:hover{border:3px solid #f00; width: 44px; height: 44px;}
When you add a border to an element, it increases its dimensions. So when you hover the element, removing the combined width of the borders on the dimension attributes will fix the issue.
http://jsfiddle.net/Z7TwF/2/
Another solution is to change the box-sizing method:
li
{
box-sizing: border-box;
}
This in essence tells the browser to calculate the width of the borders in with the width of the element, preventing the offset you had in your original example.

I have 2 columns, floated one to each side, and I'd like to use a 1px width line separator, that goes from top to bottom of the longest column.
Id rather stay away of TABLE layouts, and I dont know which one will be the longest column, or how long will it be.
How could I do this with just css?
http://jsfiddle.net/AhfXc/2/
Something like this
.colright{
float: right;
border-left: 1px solid gray;
left: -1px;
position:relative;
}
http://jsfiddle.net/AhfXc/18/
You could fake it by putting a parent div around both and giving the parent a background image which would be a 200px wide, 1px high image with the a 1px black/gray dot in the middle.
This is possible with CSS. Here's my version of your example: http://jsfiddle.net/AhfXc/15/
Basically, just make the separator be absolutely positioned within the parent container (make the parent position relative so this works). Then attach the child to the top and bottom with top: 0 and bottom: 0. You could set the separator background to be the colour you want, but I've used a border style since you could easily apply dashed/dotted style if you want to.
This does only works if the columns have a known absolute or relative width because the separator's horizontal position is not directly affected by them, but if this is the case, it's a fairly simple solution.
What is the difference between margin and padding in CSS?
In what kind of situations:
both work.
only margin is appropriate.
only padding is appropriate.
TL;DR: By default I use margin everywhere, except when I have a border or background and want to increase the space inside that visible box.
To me, the biggest difference between padding and margin is that vertical margins auto-collapse, and padding doesn't.
Consider two elements one above the other each with padding of 1em. This padding is considered to be part of the element and is always preserved.
So you will end up with the content of the first element, followed by the padding of the first element, followed by the padding of the second, followed by the content of the second element.
Thus the content of the two elements will end up being 2em apart.
Now replace that padding with 1em margin. Margins are considered to be outside of the element, and margins of adjacent items will overlap.
So in this example, you will end up with the content of the first element followed by 1em of combined margin followed by the content of the second element. So the content of the two elements is only 1em apart.
This can be really useful when you know that you want to say 1em of spacing around an element, regardless of what element it is next to.
The other two big differences are that padding is included in the click region and background color/image, but not the margin.
div.box > div { height: 50px; width: 50px; border: 1px solid black; text-align: center; }
div.padding > div { padding-top: 20px; }
div.margin > div { margin-top: 20px; }
<h3>Default</h3>
<div class="box">
<div>A</div>
<div>B</div>
<div>C</div>
</div>
<h3>padding-top: 20px</h3>
<div class="box padding">
<div>A</div>
<div>B</div>
<div>C</div>
</div>
<h3>margin-top: 20px; </h3>
<div class="box margin">
<div>A</div>
<div>B</div>
<div>C</div>
</div>
Margin is on the outside of block elements while padding is on the inside.
Use margin to separate the block from things outside it
Use padding to move the contents away from the edges of the block.
The best I've seen explaining this with examples, diagrams, and even a 'try it yourself' view is here.
The diagram below I think gives an instant visual understanding of the difference.
One thing to keep in mind is standards compliant browsers (IE quirks is an exception) render only the content portion to the given width, so keep track of this in layout calculations. Also note that border box is seeing somewhat of a comeback with Bootstrap 3 supporting it.
There are more technical explanations for your question, but if you want a way to think about margin and padding, this analogy might help.
Imagine block elements as picture frames hanging on a wall:
The photo is the content.
The matting is the padding.
The frame moulding is the border.
The wall is the viewport.
The space between two frames is the margin.
With this in mind, a good rule of thumb is to use margin when you want to space an element in relationship to other elements on the wall, and padding when you're adjusting the appearance of the element itself. Margin won't change the size of the element, but padding will make the element bigger1.
1 You can alter this behavior with the box-sizing attribute.
MARGIN vs PADDING :
Margin is used in an element to create distance between that element and other elements of page. Where padding is used to create distance between content and border of an element.
Margin is not part of an element where padding is part of element.
Please refer below image extracted from Margin Vs Padding - CSS Properties
From https://www.w3schools.com/css/css_boxmodel.asp
Explanation of the different parts:
Content - The content of the box, where text and images appear
Padding - Clears an area around the content. The padding is transparent
Border - A border that goes around the padding and content
Margin - Clears an area outside the border. The margin is transparent
Live example (play around by changing the values):

It's good to know the differences between margin and padding. Here are some differences:
Margin is outer space of an element, while padding is inner space of an element.
Margin is the space outside the border of an element, while padding is the space inside the border of it.
Margin accepts the value of auto: margin: auto, but you can't set padding to auto.
Tip: You can use the trick to make elements centered inside their parents (even vertically). See my other answer for example.
Margin can be set to any number, but padding must be non-negative.
When you style an element, padding will also be affected (e.g. background color), but not margin.
Here is some HTML that demonstrates how padding and margin affect clickability, and background filling. An object receives clicks to its padding, but clicks on an objects margin'd area go to its parent.
$(".outer").click(function(e) {
console.log("outer");
e.stopPropagation();
});
$(".inner").click(function(e) {
console.log("inner");
e.stopPropagation();
});
.outer {
padding: 10px;
background: red;
}
.inner {
margin: 10px;
padding: 10px;
background: blue;
border: solid white 1px;
}
<script src="http://code.jquery.com/jquery-latest.js"></script>
<div class="outer">
<div class="inner" style="position:relative; height:0px; width:0px">
</div>
</div>
The thing about margins is that you don't need to worry about the element's width.
Like when you give something {padding: 10px;}, you'll have to reduce the width of the element by 20px to keep the 'fit' and not disturb other elements around it.
So I generally start off by using paddings to get everything 'packed' and then use margins for minor tweaks.
Another thing to be aware of is that paddings are more consistent on different browsers and IE doesn't treat negative margins very well.
The margin clears an area around an element (outside the border), but the padding clears an area around the content (inside the border) of an element.
it means that your element does not know about its outside margins, so if you are developing dynamic web controls, I recommend that to use padding vs margin if you can.
note that some times you have to use margin.
One thing to note is when auto collapsing margins annoy you (and you are not using background colours on your elements), something it's just easier to use padding.
Advanced Margin versus Padding Explained
It is inappropriate to use padding to space content in an element; you must utilize margin on the child element instead. Older browsers such as Internet Explorer misinterpreted the box model except when it came to using margin which works perfectly in Internet Explorer 4.
There are two exceptions when using padding is appropriate to use:
It is applied to an inline element which can not contain any child elements such as an input element.
You are compensating for a highly miscellaneous browser bug which a vendor *cough* Mozilla *cough* refuses to fix and are certain (to the degree that you hold regular exchanges with W3C and WHATWG editors) that you must have a working solution and this solution will not effect the styling of anything other then the bug you are compensating for.
When you have a 100% width element with padding: 50px; you effectively get width: calc(100% + 100px);. Since margin is not added to the width it will not cause unexpected layout problems when you use margin on child elements instead of padding directly on the element.
So if you're not doing one of those two things do not add padding to the element but to it's direct child/children element(s) to ensure you're going to get the expected behavior in all browsers.
First let's look at what are the differences and what each responsibility is:
1) Margin
The CSS margin properties are used to generate space around elements.
The margin properties set the size of the white space outside the
border. With CSS, you have full control over the margins. There are
CSS properties for setting the margin for each side of an element
(top, right, bottom, and left).
2) Padding
The CSS padding properties are used to generate space around content.
The padding clears an area around the content (inside the border) of
an element. With CSS, you have full control over the padding. There
are CSS properties for setting the padding for each side of an element
(top, right, bottom, and left).
So simply Margins are space around elements, while Padding are space around content which are part of the element.
This image from codemancers shows how margin and borders get togther and how border box and content-box make it different.
Also they define each section as below:
Content - this defines the content area of the box where the actual content like text, images or maybe other elements reside.
Padding - this clears the main content from its containing box.
Border - this surrounds both content and padding.
Margin - this area defines a transparent space that separates it from other elements.
I always use this principle:
This is the box model from the inspect element feature in Firefox. It works like an onion:
Your content is in the middle.
Padding is space between your content and edge of the tag it is
inside.
The border and its specifications
The margin is the space around the tag.
So bigger margins will make more space around the box that contains your content.
Larger padding will increase the space between your content and the box of which it is inside.
Neither of them will increase or decrease the size of the box if it is set to a specific value.
Margin
Margin is usually used to create a space between the element itself and its surround.
for example I use it when I'm building a navbar to make it sticks to the edges of the screen and for no white gap.
Padding
I usually use when I've an element inside a border, <div> or something similar, and I want to decrease its size but at the time I want to keep the distance or the margin between the other elements around it.
So briefly, it's situational; it depends on what you are trying to do.
Margin is outside the box and padding is inside the box
