i have got problem with this code :
my code
The problem is here:
.caption::before,
.caption::after {
z-index: -1;
}
#obsah {
position:relative;
background-color:red;
//z-index: 0;
}
(i think) .. I need the div#obsah under caption.
Any idea to solve this problem? ;) I am novice. Thank you.
edit:
IDEAL RESULT
when you hover the image, it shows a text (cause image is move to right and overflow is hidden)
But my text is under the red background of div#obsah..
I remove overflow:hidden to see better where is problem. (but the codes are identical)
I have finally found a solution for this. You need to go to
#obsah {
position:relative;
display:block;
padding-bottom:5px;
margin-left:auto;
margin-right:auto;
margin-bottom:30px;
background-color:red;
width:75%;
}
and do the following changes:
change position: relative; to position: absolute;
add z-index: -2;
Please see a working example here:

I wrote a Google Chrome extension, which popups a dialog with an autocomplete field and it's own style, but there are some sites where my CSS gets totally broken, which doesn't look very nice.
I know about isolating styles with iFrames, but in Google Chrome extension there is no way to isolate my HTML and CSS in this way. Another method is to wrap all my stuff into a separated div with it's own id and relative styles for that id, and I do so, but it seems that it doesn't work on some sites with "hard" tags style overloading or "!important" directives in the CSS code.
So, I want to know is there any way to really isolate my styles in z convenient way or it's my bad carma to overload every little CSS property to fix one or another style issue for each site?
By the way: I set up my manifest to load all the things at the "document_end", but I see it's not being applied to the stylesheets which is every time loaded whenever the DOM is ready.
At the time of asking the question, your only option was to either use iframes, or stylesheets with a very high specificity and explicitly set all properties that might affect styles. The last method is very cumbersome, because there will always be some property that is overlooked by you. Consequently, the only usable method for isolating stylesheets was to use iframes.
The solution to this problem -isolation of styles without iframes- is Shadow DOM (since Chrome 25). You can find a tutorial at HTML5 Rocks. For a real-world Chrome extension that uses Shadow DOM to isolate styles, see Display #Anchors (source code here).
As I've recently gone through the gauntlet of this issue, I want to share some information I think is valuable.
First, Rob W's answer is correct. Shadow DOM is the correct solution to this problem. However, in my case not only did I need CSS isolation, I also needed JavaScript events. For example, what happens if the user clicks a button that lives within the isolated HTML? This gets really ugly with just Shadow DOM, but we have another Web Components technology, Custom Elements, to the rescue. Except that as of this writing there is a bug in chrome that prevents custom element in chrome extensions. See my questions here and here and the bug here.
So where does that leave us? I believe the best solution today is IFrames, which is what I went with. The article shahalpk linked is great but it only describes part of the process. Here's how I did it:
First, create an html file and js file for your isolated widget. Everything inside these files will run in an isolated environment in an iframe. Be sure to source your js file from the html file.
//iframe.js
var button = document.querySelector('.my-button');
button.addEventListener('click', function() {
// do useful things
});
//iframe.html
<style>
/* css */
</style>
<button class='my-button'>Hi there</button>
<script src='iframe.js'></script>
Next, inside your content script create an iframe element in javascript. You need to do it in javascript because you have to use chrome.extension.getURL in order to grab your iframe html file:
var iframe = document.createElement('iframe');
iframe.src = chrome.extension.getURL("iframe.html");
document.body.appendChild(iframe);
And that's it.
One thing to keep in mind: If you need to communicated between the iframe and the rest of the content script, you need to chrome.runtime.sendMessage() to the background page, and then chrome.tabs.sendMessage from the background page back to the tab. They can't communicate directly.
EDIT: I wrote a blog post detailing everything I learned through my process, including a complete example chrome extension and lots of links to different information:

In case my blog goes down, here's the sources to the original post:
Blog post
Example source
Either use all
.some-selector {
all: initial;
}
.some-selector * {
all: unset;
}
or use Shadow DOM
Library
function Widget(nodeName, appendTo){
this.outer = document.createElement(nodeName || 'DIV');
this.outer.className = 'extension-widget-' + chrome.runtime.id;
this.inner = this.outer.createShadowRoot();
(appendTo || document.body).appendChild(this.outer);
}
Widget.prototype.show = function(){
this.outer.style.display = 'block';
return this;
};
Widget.prototype.hide = function(){
this.outer.style.display = 'none';
return this;
};
Usage
var myWidget = new Widget();
myWidget.inner.innerHTML = '<h1>myWidget</h1>';
You can access the widget contents via myWidget.inner and the outer via myWidget.outer.

I recently created Boundary, a CSS+JS library to solve problems just like this. Boundary creates elements that are completely separate from the existing webpage's CSS.
Take creating a dialog for example. After installing Boundary, you can do this in your content script
var dialog = Boundary.createBox("yourDialogID", "yourDialogClassName");
Boundary.loadBoxCSS("#yourDialogID", "style-for-elems-in-dialog.css");
Boundary.appendToBox(
"#yourDialogID",
"<button id='submit_button'>submit</button>"
);
Boundary.find("#submit_button").click(function() {
// some js after button is clicked.
});
Elements within #yourDialogID will not be affected by the existing webpage. And find() function returns a regular jQuery DOM element so you can do whatever you want with it.
Hope this helps. Please let me know if you have any question.

Use iframes. It's a workaround, but works fine.
Maxime has written an article on it.
I am unsing the application layout in an application where there is no footer. Is there a way to get the lotusColLeft (or/and lotusColRight) to be the same length as the lotusContent div? The users are complaining a bit on the fact that the left menu's background color doesn't go all the way to the bottom of the page.
You can use Firebug or some other CS debugger to see the CSS for the left pane and the content pane and see if you can tweak the CSS (maybe try 100% for the height).
You may end up having to get the height of the content div and then set the left div to the same height in CSJS onClientLoad. You will also have to use the same code in a window resize event in case the user changes the browser window size.

OK, here is how I finally made this happen: I used a background image. Not ideal, I agree, but less problemeatic than the original solution (at the bottom of this answer):
.lotusContent {
background: url(leftColBkgd.png) repeat-y;
}
.lotusColLeft {
background-color: grey;
position: absolute;
z-index: 10;
}
.lotusMain .lotusContent {
padding-left: 230px;
}
Original solution:
.lotusColLeft {
background-color: grey;
min-height:2048px;
position: absolute;
z-index: 10;
}
.lotusMain .lotusContent {
padding-left: 230px;
}
I have this in my css:
#media screen and (max-width:1200px) {
#cssmenu {
background:url(/public/system/assets/img/profile.png) no-repeat , url(/public/system/assets/img/bgprofile.jpg) repeat-x;
width: 100%;
}
}
#media screen and (max-width:970px) {
#cssmenu {
background:url(/public/system/assets/img/profile.png) no-repeat , url(/public/system/assets/img/bgprofile.jpg) repeat-x;
width: 150px;
}
}
I get an error with csslint task:
Background image '/public/system/assets/img/bgprofile.jpg' was used multiple times, first declared at line 753, col 3. Every background-image should be unique. Use a common class for e.g. sprites. (duplicate-background-images)
Is there a way to declare these images so that I don't get this error?
Edit (another case):
.linkmycars
{
background:url('/public/system/assets/img/sub.png') no-repeat right 20px, url('/public/system/assets/img/bglinkcars.png') repeat-x #ececec;
}
.addcars
{
background:url('/public/system/assets/img/add.png') no-repeat right 17px, url('/public/system/assets/img/bglinkcars.png') repeat-x #ececec;
}
And I get this error: [L651:C1]
Background image '/public/system/assets/img/bglinkcars.png' was used multiple times, first declared at line 628, col 1. Every background-image should be unique. Use a common class for e.g. sprites. (d
uplicate-background-images)
One of your rules here seems totally redundant. The rule under max-width: 970px is already true when under max-width: 1200px.
To recap, change it to:
#media screen and (max-width:1200px) {
#cssmenu {
background:url(/public/system/assets/img/profile.png) no-repeat , url(/public/system/assets/img/bgprofile.jpg) repeat-x;
width: 100%;
}
}
#media screen and (max-width:970px) {
#cssmenu {
width: 150px;
}
}
As for your edited question, you face a couple of options. Because you have different images, you can't combine the two rules there.
Option one: sprite sub.png and add.png together, then use background position to move them into position/out of sight. This would only work in some cases, and it's a bit of a mess, depending on the layout. I made kind of a lazy example, just so you understand what I mean. You will probably have to create a sprite with a lot of transparent space between sub.png and add.png: jsfiddle
Option two: easier but less semantic. Instead of using multiple backgrounds, use multiple elements. jsfiddle and example:
html:
<div class="tiles"><div class="linkmycars"></div></div>
<div class="tiles"><div class="addcars"></div></div>
css:
.tiles {
background: url(/public/system/assets/img/bgprofile.jpg) repeat-x;
}
.linkmycars, .addcars {
width: 100%;
height: 100%;
}
.linkmycars {
background: url('/public/system/assets/img/sub.png') no-repeat right 20px;
}
.addcars {
background: url('/public/system/assets/img/add.png') no-repeat right 17px;
}
Third option: don't worry too much about csslint. It's there to help you, not make you jump through hoops. Your code will work great either way.
Hope it helped.
I'm trying to change places of ofbiz components like application bar and main container places, I know that maybe can be changes from /common/widget/CommonScreens.xml or something like that (such as another xml file), I tired without luck to find what the file responsible to render "app-navigation" and just I lost my way.
So I hope find my answer here, I want to change layout,
The default interface is look like this:
What I want is (I made this using firebug) :
How I can do that?? or in another word from where I can start to do that?
leave the CSS and HTML side for me, I just want the point to start with, to edit theme layout to be like what I explained in previous screenshot.
Sorry If I cant give you what I want clearly my English didn't help me today :) but you can ask me in comment about anything if not clear yet.
take a look at the other themes in OFBiz. The bizness_time theme is already using a similar layout.
Cheers
I solved my issue, there was a little mistake from my side, and I did some modification;
In CSS file:
#app-navigation {
...
/* border-top: 0.1em solid #3E5A71; */ /*Removed*/
...
width: 200px; /*Added*/
float: left; /*Added*/
}
...
#app-navigation ul li ul li {
...
/* float: left;
display: inline; */ /*Removed*/
...
}
/*Added*/
#container:after {
content: ".";
display: block;
clear: both;
visibility: hidden;
line-height: 0;
height: 0;
}
In templates :
At appbar.ftl , or appbarOpen.ftl :
<div id="container"> <!-- This is the Line that I Added -->
<#if userLogin?has_content>
...
And in footer.ftl :
</div> <!-- This is the Line that I Added -->
<div id="footer">
...
Simply :)
i'm trying to make up a different look and feel on my sharepoint site. I try to make my main content's width down to 960px under my form tag in sharepoitn designer. when I refresh the page at the first it renders the main content down to 960px but when the page fishished loading the main content stretches itself to the whole screen's width.
I found out that it's because of the onload script running in body tag. but I caanot remove this script because this work has side effects on page functionality.
the function is _spBodyOnLoadWrapper().
does anyone know this function ? or does anyone know how to come up with this problem ?
UPDATE #1:
My css code is as follows.. I added this class to the main Form on master page:
.mainContent
{
width: 960px;
height:100% !important;
min-height:100% !important;
padding-top: 10px;
margin-left: auto;
margin-right: auto;
direction:rtl;
}
UPDATE #2:
I use v4.master template.
I have taken the ribbon out of the form tag. it's directly after body tag. because I wanted the ribbon to be streched at the top. but when i add this line of code
<body onload="if (typeof(_spBodyOnLoadWrapper) != 'undefined') _spBodyOnLoadWrapper();">
the mainContent blows up. something at the header streches in the whole width and some panels at bottom remains 960px.
you got me interested so I recreated your issue. By default, the javascript will try to inline the width based on its calculations.
However, what you need is to set the class s4-notsetwidth on a wrapping container.
Here is what i did to fix your issue
Add this to the head
<style type="text/css">
#s4-bodyContainer {
width: 960px;
height:100% !important;
min-height:100% !important;
padding-top: 10px;
margin-left: auto;
margin-right: auto;
}
/* Aligns the Top Bars */
.ms-cui-ribbonTopBars {
width: 960px!important;
margin-left:auto;
margin-right:auto;
}
/* Turns off the border on the bottom of the tabs */
.ms-cui-ribbonTopBars > div {
border-bottom:1px solid transparent !important;
}
</style>
Then locate the s4-workspace (that's the immediate parent of #s4-bodyContainer and add class s4-nosetwidth. That should work for you.
Use these two references to achieve exactly what you want (not sure if you want ribbon aligned or not), Randy Drisgill post and Tom Wilson's post.
