Background Image Issues - Set height? - html

I'm setting a background image on a page, but for some reason, the image is ONLY showing if I had a height. I don't want to set a fixed height though.
Any thoughts?
<div class="thinkBPG content"></div>
CSS:
.thinkBPG.content {
background: url(./home-blueprint.png) no-repeat center center fixed;
}

Ignore this.
I needed to remove the center center fixed.
I told you it was something silly.

The issue is because the content within that div is floated, so you need to tell the browser you want that div to contain it's floated contents. There are a few ways to handle this...you can float that div, you can put overflow on it, or you can use a clearfix solution.
Simplest way without introducing a lot of new code is to simply take off the height, and then add
float: left;
width: 100%;

Add image to the bottom of a adjustable height section

I am trying to created a CSS design on my web app. I am going for a banner that is flapping in the wind. I want the banner to expand/scroll its height so all text will be displayed on the banner but regardless of how tall the banner is, I want to add a ripped section of the banner at the bottom of it. The banner will be the same width in all cases.
Something like the example below (forgive the horrible Paint screenshot):
I can't seem to wrap my brain around how to accomplish this. Any of you smart people have any ideas?
First, I think it'd be helpful if you could provide an example of what you have so far. For example, what's your HTML & CSS for the adjustable-height divs, just without the image at the bottom? Easier to add onto that.
I believe the best way would be to add an image element at the bottom of your adjustable element (assuming it's a <div>). Position it as absolute, and set it relative to the bottom of its parent container. You may have to fiddle with it a bit to get it to work. Don't forget to also set the position of the parent to relative.

Good further reading on position: https://developer.mozilla.org/en-US/docs/Web/CSS/position
Give the container element "position:relative" (to create a new positioning context) and some bottom padding (to make space for the image). Then you can either use a background image set to be at the bottom of the container and not repeat vertically or absolutely position an image to the bottom.
You can use pseudo-elements for this. This way you don't require extra markup for each element.
.myDiv {
position: relative;
}
.myDiv::after {
content: url(image.jpg);
display: block;
position: absolute;
left: 0;
top: 100%; /* will be placed immediately where the div ends */
width: 100%;
}
Based on the height of the 'banner curls', set a margin-bottom on .myDiv.
Or directly, without absolute, as long as you don't have paddings:
.myDiv::after {
content: url(image.jpg);
display: block;
width: 100%;
}

Properly position footer

I am trying to position a footer under #cont, but inside the #container.
I tried making it so that when there is more content in #content, it would keep the footer inside the div, and allow me to scroll the page, but I got lost. Any idea how I should do it?
http://jsfiddle.net/a9jv7/
As you can see, more content will push it down(because it's not inside the other div, but if it's not inside, I can't set the footer to always be on the bottom of the page)
You can change the floating elements to display: inline-block, so you have more control over them and the container will adapt to their height.
#footer {
background-color:#FFA500;
text-align:center;
max-width:960px;
width: 100%;
}
The example: http://jsfiddle.net/frapporti/TPbCG/
EDIT:
In general, I'd really like to advice you against the use of floating elements for layout, as they were pushed beyond they original intended use from the very beginning, and now we have flex who does magic :)

If I understood what you want to achieve correctly, than this is one way to do it:
http://jsfiddle.net/a9jv7/1/
On #container add:
border-bottom:30px solid transparent; // used to add spacing bottom
margin-bottom:-30px; // used to add spacing bottom
overflow:hidden; // to give the container height, because it has none since the elements inside it are float-ed; (google clear-float).

Tiling an image over a whole page when I am already using the background

I have set up some background div's to theme a blog I am making. I am using 3 colors for the heading, a grey background, and I am wanting to add a texture to the background. I have the semi transparent image I want to tile, but I am not sure of the best way to have this work. I do NOT want position: fixed; on the div containing the image, so that it will move as you scroll.
Example code:
http://jsfiddle.net/YPXmT/
Is there a way to achieve this while not having scroll bars? (Note, I don't want to get rid of scrollbars, as content may require scrolling.)
Going from your example fiddle, you were most of the way there. All you have to do is make your backgroundTexture div height and width 100% instead of the static pixel values you used:
#backtexture {
position: absolute;
overflow: hidden;
width: 100%;
height: 100%;
background : url('http://static.tumblr.com/wyzt2fm/Hq8mhgfry/hp_asset_diagonalline.png');
}
MORE SIMPLE UPDATE:
Simplicity is best most times.
All you should need to do is add:
body{
position: relative
}
Don't bother making the container div and rearranging the elements as below, just making the body's position relative should fix this for you.
UPDATE: (Use update above, keeping this for posterity)
As per the comments below, with the code above any content that makes the window scroll beyond the visible space will not include the background. This is because the div is set to position: absolute and height/width: 100%. The div is getting sized to the size of the viewable space, but any content that extends beyond that will cause the background div to look like it has stopped. To fix this problem you just need to tweak your HTML and CSS a little bit more. Instead of the CSS above use:
#backtexture {
width: 100%;
height: 100%;
background : url('http://static.tumblr.com/wyzt2fm/Hq8mhgfry/hp_asset_diagonalline.png');
}
Notice we removed the position:absolute and overflow:hidden. Next we change the HTML so that the background isn't just an empty div placed on the page, but instead used as a container for all other elements on the page:
<div id="backtexture">
<div id="redtop"></div>
<div id="orangetop"></div>
<div id="yellowtop"></div>
<div id="wrapper">
</div>
And that should do it.

How do I make a header that remains in the top at all times?

I want to make a header like http://www.chacha.com (doesn't move, is about that wide and that height, and able to fit divs inside it and also has to be an image)
I am starting off with a blank html document and a blank css page, so there I haven't currently written any code.
I've been trying two days straight to do this now so I would really appreciate any help anyone can provide.
I have gimp so if anyone could also give me image dimensions for a perfect header and perfect background size I would appreciate it even more.
CSS:
#header {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 10px;
background: url(yourimage.png) repeat-x;
}
<!--html -->
<div id="header"></div>
That should give you a starting place, I can't tell you more without seeing exactly what the layout's supposed to be.
The CSS property you're looking for is position: fixed which will position the element relative to the viewport. This is good breakdown of positioning: https://developer.mozilla.org/en-US/docs/CSS/position
In this specific case, what you've got is an element with styles roughly along these lines:
#header_id {
position: fixed;
width: 100%;
height: 35px;
}
You don't have to set the height, but unless there is content in the fixed element, it will collapse if there is no height specified. They also appear to have put a drop-shadow on the element toget the neat floating effect.
If you want to have an image inside, you can just put the <img> inside the header element, or use it as the background-image url in the CSS and position it with background-position (see also: https://developer.mozilla.org/en-US/docs/CSS/background-position although the compatability table at the bottom is important if you want to do anything too specific with this property).
You can do this with any block-level element (or any element with display:block set on it). In your example they are using the HTML5 <header> tag; a <div> would work, too, if <header> wasn't appropriate for your page.
I would recommend using the Firebug addon with Firefox (or similar developer consoles with other modern browsers) -- you can right click on an element on the page and select 'Inspect element' from the dropdown menu and get a breakdown of both the markup and styling to see how other websites are constructed. Very useful for when you're browsing the internet and you see something and think, 'that's a neat trick, how does it work?'
FOR FULL WIDTH FIXED HEADER
header {
width:100%;
background:green;
height:60px;
margin:-8px;
position:fixed;
}
FOR NONFULL WIDTH FIXED HEADER
Create a div and set width and height (you can also set it left or right by float:left, float:right)
then in this div put the code above but without margin:-8px; and change the width to the width that your div has.

CSS HTML figure padding

I am trying to use CSS and HTML to insert an image into a webpage.
I have the following on CSS:
#eDTP {
background-image: url(eDTP.png);
background-repeat: no-repeat;
background-position: center;
padding-top:475px;
}
and in my HTML, I have:
<div id="maintext">
<p> my page </p>
</div>
<div id="eDTP"></div>
Although this works, I have a big white space on the top and bottom of the images, which I do not want. I tried adjusting the padding values, but that does not seem to really help.
Could anyone please point me in the right direction to get rid of these white spaces?
I would remove the padding top. That should eliminate the problem. I'm not sure why you would need such a high amount of padding between them.
EDIT - Just read that you say the padding hasn't helped you. Any chance of a link to the url? Or a live example somewhere to see the issue in more detail?
Make sure that the line-height of the figure or surrounding element is set to line-height:1;
The only size that you have specified is the padding. The size of a background image doesn't affect the size of the element. You should remove the padding, and specify width and height for the element so that it's the same size as the image.
Unfortenately there is no way to do that in HTML/CSS. Only way of doing this is inserting the values on your server or client-side by javascript. You should really do it with <img> tags inside your <div> element like so.
Make sure you point to the right location of the image you want to show relevent to folder where it is being called.
http://jsfiddle.net/gKFAT/
Here you try to show an image as a background for a div. Is there really strong reason not to use html like above?
<div id="maintext">
<p> my page </p>
</div>
<div id="eDTP">
<img src="eDTP.png">
</div>
If so, you need to specify the dimentions of your di, 'cause it doesn't auto fit the background size (no surprise here, I think).
Try
#eDTP {
background-image: url(eDTP.png);
background-repeat: no-repeat;
background-position: center;
width: 120px; //background image width here
height: 150px; // and height here
}
Your biggest problem is width and height. Also, how do you want this image displayed? Do you want it below the text, on the side of the text, etc? In modern browsers, a div is fully collapsed, and its height is equal to 0. Its width, by default, is 100%. IE7 and older does not work this way for the height.
You need to specify, not padding, but width and height for your div container, eDTP, that is, if you wish to have the background image added via CSS. If you wish to have an image populate eDTP using the img tag, then you do not have to specify the height.
By the way, the reason you see your image with the padding is based on something called the box model. Padding extends the visible region of background color, a background image, and others. The padding you have is functioning like you have a height assigned to its container. But as I said before, this is a very bad way to do this. Add this to your eDTP declaration:
#eDTP {
background: url(eDTP.png) no-repeat center;
width:500px; /* Change this value to the width of your image */
height:475px;/* I assume this is the height of your image */
}
