pretty html highlighting using <span> - html

I'm highlighting text in a HTML document using <span> tags around the content to be highlighted. The span class has a background-color defined, and a border-radius is also set. This works well.
I'd like the highlight to extend a bit further beyond the normal extents of the <span> content. That is, a few pixels to the left of the span-start, and a few pixels to the right of the span-end. Ideally I'd do this without spacing apart the content itself.
Any good css tricks I can use to achieve this?

You can set a padding and a negative margin. For example:
span {
margin: -5px;
padding: 5px;
}
You can see a demo here.

margin: 10px 0px; ??
if this does not solve your issue can you elaborate on the problem ?

half page full width Styling CSS

I am currently working on this website: http://mdftanzania.com. I am using Wordpress and headway101. I want to have a full width green background color that applies to the begin part of the page: About Us and Services. I add a div class to the part of the page where the green background has to be. I tried to style the div class to a full width green background, this didn't work out and at the moment only a part is styled now (see the website: http://mdftanzania.com).
I understand that there is another solutions, that is creating a container or widget above the container for the content, where I place the first part of the page text in. The problem with this is that it is confusing for my client where to edit the text in the page. The simplicity of Wordpress goes basically away then. Because of that, I am looking for a solution with CSS styling, so the client is only dealing with the 's.
Does anybody has a solution for this?
Since you have predetermined a padding to the content block, it is obviously affecting all the child elements that are contained in it, including the div with green background, which means that you should either remove that padding and apply it only to specific elements, or apply this simple CSS workaround to your div:
{
margin: 0 -25px;
padding: 0 25px;
}
This makes it, in your words, "full width" and applies a padding to its content.
You have this rule set in your css:
.block-type-content {
padding-left: 25px;
padding-right: 25px;
padding-top: 120px;
}
So children of this container, even though they may have a width of 100%, have to obey this padding of their parent. That's why you don't get a full width green bar. You might try negative margin-left and right to expand your green bar:
.color {
margin: 0 -25px;
padding: 0 25px;
}
At least in Firefox/Mac, this solves your issue.

Remove unexplainable img margin/space (CSS)

I have some unexplainable image margin/Space below img when including images in my wordpress theme. You can see it here: http://www.wlanradios.net/logitech-squeezebox-radio/
See the Amazon logo image inside the content or scroll down and have a look in the "Ähnliche WLAN Radios" sidebar widget with the small thumbnails. The images seem to have a little margin-bottom / Space below it I can not get rid off. I discovered the html/css with firebug but don't get the it where this margins comes from. I in fact tried to
img {
margin:0!important;
padding:0!important;
border:0!important;
}
to overwrite every possible causes for the margin, with no success.
Where is the margin coming from and how to remove it?
Just put to those imgs :
display: block;
UPDATE:
Some explanations: img is an inline element, so it has to deal with white-space, line-height, etc., as all inline elements. I guess the space you're seeing is actually caused by the line-height. So another solution if you want to keep your img as inline elements is to set its parent line-height: 0;.
Have you tried: vertical-align: middle
I have Deeply inspected the Issue, its a bit of haystick needle kind of thing.
1) Amazon Image box - Issue is with the td tag which creates a all sides padding of 6.71667px , This is FORCEFULLY created by the td,th padding which is set to 0.5em
th, td {
border-spacing: 3px;
//Tweak this Padding of 0.5em and you should destroy Amazon Extra Space
padding: 0.5em;
border: 1px solid #CCC;
}
You should be able to find and edit from line 183 of the above css theme from wp-content/themes/ar2-2-b-2-fixed/styles.css
2) Coming to the second issue with WLAN Radios Pic , This image is pushed in due to the DIV tags Padding all set to 4px which is acting on the WLAN Radio pics.
Here are the Issue Pics:
Amazon Image Issue Solved Pic
Hope this Helps :)
Check for your line-height on the img elements, and set it to 1. You must have a line height > 1 on a parent element.
You can also change the display of those img to 'block' (to avoid line spacing).

3 inline-block divs with exactly 33% width not fitting in parent

This is a common problem but I can't figure out why it happens.
I have a parent div and inside that div I have 3 divs with width set to 33% (exactly, not 33.3%!) and display: inline-block.
In Chrome it works well, but in Mozilla and Opera it does not (I didn't test it in IE yet). I thought the problem might be in the algorithm browsers use to calculate pixel sizing from percentages. But when I checked the DOM metrics, I found that the parent's width is 864px and the child's is 285px (that's correct: 864 * .33 = 285.12). But why doesn't it fit in the parent? 285 * 3 = 855, that's 9px less than parent's width!
Oh, yes, padding, margin and border for all divs set to 0 and DOM metrics confirm that.
Whitespace in the HTML source code
In the HTML source code, When you have lines of text or images, or elements that are inline-block, if there is any whitespace between them (blank spaces, tabs, or new lines), a single blank space character will be added between them when the page is rendered. For example, in the following HTML, a blank space will appear between each of the four pieces of content:
one
two
<img src="three.png"/>
<span style="display: inline-block;">four<span>
This is very helpful for lines of text, and for small images or HTML elements that appear inside a line of text. But it becomes a problem when inline-block is used for layout purposes, rather than as way to add content inside a paragraph of text.
Removing the extra space
The safest, cross-browser way to avoid the extra 4px or so of space that's added between inline-block elements, is to remove any whitespace in the HTML source code between the HTML tags.
For instance, if you have a ul with 3 floated li tags:
<-- No space, tabs, or line breaks between </li> and <li> -->
<ul>
<li>...</li><li>...</li><li>...</li>
</ul>
Unfortunately, this hurts the maintainability of the website. Besides making the code unreadable, it severely compromises the separation of data and formatting.
If another programmer comes along later and decides to put each li tag on a separate line in the source code (unaware of why the tags were on the same line, or possibly running it through HTML Tidy and not even having a chance to notice any related HTML comments), suddenly the website has a formatting bug that may be difficult to identify.
Consider floating elements instead
The whitespace behavior strongly suggests that it may be inappropriate to use inline-block for general-layout purposes, to use it for anything other than adding content inside the flow of a paragraph of text.
Plus, in some cases inline-block content is very difficult to fully style and align, especially on older browsers.
Quick summary of other solutions
Put the close tag on the same line as the next open tag, with no white space between them.
Use HTML comments to fill all of the whitespace between the close tag and the next open tag (as #Arbel suggested).
Add a negative left margin to each element (usually -3px or -4px, based on the font-size). I don't recommend this particular approach.
Set the font-size for the container element to 0 or 0.01em. This doesn't work in Safari 5 (not sure about later versions), and it may interfere with Responsive Design websites, or any website that uses a font-size unit other than px.
Remove whitespace-only text nodes from the container using JavaScript or jQuery. This doesn't work in IE8 and earlier, as text nodes are not created in those browsers when there's only whitespace between elements, though space is still added between the elements.
Set letter-spacing and word-spacing for the container (as #PhillipWills suggested). Further info. This requires standardizing em sizes on the website, which may not be a reasonable option for all websites.
Add text-space-collapse: discard; to the container (previously called white-space-collapse). Unfortunately, this CSS3 style is not yet supported by any browsers, and the standard hasn't been fully defined.
If you don't want to mess up the HTML formatting e.g. having all the elements with inline-block written in one line for future readability and also get rid of the extra white space that is added between them, you can "comment" the white space.
For example in your code this will solve the problem, it will even work with 33.3% instead of 33%:
.parent {
width: 100%;
}
.child{
display: inline-block;
width: 33.3%;
}
/\
<div class="parent">
<div class="child">bla-bla1</div><!--
--><div class="child">bla-bla2</div><!--
--><div class="child">bla-bla3</div>
</div>
A space is added between the inner divs. There is some CSS voodoo to correct this problem:
div {
letter-spacing: -.31em;
word-spacing: -.43em;
}
div div {
letter-spacing: normal;
word-spacing: normal;
}
Of course, you'll probably prefer to use classes or something to differentiate between parent and children.
Add float:left;
.parent{
width: 100%
}
.child{
float:left;
display: inline-block;
width: 33%
}
http://jsfiddle.net/H6Whc/1/
Has anyone tried display: table? If that's not a good idea, why not? This works in all modern browsers and I tested it down to IE9.
.parent{
display: table;
width: 100%;
}
.containers {
box-sizing: border-box;
border: 1px solid #000;
height: 50px;
width: 33.3%;
display: table-cell;
}
This is a mentioned by a number of comments and by #Avin, but removing display: inline-block and replacing it with float: left works.
.parent{
width: 100%
}
.child{
float:left;
width: 33%
}
This is a common problem, but it can be sorted out very easily by assigning the display: table CSS property to the parent div.

Space under <img> tag

I have this annoying space under my picture for no reason.
I'm using www.getskeleton.com as the framework.
HTML code
<div class="four columns bottom">
<div class="box">
<img src="images/picture.png" title="" alt="">
</div>
</div>
CSS code
.box{
border: 1px solid #bfbfbf; /* ---- Border OUTSIDE*/
}
Although I'm sure this has since been resolved, I believe none of these answers are correct (or at least, the link from the "accepted" answer is dead).
The way to deal with this spacing issue (and why it isn't set in util libraries like normalize I'm not sure) is vertical alignment of the image. This'll solve it for HTML pages when using the HTML 5 doctype. Oddly, when using e.g., HTML 4.01 doctype, images will not exhibit this errant space below behaviour.
The fix:
img {
vertical-align: top;
}
I hope that helps someone who may have run into this problem.
Edit: Some extra info I noticed after writing this and subsequently researching why normalize doesn't set alignment on the img tag; the default alignment for images is vertical-align: baseline; - that's the behaviour which introduces the space underneath. Normalize's author believes this behaviour is consistent cross-browser, and so has decided not to 'normalize' this. I suppose that makes sense if you wanted text sitting next to an image to align properly with any subsequent lines of text. Some people also prefer to use vertical-align: middle as opposed to top to address this issue - so you can vary this as you wish.
However, regarding baseline alignment, in the case where I had an image that was so big that it was higher than the line-height, I'd probably be floating it or some other behaviour anyway... but there you go.
I've used the vertical-align stuff for a while now without any incident. But as always, do ensure you test for any repercussions for images no longer being aligned to the baseline.
Try this:
.box img {
display: block;
padding: 0px;
margin: 0px;
}
Try this: .box { font-size: 0; }
Your image need to be floated. Try this:
#yourimage{
float: left;}
As mentioned, more information would help a lot but i have no doubt that it is padding that is causing the border to go out of the image, reason put very simply being
margin pushes outside the element
padding pushes inside the element
as it were.
Fix then:
.box {
padding-bottom: 0px;
}
//to be sure that the image doesn't have any padding, even though OP said the .box img fix didn't help
.box img {
margin-bottom: 0px;
}
It's an age old quirk - the whitespace from your line formatting is causing the gap. Add
<br /> after the image.
Try this
.box{
display:flex
}

How do I keep a DIV from expanding to take up all available width?

In the following HTML, I'd like the frame around the image to be snug -- not to stretch out and take up all the available width in the parent container. I know there are a couple of ways to do this (including horrible things like manually setting its width to a particular number of pixels), but what is the right way?
Edit: One answer suggests I turn off "display:block" -- but this causes the rendering to look malformed in every browser I've tested it in. Is there a way to get a nice-looking rendering with "display:block" off?
Edit: If I add "float: left" to the pictureframe and "clear:both" to the P tag, it looks great. But I don't always want these frames floated to the left. Is there a more direct way to accomplish whatever "float" is doing?
.pictureframe {
display: block;
margin: 5px;
padding: 5px;
border: solid brown 2px;
background-color: #ffeecc;
}
#foo {
border: solid blue 2px;
float: left;
}
img {
display: block;
}
<div id="foo">
<span class="pictureframe">
<img alt=''
src="http://stackoverflow.com/favicon.ico" />
</span>
<p>
Why is the beige rectangle so wide?
</p>
</div>
The right way is to use:
.pictureframe {
display: inline-block;
}
Edit: Floating the element also produces the same effect, this is because floating elements use the same shrink-to-fit algorithm for determining the width.
The beige rectangle is so wide because you have display: block on the span, turning an inline element into a block element. A block element is supposed to take up all available width, an inline element does not. Try removing the display: block from the css.
Adding "float:left" to the span.pictureFrame selector fixes the problem as that's what "float:left" does :) Apart from everything else floating an element to the left will make it occupy only the space required by its contents. Any following block elements (the "p" for example) will float around the "floated" element. If you "clear" the float of the "p" it would follow the normal document flow thus going below span.pictureFrame. In fact you need "clear:left" as the element has been "float:left"-ed.
For a more formal explanation you can check the CSS spec although it is beyond most people's comprehension.
Yes
display:inline-block is your friend.
Also have a look at: display:-moz-inline-block and display:-moz-inline-box.
The only way I've been able to do picture frames reliably across browsers is to set the width dynamically. Here is an example using jQuery:
$(window).load(function(){
$('img').wrap('<div class="pictureFrame"></div>');
$('div.pictureFrame').each(function(i) {
$(this).width($('*:first', this).width());
});
});
This will work even if you don't know the image dimensions ahead of time, because it waits for the images to load (note we're using $(window).load rather than the more common $(document).ready) before adding the picture frame. It's a bit ugly, but it works.
Here is the pictureFrame CSS for this example:
.pictureFrame {
background-color:#FFFFFF;
border:1px solid #CCCCCC;
line-height:0;
padding:5px;
}
I'd love to see a reliable, cross-browser, CSS-only solution to this problem. This solution is something I came up with for a past project after much frustration trying to get it working with only CSS and HTML.
