I have a <embed> element inside a div that contains a .txt file and I want to set it to automatically fit the size of the txt files contents.
However none of the tips I found here seem to work.
height: 100% or auto does absolutely nothing.
<!DOCTYPE html>
<html>
<head>
<title>Testpage</title>
<style>
body {
background: #aaa;
}
div {
width: 800px;
background: white;
}
embed {
padding: 25px;
width: 750px;
height: 100%;
}
</style>
</head>
<body>
<div>
<embed src="file.txt">
</div>
</body>
</html>
Also using <object> instead of <embed> as suggested in many questions here doesn't change the behavior at all.
It can't be that hard to do something this basic in CSS?
You maybe can try to use the font-size property of CSS.
An example of usage with it:
embed {
font-size: *what you need here*;
width: 100%;
}
Otherwise you may wanna look into CSS properties in JavaScript, and read lines, length etc. of content and base of it and take the users screen width into fact for the best result!
EDIT:
You could use XMLHttpRequest, AJAX, jQuery aswell in JavaScript.
And then change font size based on length of content.

I am writing an HTML file and using a lot this:
<iframe src="blablabla" width=100% height=555 frameBorder=0></iframe>
Is it possible to somehow define myiframe such that I can set this width, height and frame border in the definition and then just do
<myiframe src="blablabla"></myiframe>
?
Yeah, You can. These Custom Components are called Web Components.
For More info, take a look at this. (To make things easy, you can switch to ReactJS).
But, In your case, Adding a CSS will apply the styling to every iframe element.
iframe{ width:100%; height:555px; }
Implementation (Put style tag after head tag) -
<style>
iframe{
width:100%;
height:555px;
}
</style>
<body>
<iframe src="blablabla" frameBorder=0></iframe>
</body>
Is it possible to somehow define myiframe such that I can set this
width, height and frame border in the definition and then just do
<myiframe src="blablabla"></myiframe> ?
Yes, it is.
And though WebComponents are an incredibly powerful tool (and I very much hope they will continue to increase in popularity), in this situation you just need CSS:
Working Example:
.myiframe {
width: 200px;
height: 180px;
border: 3px dashed red;
}
<iframe class="myiframe" srcdoc="blablabla"></iframe>
The simplest way to start with CSS is go to the <head>...</head> of your HTML Document and add the following, somewhere in the document head:
<style>
.myiframe {
width: 200px;
height: 180px;
border: 3px dashed red;
}
</style>
At first, the problem seemed to be that only my CSS file, which was linked into my HTML document, wasn't loading in the browser when opened, but then when integrating an image into the HTML document I found it also wasn't appearing in the browser when the document was opened (and I used Microsoft Edge, Chrome, and Firefox to open the document. All files are located in the same folder on my computer, and yet using relative paths to locate the files also seem to be doing nothing. The code looks as such. (Worth noting that I was messing around with both the background-image property in CSS and the tag in HTML to load the same file since neither seemed to work)
HTML Code:
<head>
<title>Quad Game Schedule</title>
<link type="stylesheet" rel="text/css" href="displaylayout.css">
</head>
<body>
<div class="fieldimg">
<img src="field.png" alt="Field Overhead Image">
</div>
<div class="F1">
<h2>Full Field Games</h2>
<ul>
<li>12:00 - TSPro vs Wings</li>
<li>12:45 - Team Evanston vs Bosnia</li>
</ul>
</div>
CSS Code (displaylayout.css):
body {
background-color: rgb(242, 242, 242);
color: red;
}
p {
color: red;
}
img {
align-self: center;
vertical-align: top;
}
.fieldimg {
height: 30%;
width: 45%;
background-image: image(field.png);
background-size: cover;
}
.F1 {
align-self: center;
float: left;
clear: none;
width: auto;
}
In the browser developer side bar, it says that there are no style properties for the webpage, which can't be true. I can always write the CSS into the HTML document, but the image is also an integral part of the end product and that won't load either. (Also maybe worth noting, with text-color for the p element and body used in CSS was merely for testing purposes)
Edit: this is the exact code for the test files I made that still don't work.
HTML:
<html>
<head>
<title>Test Webpage</title>
<link type="stylesheet" rel="text/css" href="test.css">
</head>
<body>
<h1>This is a test heading</h1>
<p>This is a test paragraph</p>
<img src="test.png" alt="Test Picture">
</body>
</html>
CSS:
h1 {
color: red;
font-size: 24pt;
}
p {
color: blue;
font-size: 12pt;
}
The image in the new folder for these test files was renamed as test.png.
Edit 2: I just found out that older files of mine that linked to external files still work, so the problem lies with the new files I make.
In your code you are trying to load the image twice, once as a background image for the div with class fieldimg, and once inside it in an ` tag:
<div class="fieldimg">
<img src="field.png" alt="Field Overhead Image">
</div>
.fieldimg {
height: 30%;
width: 45%;
background-image: image(field.png);
background-size: cover;
}
1.) The background image needs to have be defined like background-image: url(field.png), not like you did it ("image(field.png)")
2.) The height setting for .fieldimg (30%) won't work, because there is no container around it that has a height setting to which the 30% could relate. So this becomes 0px high and therefore won't be visible. To avoid this you can apply height: 100% to the body
If you fix both, you'll have to erase either the background image or the image tag, otherwise you'll get your image twice...
Your CSS contains an error that might be the cause:
.fieldimg {
height: 300px; /* set an absolute amount of pixels here instead of a relative number (which is relative to nothing) */
width: 45%;
background-image: url('field.png'); /* this is how you place images by setting a background image */
background-size: cover;
}
Reference
Also, remember that when not using relative paths in your CSS it is relative to the location of the .css file! So if using an image as a background image in a specific CSS folder, be sure the image is relative to that CSS file location.
I have a quick question, I'm making a simple html document, with an image that I want to fill the entire page.
For some reason, it wants to create a border around the image. I've tried border="0"; and padding 0px 0px 0px 0px;
Here is the code in which I have: (You can also check it out live if you prefer www.kidbomb.com/chefwannabe)
<!DOCTYPE html>
<html>
<head>
<title>Pre-Order Now!</title>
</head>
<body>
<img style="width: 100%; overflow:hidden;" src="http://www.kidbomb.com/chefwannabe/chefwannabepreview.png" />
</body>
</html>
Add the following CSS in your code. Default body will give some margin and padding. So better whenever you start new work, add this style in your css for getting the proper result.
body
{
padding:0;
margin:0;
}
Instead of using the img tag, set the background-image property of the body tag so it encompasses the entirety of the page.
body {
background-image: url("path/to/image.jpg");
height: 100%;
width: 100%;
}
I'm new to HTML and CSS in general. Please help me with the code. I cannot get the background-image to appear in my browser although i typed the syntax correctly. All i get is an orange box, with no alert.png image. I'm following an online tutorial btw: http://dev.opera.com/articles/view/31-css-background-images/#thecode
Edit 1: The image, html file and css file are all inside the same folder. Yet no success.
Edit 2: I used an unique css file name instead of a generic "style.css" (which i have several of them in my system) and it worked! Make sure there's no space between url and the parenthesis.
HTMl code:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html lang="en">
<head>
<link rel="stylesheet" type="text/css" href="style.css">
<meta http-equiv="Content-Type" content="text/html;
charset=utf-8">
<title>alert message</title>
</head>
<body>
<p class="alert">
<strong>Alert!</strong>
This is an alert message.
</p>
</body>
</html>
CSS code:
.alert {
width: 20em;
background-image: url(C:\Documents and Settings\USER\My Documents\alert.png);
background-color:orange;
margin: auto;
padding: 2em;
}
The url must be a string:
url("C:\Documents and Settings\USER\My Documents\alert.png");
I would guess it's a permissions issue, regardless you will most likely have problems with the URL being a file reference when you move this to a server, I would recommend moving your image into the same location (or better yet an image folder in the root of your site) as your html file and then modify your css to be this
.alert {
width: 20em;
background-image: url('/alert.png'); /* '/images/alert.png' */
background-color:orange;
margin: auto;
padding: 2em;
}
Another way of doing things is to put your text into a div, and set the image as the div's background image using css, like so:
<div class="alert">
<p>
<strong>Alert!</strong>
This is an alert message.
</p>
</div>
And, for the CSS:
.alert {
width: 20em; (Width of entire div, which includes text and bg image)
background-image: url('../alert.png');
background-color: orange;
margin: auto;
padding: 2em;
}
You can see the live JSFiddle example here: http://jsfiddle.net/Cwca22/TdDJY/
Also, in the code above, the background image will tile (repeat) both horizontally and vertically to fill the space of the div. In order to prevent this, you could make the div the same height and width as your background image, or put background-repeat: no-repeat in your css under the .alert class.
Hope this helps and good luck!
Please check your URL, if possible you can use firebug which is addon of firefox, which will definitely help you, by indicating if image has been loaded or not.
Else another solution would be give height to your alert class as follows
.alert {
width: 20em;
background-image: url('/alert.png'); /* '/images/alert.png' */
background-color:orange;
margin: auto;
padding: 2em;
height: /* height of image*/
}
First put your alert.png picture in the same folder as your html file.
Then try this in your CSS file:
body {
background: orange url("alert.png") no-repeat;
}
I think the problem was the "\" in \alert.png
Good luck!
In the original question he had in his css
background-image: url(C:\Documents and Settings\USER\My Documents\alert.png);
I ran into problems with a gallery page that had images as background thumbnails. Any image filename that had spaces would not appear. It was only the fact that one image happened to have underscores in place of spaces and that did appear that I was able to track it down. As there are spaces in his url, this could be the problem. I fixed my problem by using \ to escape any characters like spaces causing the problem. i.e.
A\ space\ in\ the\ filename.jpg
though this might not work in a Windows pathname!
If the image is in the same directory as the script he shouldn't need the full url anyway.
Does anyone know how can I control the image source from the CSS?
I need to be able to change the image src from the CSS. I have loop printing < img id=.. > tags, and for every id it different image. I want to be able to set the source by its id from the style css area.
Does anyone know how to do this?
This is not possible: The image's source is part of the markup, not CSS.
The only workaround would be having div elements with background-image properties instead. Those you could set from within the style sheet:
<div id="image1"></div>
#image1 { width: 100px; height: 50px; background-image: url(image.gif); }
However, with this method you lose all the img tag's advantages like
The ability to set an alt text
Resizing
Printing (most browsers don't print background images)
Search engine indexing (probably)
the only other alternative is by using JavaScript, but that obviously won't work if JavaScript is disabled, which makes it a no-no in my view.
This is now possible with CSS3 using the Content style.
I use this to swap images within a slider based on window size through media queries.
Edit: When I originally posted this, I was unaware that it only worked in Webkit at the moment. But I doubt it will take long before it gains more functionality across browsers.
HTML
<img class="img1" src="image.jpg">
CSS
#media (min-width: 768px) {
.img1 {
content: url(image.jpg);
}
}
#media (max-width: 767px){
.img1 {
content: url(new-image.jpg);
}
}
That is not possible with CSS.
However, this is very easy with Javascript:
document.getElementById("IdOfImage").src = "SourceOfImage";
You cannot really do that, however, if you do need to do that using CSS, you can do it for two images with the same size like this:
<style>
img {
width:0;
height:0;
display:block;
background: url('2.png') no-repeat bottom left;
padding-left:196px;
padding-bottom:187px;
}
</style>
<img src="1.png">
Only tested it in FF3.6 though.
I found this article that might be useful. It actually changes background of an image
here is the example in case website goes missing:
HTML
<html>
<body>
<div class="header">
<img class="banner" src="http://notrealdomain1.com/banner.png">
</div>
</body>
</html>
CSS
/* All in one selector */
.banner {
display: block;
-moz-box-sizing: border-box;
box-sizing: border-box;
background: url(http://notrealdomain2.com/newbanner.png) no-repeat;
width: 180px; /* Width of new image */
height: 236px; /* Height of new image */
padding-left: 180px; /* Equal to width of new image */
}
If you don't want to use backgrounds nor use javascript, you layer 2 images with different src on top of each other (using absolute positioning) and use CSS to hide one or another. Visually it will be the same then changing the src.
