Right now we have a web page with a bunch of link sections on one page. Each section has a header like so:
This header background is actually two images. The first is just a rectangle and the second has the slanted side on it. As I was looking at this solution, I was wondering if I could solve this with CSS instead of images. While I am not a CSS guru, I did look at a number of examples and was able to get something similar working. However, when I attempt to put text on top of the background, it ends up above the color instead of inside it. The CSS I have also has a fixed size, which is less than idea. I would rather specify a percentage of the available area and have it fill in the color.
Here is the code I've been working with:
<STYLE type="text/css">
.mini_banner
{
display:inline;
border-bottom:30px solid blue;
border-left:0px solid transparent;
border-right:30px solid transparent;
}
</STYLE>
I wanted to apply this to a cell in a table. I also don't want to break compatibility with modern browsers. My "customers" (mostly internal people) are going to be primarily on IE8 or later but I don't want to limit myself if I can help it.
So first, is this possible? Second, how would I accomplish this? And third, is there a way to make it relative in scale instead of fixed?
I would say that you'll have less headaches all the way around if you revert to using a single background image - in this case, a white image with the notch cut out (a PNG-24 with alpha transparency). Make it bigger than you think you need by about 200%, then do something like this:
.minibanner {
background: blue url(..images/notch.png) no-repeat middle right;
font-size: 1.5em;
}
The reason is that relying on border sizes may result in some whackiness across browsers, and it will definitely look weird if any element runs to two lines.
If you make the notch image 200-300% larger, but vertically align it in the middle of the background, and you do increase the font-size, the box will grow, but your white notch will grow right along with it.
UPDATE:
The only other way I can see pulling this off is to add a non-semantic element, such as a or something similar, after your text:
<div>
<p>Hello text</p>
<span></span>
</div>
Then in your CSS:
p {
background: blue;
color: white;
float: left;
padding: 0 20px;
height: 50px;
margin:0;
line-height: 50px;
}
span {
width: 0;
height: 0;
border-top: 50px solid transparent;
border-bottom: 0px solid transparent;
display: inline-block;
border-left: 50px solid blue;
}
See this JSFiddle.
The shape is based on this tutorial on CSS triangles. Now, I've only tried this on a webkit based browser, and it works. You will have to adjust the heights every time you want to change font size, so that is a drawback.
I made it work without an extra span: jsFiddle
.mini_banner
{
width:18em; height:1.5em;
color:white; font-weight:bold; padding-left:0.5em;
margin-bottom:.5em;
}
.mini_banner:before {
display:inline-block; content:''; overflow:hidden;
width:17em; height:0;
margin-bottom:-1.5em; margin-left:-.5em;
border-bottom:1.5em solid blue;
border-right:1.5em solid transparent;
}
Tested in FF, Safari, Opera and IE. (Works in IE8, but not in IE7)

How do CSS triangles work?
(23 answers)
Closed 7 years ago.
I recently worked on creating an element with some text inside it, but it has to be flag based shaped. I googled and found below nice css to achieve it. They basically created small triangles out of div(pointing to left/right/top/bottom) using css and attaching it with adjacent div.
However,I did not find any answers with the logic mentioned thus making me little confused about the triangle creation out of div using CSS.
I wanted to know how that css works, specifically for arrow-left class used below.
HTML:
<div class='element'>
<p>OFFER</p>
<div class="arrow-left"></div>
</div>
CSS:
.element{
background-color:#E47911;
display:inline-block;
position:relative;
padding:2px 15px 2px 10px;
color:white;
line-height:18px;
}
p{
font-size:10px;
margin:0;
}
.arrow-left {
width: 0;
height: 0;
border-top: 11px solid transparent;
border-bottom: 11px solid transparent;
border-right: 11px solid white;
display:inline-block;
position:absolute;
top:0px;
right:0px;
}
Here's the codepen link: http://codepen.io/anon/pen/JGvBpN
Any pointers is much appreciated! Thanks.
It doesn't create a triangle so much as it appears to given how border intersections are rendered at an angle.
.arrow-left {
width: 0; /* unnecessary, but does override any unexpected width */
height: 0; /* unnecessary, but does override any unexpected height */
/* These set up the intersecting borders, set each one to a different color to see the borders forming the "triangle" e.g. red, green, blue */
border-top: 11px solid transparent;
border-bottom: 11px solid transparent;
border-right: 11px solid white;
display:inline-block; /* unnecessary, you're taking the elemtn out of the document flow when you absolute potiion it and the div id a block level element anyway, but to correctly have a border you'll need this so it's a decent safeguard */
/* this takes the element out of the document flow and positions it absolutely within the nearest positioning parent, in this case, the relatively positioned parent */
position:absolute;
/* this moves it to the top right edges of the positioning parent*/
top:0px;
right:0px;
}
Here'es an illustration of the box in chrome's dev tools, pulled out of position to make the effect of what's going on made more obvious:
And here it is with positioning restored:
Note that the part you think is transparent is actually opaque so this isn't masking any part of the orange checkout block; it would be obvious that you drew a white part there if the background of the underlying page were not also white.
For what it's worth, it may be worth looking into using an image or SVG and CSS masking to actually "cut" part of the button out, but you'll need to check the user agent support for your needs or try some work arounds.
Alright, of course I understand why this is happening, I'm just hoping there's some creative solution. Let's say I have this element:
.element {
padding:0 1px;
}
.element:hover {
font-weight:bold;
}
It's crucial that the padding be in place for visual consistency, but is there some magical way I'm not aware of to lock the element's width down before engaging in the hover behavior?
No JavaScript allowed, unfortunately.

More Info
The client is extremely specific about what they want on certain parts of the site, and the nav is one of them, much to my frustration. They insist on hover being black text on a dark shade of red used in their logo, and they want the buttons to be centered. Since different browsers render text differently, the only way to create a consistent look is to use padding to create the width. Unfortunately, with normal font weight the black is very difficult to read.
You can use this approach:
#hoverEle {
width: 100px;
}
#hoverEle {
display:inline-block;
border:1px solid black;
padding:3px;
text-align: center;
}
#hoverEle:hover {
font-weight:bold;
}

Cons is fixed width.
By the way, I think it is bad idea to focus buttons like this. More beautifull for user will be simple color change (e.g. #ccc) and, probably, transition effect. I think it is much more better.
Try this fiddle: http://jsfiddle.net/M9V3Q/9/
I think it is much more beautifull even in this variant :)
Try something like:
.element {
padding: 0 1px;
border: 2px solid transparent;
}
.element:hover {
font-weight: bold;
border: none;
}

Could always try CSS3 box-sizing. It cuts into the elements width etc for padding, border..., and so prevents the element from expanding outside its set width.
Need to prefix -moz- or -webkit- for Firefox and safari.
I read once how to create cross-browser rounded buttons with shadow using images, I lost my bookmarks unfortunately that's why I ask does anybody remember the technique.
There is left side picture i.e
And then very wide body image which ends up with right curved border/shadow like this :
So at the end you end up with one button which can be used with multiple sizes? I was googling this, but it seems noways everyone use css without images.
Does anybody knows how this technique is called or can refer me to the link? or give me code example, I'd appreciate any of those
When using an image for the start and one for end of the button, these technique is called "sliding doors" and there are myriads of search results with any search engine…
For an introduction read the A List Apart article: http://www.alistapart.com/articles/slidingdoors
But as Neurofluxation asked you in the comment above: Why the hell would you do that years after we have multiple other methods of styling a button in CSS? The A List Apart article for example is from 2003 - which is an age in Internet terms.
This technique is a variation of the "Sliding Doors" technique:
http://www.alistapart.com/articles/slidingdoors/
http://css-tricks.com/snippets/css/perfect-css-sprite-sliding-doors-button/
http://azadcreative.com/2009/03/bulletproof-css-sliding-doors/
Basically you use markup like this:
<button><span>Text</span></button>
Then style the span with the edge image to the side, overlapping the main background image of the parent element. Something like this:
button {
background:url(main-image.png) top right no-repeat;
border:0;
padding:0;
width:80px; /* with only 1 "door", you might need to set a width */
/* other resets may be necessary */
}
span {
background:url(left-door.png) left top no-repeat;
}
button, span {
height:37px; /* height of your sprite */
display:block;
}
Demo: http://jsfiddle.net/Kqs3m/
Your results may vary depending on your sprites and the natural width of the content.
Here's the technique which I think you are looking for (using the same images you attached):
HTML:
<a href="#" class="button">
<span>Small</span>
</a>
<a href="#" class="button">
<span>Large button</span>
</a>
CSS:
.button {
background: url('http://i.stack.imgur.com/htUHL.png') no-repeat left top;
padding-left: 9px;
height: 37px;
display: inline-block;
text-decoration: none;
color: #555;
text-shadow: 0 1px 1px #FFF;
font-family: sans-serif;
font-size: 0.8em;
}
.button span {
background: url('http://i.stack.imgur.com/ID6nO.png') no-repeat right top;
display: inline-block;
height: 37px;
padding: 5px 12px 5px 3px;
}
.button:hover span {
color: #333;
}

Using CSS properties instead of images can make your applications faster.
In this case you could just use: Border-Radius, Box-Shadow combined with a gradient background.
Here you can find a good Gradient Editor:

I'm writing a page that looks code wise like
<div class="green">
<span class="orange">s1</span>
<span class="orange">s2</span>
</div>
but that should be formated via CSS like:
The surrounding black frame shows the full page in the browser. (Think of <body></body>)
The red frame is a fixed width and fixed hight basically empty space that should be added by the CSS .green:before (I'm using it's ability to format it's borders for a visual effect)
The green frame shows the real content that should be as wide as necessary to contain both <span> in one line
The blue frame should be created by the CSS .green:after, has a fixed height and should take up all the space till the right border of the page - i.e. it must have a variable width.
Required browsers are the modern ones (Firefox, Chrome, Safari, Opera) in recent versions. No need to take care of IE. Mobile browsers would be great, though.
How can I achieve that? (All my attempts failed sooner or later...)
A jsFiddle with this example code is at http://jsfiddle.net/X2MDG/
I'm afraid that there is no way to satisfy all your constraints. The main things that don't seem to have a CSS solution are:
Controlling the width of just the green bit can't be done without affecting the width of the red :before and blue :after content. As you mention in the comments to the question, using a different DOM structure is not an option.
The blue (:after) content should take up all space not needed by the green (main) content.
The fixed height of red/blue may require some clearing on the elements below the entire div.
So, as far as I could tell, the question as you asked it doesn't have a 100% satisfying answer. Either way, here's the code I came up with researching this problem, perhaps it can help you or others stumbling on this question. See either this jsfiddle or the code below:
<div id="page">
<div class="green">
<span>Orange 1.</span>
<span>Orange 2. Which can be really wide.</span>
</div>
<p style="clear: both;">Black is the page. Clearing is
needed because the red and blue boxes are not in the
flow but do have quite some height.</p>
</div>
CSS:
div#page {
border: 2px solid black;
width: 80%;
padding: 2px;
}
div.green:before {
content: 'red / before';
border: 2px solid red;
float: left;
display: inline-block;
width: 140px;
height: 200px;
}
div.green {
border: 2px solid green;
}
div.green:after {
content: 'blue / after';
border: 2px solid blue;
display: inline-block;
float: right;
height: 60px;
}
div.green span {
border: 2px solid orange;
}
I'm looking for a way to do something which in my opinion should be super simple, but I couldn't figure it out...
I want a graphical element on my web page which is exactly 1 pixel high, 100% wide and has a certain color, let's say red. It should look exactly the same in all browser and should preferably not break the semantics too much.
I don't want to use any images for this and I don't want to use more than one HTML element. Of course, I will not use JavaScript.
I tried the old classic which probably many of you know:
<div class="hr"></div>
<style ...>
.hr {
height: 1px;
background: red;
width: 100%;
font-size: 1px; /* IE 6 */
}
</style>
The problem with the above solution is that IE6 will render this as two or three pixels high, to fit the non-existing contents of the div.
Any ideas?
just do
.hr {
height: 0px;
margin: 0px;
border-bottom: 1px solid #FF0000;
font-size: 1px;
}
I went through the same thing when I was new to CSS.
adding an overflow: hidden; style should fix it also.
I don't have IE6 handy to test, but an actual HR tag can work in modern browsers. Took me a couple of tries to realise you set the background color not the border color:
hr { width:75%; height:1px; background-color:#ebebeb; border:none; margin:1.5em auto; }
(adjust to suit)
I don't have IE6 to test this, but I remember it had to do something with the line height. Have you tried this?
line-height: 1px;
