I expect following code to put my span to the top-left corner of the button, but it doesn't. Why is that?
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<style type='text/css'>
</style>
</head>
<body>
<button style='height:100px;width:100px;position:relative;'>
<span style='position:absolute;top:0;left:0;'>text</span>
</button>
</body>
</html>
<span> is placed relative to the vertical-middle line (with 3px padding I can't explain).
Replacing <button> with <div> does places <span> at the top-left corner.
Question: why does absolute positioning within button (with position:relative) behaves differently from layout using <div>? And how do I fix it?
Background: I use two absolutely positioned div's within button to create a floating-width button with rounded corners.
EDIT: IMPORTANT IE 8.0 works exactly as I expect it (span in the top-left corner), the problem I see is in Firefox (3.6.6).
I advice against using a <button> this way. It is really difficult to style and you'll end up having to write specific styles for different browsers.
I needed to achieve something very similar and after dealing with a large amount of exceptions and fiddly positioning to accommodate different browser rendering, I went for this structure instead:
<div class="button">
<span>
<button>Text</button>
</span>
</div>
With the button tag reset this way:
button {
background:none repeat scroll 0 0 transparent;
border:0 none;
font-family:inherit;
font-size:inherit;
font-weight:inherit;
margin:0;
overflow:visible;
padding:0;
position:relative;
}
You can even use js to wrap the <button> on page load. This system has turned out to be much more solid and reliable. Requiring less css and almost no browser specific styling.
Update:
As I commented below, the wrapping element should not be an <a> tag. Remember that we need the <button> to keeps its functionality, we just need it to be text only (form will still submit on enter).
You can still re-use any css that you may be using to turn standard links into expandable button widgets only in this case it;s a <div> instead of an <a>.
Your problem is only with Firefox?? (3.6.6) - Can't fix it with standard CSS. Try:
button::-moz-focus-inner {
border: 0;
padding: 0;
}
That will do it for Firefox hopefully. Good luck!

I have a webpage that is a template from a company that design it for us and we have an admin panel which we can add content to the page.
This normally works fine but there is a specific page that doesn't look great. It has a lot of text on it and we want the background to be a dark brown colour, a gold border around it and the text in bold.
When we are adding content we create a content block and in this, we can add html, I have recently done a very basic course in html. I know normally the page will link to a CSS file which will provide the page style. But I also know you can add the <style> tag in and then add CSS directly into the HTML.
This is maybe a long shot but does anyone with any knowledge of template website know if it would work to add the css in this way just to change the background colour and give it a border? I presume I would need to use something like google dev tools to find out what the section names are to identify them in the CSS? According to dev tools the section I want to modify looks like this.
<div id="content">
<div class="cs-content-row">
Thanks
If you have very limited control, e.g. you can't add a <style> tag to the <head> or use a custom stylesheet, you can also resort to using inline style, and style individual elements using the style attribute.
See example of use;
<div style="background:brown; border:1px solid yellow; color:white; font-weight:bold; padding:30px;">Your text here</div>
The pros are it overrides the default styling easily, but the downside is you have to re-write code for every element you want to custom style, and if you changed your mind about the colour, you'll have to edit every instance it was used..
You mean normal css into html like this?
<html lang="en">
<head>
<style>
body{
background:red;
}
#content{
width:200px;
height:200px;
background:blue;
}
.cs-content-row{
width:100px;
height:100px;
background:green;
}
</style>
</head>
<body>
<div id="content">
<div class="cs-content-row">
</body>
</html>
You can use the style tag but you have to add it between the <head> tags of your page.
If your admin panel allows you to update that part of HTML you can do something like that :
According to your HTML description
<head>
<style>
#content{
/* css targeting the div with id attribute equals to 'content' */
}
.cs-content-row{
/* css targeting the div with class attribute equals to 'cs-content-row' */
}
</style>
</head>
I haven't done HTML and CSS for a while so I may be forgetting something, but for some reason a "style" tag with the "text-align" property set isn't working even in the simplest context. I'm about to show you the whole, entire file that I have but my problem is only in the two comments I have. Don't worry about the other stuff; it's for a little passion project I'm working on.
So here is the whole file. I have a lot of stuff in it that isn't relevant nor important; just focus on the code in the two comments.
<!doctype html>
<html>
<head>
<meta charset="utf-8"/>
<title>JSON Generator</title>
<link rel="stylesheet" href="web_mod.css"></link>
</head>
<body bgColor="#E3E3E3">
<!--Start here-->
<span style="text-align: center">Coded by AnnualMelons</span><br>
<!--Finish here-->
<span style="color: red; background-color: #2CE65A">Use this generator to generate the code required to create a JSON message.<br>
Fill in the blanks to generate the code. The generator will guide you through it as you go along. Have fun!</span>
<script>
</script>
</body>
</html>
The "Coded by AnnualMelons" part is supposed to be in the center but it's not. At least for me it's not.
I know that the other part of the file isn't relevant but I figured I might as well show you as it may be an external problem.
I'm sure I'm just making a silly mistake because I haven't done this for a while, but it's not working... so yeah. I'm using Firefox as my web browser in case that helps.
Thanks!
The <span> Element is, by default, an "inline" element. Meaning unlike block level elements (<div> <h1> <p> etc.) the span only takes up as much horizontal space as its content.
text-align: center IS working, but you're applying it to an element that doesn't have a width greater than its content (as all block elements do).
I recommend either changing the span to a <p> element, or specifying the display: block property on your span.
Here's a JSfiddle to demonstrate that both a <span> with display: block; text-align: center and a <p> with text-align: center; achieve the same effect.
Hope that helps!
Use a p or div rather than a span. Text is an inline element and so is a span. For text-align to work, it must be used on a block level element (p, div, etc.) to center the inline content.
example:
<div style="text-align: center">Coded by AnnualMelons</div><br>
Use this in style
margin-left: 50%;
example-
<span style="margin-left: 45%;">Centered Text</span>
.span {
text-align: center;
width: -webkit-fill-available;
}
This Worked for me and the text inside my span tag is now aligned to the center.
I am new to web-designing styles and css. I read that usage of tables for layout is a bad practice. Hence I tried to create this layout using <br\> , div and float.
Problem :
Once, <br\> is applied, I can't render the upper part, (similar to once \n is printed in console, we cant go to the upper line).
So, could any one provide an alternative way of designing the page, without using <table> and <br> tags.
Looks like a perfect example usage of a grid system.
Without using a grid system, you can just use float: left for each of the div and it should be OK.
Here is simple example for doing so,
<!DOCTYPE HTML>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title>StackOverFlow</title>
<style type="text/css">
.content{
width:150px;
height:100px;
border:1px solid blue;
}
.content .text{
display:block;
border:1px solid red;
}
</style>
</head>
<body>
<div class="content">
<div class="text">
text here
</div>
<div class="text">
another text here
</div>
<div class="text">
yet another text here
</div>
</div>
</body>
</html>
Code Explanation
What i did is wrap text div inside content parent div and assign fixed width and height to parent div.
Now for child div i just used display:block and see the result. You do not need to use <br/> display:block; will do it for you.
Now what is the meaning of display:block; so it just tell browser to allow that particular DOM to take whole width of the parent div.
By adding css to DIV's you can get some great layouts (i.e the three column style you're looking for here) , try this aticle to get you started:

Below is an exceedingly simple HTML page.
1) I would like to add a menu across the top, which means that the position of that edit box may have to change(?) or must it? Is the text box positioned relative to its enclosing div (which will follw the menu's div)?
2) I want to add more form elements, and position them precisely, with coords relative to the start of the form, just after the menu (I am generating the HTML programatically, if it helps to know that; for instance, I can add a fudge factor).
3) and after the last of those I want a submit button, which is always guaranteed to be at the bottom of the page, no matter how many input elements I add in the middle (so, perhaps wrap the form's controls in a div?
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
</head>
<body>
<form action="HTTP://localhost/b/submitted.php" method="post">
<div class="TEdit" id="TextEditBox1" style="position: absolute; top:56px; left: 72px; width: 121px; height: 21px;">
<input type="text" name="TextEditBox1">
</div>
<div class"submit_button" style="position:absolute; top:102px; left:132px;"><input type="submit" name="submitButton" value="Submit"></div>
</form>
</body>
</html>
For the most part, if you just put the page elements in the code in the order you wish to see them, flow of the page will lay them out as you've described.
For pixel perfect positioning, you can use absolute positioning as you have in there, but that's not that "best" way to do it.
I think the best thing for you to do would be to read up on CSS positioning over at w3schools if you want a good understanding of how to layout page elements.
When my browser renders the following test case, there's a gap below the image. From my understanding of CSS, the bottom of the blue box should touch the bottom of the red box. But that's not the case. Why?
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title>foo</title>
</head>
<body>
<div style="border: solid blue 2px; padding: 0px;">
<img alt='' style="border: solid red 2px; margin: 0px;" src="http://stackoverflow.com/Content/Img/stackoverflow-logo-250.png" />
</div>
</body>
</html>
Inline elements are vertically aligned to the baseline, not the very bottom of the containing box. This is because text needs a small amount of space underneath for descenders - the tails on letters like lowercase 'p'. So there is an imaginary line a short distance above the bottom, called the baseline, and inline elements are vertically aligned with it by default.
There's two ways of fixing this problem. You can either specify that the image should be vertically aligned to the bottom, or you can set it to be a block element, in which case it is no longer treated as a part of the text.
In addition to this, Internet Explorer has an HTML parsing bug that does not ignore trailing whitespace after a closing element, so removing this whitespace may be necessary if you are having problems with Internet Explorer compatibility.
Because the image is inline it sits on the baseline. Try
vertical-align: bottom;
Alternately, in IE sometimes if you have whitespace around an image you get that. So if you remove all the whitespace between the div and img tags, that may resolve it.
line-height: 0; on the parent DIV fixes this for me. Presumably, this means the default line-height is not 0.
display: block
in the image fixes it as well, but probably breaks it in other ways ;)
Remove the line break before the tag, so that it directly follows the tag with no blanks between it.
I don't know why, but for the Internet Explorer, this works.
font-size:0; on the parent DIV is another tricky way to fix it.
