Question
How can we center the <h1> tag within its container, and still keep the letterpress effect? Assume that we don't know in advance that the container's width is 500px. That is, a solution which hardcodes the position of the header is not acceptable. It's easy enough to center the header:
<div style="width:500px;text-align:center">
<h1 class="success-header" title="Success!">Success!</h1>
</div>
But this destroy's the letterpress effect:
The "shadow" is positioned absolutely with relation to its nearest eligible parent. You can make the immediate parent eligible by adding position:relative to it.
Example: http://jsfiddle.net/qkAJD/5/
.success-header {
color: green;
display: inline-block;
font-size: 50px;
height: 50px;
margin: 0;
position: relative; /* changed line */
}
Absolute - Do not leave space for the element. Instead, position it at
a specified position relative to its closest positioned ancestor or
to the containing block.
Source, emphasis mine.
Just add positon: relative to .success-header, since you already are positioning the shadow absolutely.
.success-header {
...
position: relative;
}

I want to absolute position a div but it is not sticked to the top but has a blank space. Container has position:relative and inner block has position:absolute css rules. I tried to play with the code and noticed that changing background-position has some effect and I have no idea why.
<header>
<div class="header-wrapper">
<div class="header-slogan-1 text-center">Base info</div>
<div class="header-info">Info</div>
</div>
</header>
What I want is to have the green block at the top (see fiddle).
Here is the fiddle
Please can anyone explain the behaviour and answer why the block is shifted from the top?
It is shifted from the top, because it is relative to its parent .header-wrapper, that has a top margin. In order to get the desired result, you have to remove position: relative from its parent, therefore it will be relative to the viewport and will be placed at the top.
Edit: I realised, that he margin is actually applied to the child of the wrapper, causing margin collapsing. In order to fix this, you need apply overflow: auto to the parent element. By doing that, you can still have a position: relative on the wrapper, as it is not pushed down by the child. Take a look at the demo:
/* header block */
header {
height: 536px;
background-color: #ddd;
background-position: center;
background-size: 100% 536px;
background-repeat: no-repeat;
overflow: hidden;
}
header .header-wrapper {
position: relative;
overflow: auto;
z-index: 2;
}
.header-slogan-1 {
font-size: 32px;
font-weight: 700;
font-style: italic;
margin-top: 88px;
}
.header-wrapper .header-info {
position: absolute;
top: 0;
z-index: 3;
background-color: #4caf50;
max-width: 600px;
padding: 25px 25px 25px 75px;
color: #fff;
}
.text-center {
text-align: center;
}
<header>
<div class="header-wrapper">
<div class="header-slogan-1 text-center">Base info</div>
<div class="header-info">Info</div>
</div>
</header>
If I'm understanding this correctly, you want the header to have no space around it. If this is the case, then just add
body {
margin: 0;
padding: 0;
}
to the top of your css and you should be all set.
I changed margin-top: 88px; into padding-top: 88px; of header-slogan-1 as it does not change my layout. I have an image in wrapper class and it is centered and may exceed the container size, so I need position:relative and overflow:hidden.
Finally I decided to pick my solution. Sorry Adam for not choosing your answer.
I need to use this shape and inside that shows a text. But, I don't know why the text is not showing.
HTML:
<div id="thebag">
<h3> Shihab Mridha </h3>
</div>
CSS:
#thebag{
position: relative;
overflow: hidden;
}
#thebag::before{
content: '';
position: absolute;
top: 0;
left: 0;
height: 50px;
width: 30%;
background: red;
}
#thebag::after {
content: '';
position: absolute;
top: 0;
left: 30%;
width: 0;
height: 0;
border-bottom: 50px solid red;
border-right: 70px solid transparent;
}
https://jsfiddle.net/kn87syvb/1/
You need to add position: relative (or position: inherit, since it's the same as the parent) to your #thebag h3 class. Currently, your CSS styles are only affecting the parent of the h3—in order for the h3 to show with the text, you need to define CSS styling for it.
https://jsfiddle.net/kn87syvb/2/
By setting a position:absolute to the #thebag::before you "broke" the flow and your text is behind your div. You have to precise, than the h3 tag will be relative depending it's container.
So you have to add this :
#thebag h3 {
position:relative
}
To precise all h3 on your #thebag section will be affected. Be careful, if you change your kind of selector, It won t work anymore.
May be it will be better to use a custom class, like this https://jsfiddle.net/kn87syvb/5/
You need to use postion:relative property:
#thebag h3{
postion:relative;
}
Small explanation:
position: relative will layout an element relative to itself. In other words, the elements is laid out in normal flow, then it is removed from normal flow and offset by whatever values you have specified (top, right, bottom, left). It's important to note that because it's removed from flow, other elements around it will not shift with it (use negative margins instead if you want this behaviour).
However, you're most likely interested in position: absolute which will position an element relative to a container. By default, the container is the browser window, but if a parent element either has position: relative or position: absolute set on it, then it will act as the parent for positioning coordinates for its children.

You can also re-structure your HTML and CSS as follows:
HTML
<span class="start">Shihab Mridha</span>
<span class="end"></span>
CSS
.end {
height:0;
width:0;
float: left;
display: block;
border:10px solid #0f92ba;
border-top-color:transparent;
border-right-color:transparent;
border-bottom-color:#0f92ba;
border-left-color:#0f92ba;
}
.start{
height: 20px;
width: 60px;
float: left;
background: #0f92ba;
display: block;
color:#FFFFFF;
}

I have a banner that I am trying to add a text to the bottom portion of it. I got the text centered and how I want to be, but when I want to move the text to the bottom of the page, the picture moves too.
HTML
<div class="col_one art-banner">
<div class="art-banner-text">
<h2>what do <span>you</span> want to learn?</h2>
</div>
</div>
CSS
.art-banner { background-image: url("graphics/art_banner.jpg"); height: 150px;}
.art-banner-text { width: 940px; height: 50px; background-color: rgba(0,0,0,0.5); }
.art-banner-text h2 { text-align: center; padding-top: 10px; font-family: "Bender";}
.art-banner-text span { color: #eb6623; }
JSFiddle
Presuming you're trying to use margin-top to move the art-banner-text down, you're running into the collapsing margin problem: the margin is shared between the inner div and the outer one, meaning the outer one gets the margin too.
So the solution is not to use margins, but position:relative for the outer div and position:absolute for the inner one, with bottom:0 to position it at the bottom of the outer one.
.art-banner {
background-image: url("https://photos-2.dropbox.com/t/2/AAAtS4UXAnyf0x4vH0ty5lE779vFfS2smjUWyJFsFwnMPg/12/18401260/jpeg/32x32/1/1437685200/0/2/art_banner.jpg/COyP4wggASACIAMgBCAFIAYgBygBKAIoBw/L9JVtmzn-g-n3CMbDujkZkXxzuwR9ntwvtEoBLNl_4g?size=1024x768&size_mode=2");
height: 150px;
position: relative;
}
.art-banner-text {
width: 940px;
height: 50px;
background-color: rgba(0, 0, 0, 0.5);
position: absolute;
bottom: 0;
}
.art-banner-text h2 {
text-align: center;
padding-top: 10px;
font-family: "Bender";
margin: 0;
}
.art-banner-text span {
color: #eb6623;
}
<div class="col_one art-banner">
<div class="art-banner-text">
<h2>what do <span>you</span> want to learn?</h2>
</div>
</div>
(Note that I had to change the URI for the image, to make it show up. What you had was the URI for the dropbox page that displays the image, not the image itself.)
You need to have the outer container ( which is .art-banner-text) set to position:relative; and set the inner div or element to absolute to place it where you want. https://jsfiddle.net/2ryrnxz7/
<div class="col_one art-banner">
<div class="art-banner-text">
<h2>what do <span>you</span> want to learn?</h2>
</div>
</div>
css
.art-banner { background-image: url("https://www.dropbox.com/s/migdkqlmse8ym0t/art_banner.jpg?dl=0"); height: 150px;}
.art-banner-text { width: 940px; height: 50px; position: relative; background-color: rgba(0,0,0,0.5); }
.art-banner-text h2 { font-family: "Bender"; margin: auto 0; padding:0px; bottom:0px; position:absolute; left:35%}
.art-banner-text span { color: #eb6623; }
You can set the left to whatever % you want to push towards the middle. This won't work for mobile as it is set and won't reposition itself with the page. But if you just need it to work for desktop, this is how to do it.
It sounds like you might want to use CSS positioning. For example .art-banner {position: relative;} .art-banner-text {position: absolute;} You can then position, move, or animate the text in the inner div without affecting the outer div.
I have a problem with a float which overflows (JSFiddle here).
HTML
<div id="father">
<div id="son">
gruik
</div>
<div id="dog">
gruikgruik gruik gruik gruikg ruik gruik gruikgr uikgruik gruik gruik gruik
</div>
</div>
CSS
div { border: solid; }
#father { width: 300px; position: relative; }
#father:after { content: ""; display: block; clear: both; }
#son { width: 100px; float: left; border: solid red; }
#dog { float: left; border: solid blue; position: absolute; left: 105px; }
As you can see, #dog overflows from #father. I tried classical CSS techniques but they just do not work (neither the clearfix method, nor overflow:hidden; or overflow:auto;).
I think the problem appears because of the use of the position CSS properties but I need it.
position: absolute; is correctly positioning the #dog element relative to #father (because #father has position: relative;).
However it is only the #son element which is giving #father its height. Elements positioned absolutely are taken out of the flow and therefore if #dog increases in height, its parent container (#father) will not, and therefore #dog looks to be overflowing.
Why do you have to use position: absolute; on #dog?
Can you not just use float, and set its width? You are setting its parent and siblings widths anyway so you know what width it should be (if you specify the width of the borders too).
DEMO: http://jsfiddle.net/sgw4K/5/
EDIT/UPDATE: After discovering additional styling, thirtydot has recommended two sound fixes to the problem. See comment below or the following:
To fix that, you can remove float: left from #son and then pick one of
these two choices: margin-left: 52px or overflow: hidden; on the #son element.
So I have three div's
One parent and two child.
The parent is as follows:
#parent {
overflow:auto;
margin: 0 auto;
margin-top:37px;
min-height: 100%;
width:875px;
}
the two child divs are as follows
#child1 {
overflow:auto;
min-height:150px;
border-bottom:1px solid #bbb;
background-color:#eee;
opacity:0.4;
}
#child2 {
height:100%;
background-color:white;
}
The parent div extends 100% as I can see the borders of it till the end of the page but the child2 is not extending down to the end of the page like the parent div.
height doesn't behave the way you seem to be anticipating. When you specify height: 100% that percentage is calculated by looking up the DOM for the first parent of said element with a height specified that has absolute or relative positioning.
You can cheat when it comes to the body tag, so if you had something like this:
<body>
<div style="height: 100%">
</div>
</body>
Some browsers/versions will behave the way you expect by taking up the total height of the page. But it won't work when you go any deeper than that.
Here is the approach I use to strech a div to the bottom of the page, it involves absolute positioning (nice thing about this one is that it is pretty cross-browser compliant and doesn't require javascript to pull it off):
<div id="parent">
<div id="childNorm"></div>
<div id="childStrech"></div>
</div>
#parent
{
position: absolute;
width: 1000px;
bottom: 0;
top: 0;
margin: auto;
background-color: black;
}
#childNorm
{
position: absolute;
width: 1000px;
top: 0;
height: 50px;
background-color: blue;
color: white;
}
#childStrech
{
position: absolute;
width: 1000px;
top: 50px;
bottom: 0;
background-color: red;
color: white;
}
Here is a Jsfiddle for demo: http://jsfiddle.net/t7ZpX/
The trick:
When you specify absolute positioning and then put in bottom: 0; that causes the element to stretch to the bottom of the page; You just have to worry about positioning the elements as a trade off.
Yes, this is one of the annoying things in css. min-height is not considered a "height" for purposes of calculating height. See http://jsfiddle.net/3raLu/3/. You need to have height: 100% on the parent div to make the child full height. Or, if you can have it be absolutely positioned, then this works: http://jsfiddle.net/3raLu/6/.
