how i can use two style on a div <div id="span,google"></span>
You can't assign two id's like that, but you can use two classes:
<div class="span google"></div>
Also, you can't start the element as a div and close it as a span as in your code. I'll write that off as a typo, tho.
.span { some-css }
.google { other-css }
You can do:
<div class="span google"></div>
where you should have .span and .google classes set in your stylesheet

For my two div elements below, how would I prevent the div element to skip to the next line?
<div class = "one">
One
<div class = "two">
Two
</div>
</div>
This results in:
One
Two
Question: How do I make it come in one row so it is as follows:
OneTwo
Simple...
.two {
display:inline-block;
}
And my fiddle http://jsfiddle.net/blackhawx/LfN9C/6/
The big issue is you need to wrap these so that you can display them correctly. I would move .two out of one. Then put class .one and .two inside .wrapper so that it can contain them. Then place display: inline-block on .wrapper div. See my example.
HTML
<div class="wrapper">
<div class = "one">
One
</div>
<div class = "two">
Two
</div>
</div>
CSS
.wrapper div{
display: inline-block;
}
Change the second div to a span:
<span class = "two">
Two
</span>
Two reasons:
It's doesn't add any extra CSS
It's more "semantic" to have a span contained inside of a div (rather than two divs hacked to fit into one another)
Hope this helps!
Here's a link to illustrate: http://jsfiddle.net/4HxhV/
I have a website and I should make certain divs transparent. I don't want to duplicate my divs with a transparent tag. I want to archieve something like this.
.wrapper { --div properties-- }
.transparent { --transparency properties --}
I want to set class attributes like this.
<div class="wrapper . transparent"></div>
So this div would get all the properties from wrapper style, then apply a transparent background.
Use class selectors instead of ID selectors:
.wrapper { --div properties-- }
.transparent { --transparency properties --}
And separate your class names by a single space in your HTML markup:
<div class="wrapper transparent"></div>
I saw this selector in Twitter Bootstrap:
.show-grid [class*="span"] {
background-color: #eee;
text-align: center;
border-radius: 3px;
min-height: 30px;
line-height: 30px;
}
Does anyone know what this technique is called and what it does?
It's an attribute wildcard selector. In the sample you've given, it looks for any child element under .show-grid that has a class that CONTAINS span.
So would select the <strong> element in this example:
<div class="show-grid">
<strong class="span6">Blah blah</strong>
</div>
You can also do searches for 'begins with...'
div[class^="something"] { }
which would work on something like this:-
<div class="something-else-class"></div>
and 'ends with...'
div[class$="something"] { }
which would work on
<div class="you-are-something"></div>

.show-grid [class*="span"]
It's a CSS selector that selects all elements with the class show-grid that has a child element whose class contains the name span.
The Following:
.show-grid [class*="span"] {
means that all child elements of '.show-grid' with a class that CONTAINS the word 'span' in it will acquire those CSS properties.
<div class="show-grid">
<div class="span">.span</div>
<div class="span6">span6</div>
<div class="attention-span">attention</div>
<div class="spanish">spanish</div>
<div class="mariospan">mariospan</div>
<div class="espanol">espanol</div>
<div>
<div class="span">.span</div>
</div>
<p class="span">span</p>
<span class="span">I do GET HIT</span>
<span>I DO NOT GET HIT since I need a class of 'span'</span>
</div>
<div class="span">I DO NOT GET HIT since I'm outside of .show-grid</span>
All of the elements get hit except for the <span> by itself.
In Regards to Bootstrap:
span6 : this was Bootstrap 2's scaffolding technique which divided a section into a horizontal grid, based on parts of 12. Thus span6 would have a width of 50%.
In the current day implementation of Bootstrap (v.3 and v.4), you now use the .col-* classes (e.g. col-sm-6), which also specifies a media breakpoint to handle responsiveness when the window shrinks below a certain size. Check Bootstrap 4.1 and Bootstrap 3.3.7 for more documentation. I would recommend going with a later Bootstrap nowadays
It selects all elements where the class name contains the string "span" somewhere. There's also ^= for the beginning of a string, and $= for the end of a string. Here's a good reference for some CSS selectors.
I'm only familiar with the bootstrap classes spanX where X is an integer, but if there were other selectors that ended in span, it would also fall under these rules.
It just helps to apply blanket CSS rules.
In my case I'm unable to apply background color for class due to dynamic change of class name with numbers
Ex:
Issue:
body .ForwardRef-root-198 .aura-ag-grid .ag-row:hover, body .ForwardRef-root-198 .ag-details-grid .ag-row:hover {
background-color: #2196f35c !important;
}
Solution:
body div[class*="ForwardRef-root-"] .aura-ag-grid .ag-row:hover, body div[class*="ForwardRef-root-"] .ag-details-grid .ag-row:hover {
background-color: #2196f35c !important;
}

In the html fragment below, I want the "main" div to have a background image only if "menu" div is not present in the markup. Is this possible?
<div class="header">
<div class="siteTitle">site title</div>
<div class="tagline">site tagline</div>
<div class='menu'></div>
</div>
<div class="main"></div>
http://www.w3.org/TR/css3-selectors/
E + F Matches any F element immediately preceded by a sibling element E.
E:not(s) an E element that does not match simple selector s
edit :not uses a simple selector, so unfortunately you can't use it to filter by properties of children, only attributes of the element.
A simple selector is either a type selector, universal selector, attribute selector, class selector, ID selector, or pseudo-class.
You could however put a .empty class on the menu and still use it.
.header .menu:not(.empty) + .main {
background:pink;
}
This solution is the best of both worlds, javascript but using css as per normal.
javascript:
if ($('.menu').length == 0){
$('body').addClass('no_menu');
}
css :
body.no_menu .main{
background:pink;
}
The only pure css solution i see is only possible if you rearrange your html like so:
<div class="header">
<div class="siteTitle">site title</div>
<div class="tagline">site tagline</div>
</div>
<div class="menu"></div>
<div class="main"></div>
then you can use this css to only apply a property):
.menu { background: none }
.menu ~ .main{ background: url() } /* or .menu + .main if they are guaranteed to be adjacent to each other on the code */
in this example, you can see it at work: http://jsfiddle.net/tYhxr/
(test it by deleting the menu div and running it again)
check Keyo's asnwer for a link about how selectors work.
If you can't change the html, the javascript is the way to go.
I hope this helps.
You could add a second class to your main <div> that only serves to add the background you want. Then when you create the markup, you just add the second class specifier to the <div> if you need it, or omit it if you don't.
div.main {
//main stuff
}
div.mainbg {
background: *background-specifications*;
}
When your menu div is present, you use this:
<div class="main mainbg">
And when it's missing, you stick with:
<div class="main">
I have something like:
<div id="content>
<h1>Welcome to Motor City Deli!</h1>
<div style=" font-size: 1.2em; font-weight: bolder;">Sep 19, 2010</div>
<div > ... </div>
What is the css selector for the second div (1st div within the "content" div) such that I can set the font color of the date within that div?
The MOST CORRECT answer to your question is...
#content > div:first-of-type { /* css */ }
This will apply the CSS to the first div that is a direct child of #content (which may or may not be the first child element of #content)
Another option:
#content > div:nth-of-type(1) { /* css */ }
You want
#content div:first-child {
/*css*/
}
If we can assume that the H1 is always going to be there, then
div h1+div {...}
but don't be afraid to specify the id of the content div:
#content h1+div {...}
That's about as good as you can get cross-browser right now without resorting to a JavaScript library like jQuery. Using h1+div ensures that only the first div after the H1 gets the style. There are alternatives, but they rely on CSS3 selectors, and thus won't work on most IE installs.
The closest thing to what you're looking for is the :first-child pseudoclass; unfortunately this will not work in your case because you have an <h1> before the <div>s. What I would suggest is that you either add a class to the <div>, like <div class="first"> and then style it that way, or use jQuery if you really can't add a class:
$('#content > div.first')
