Hope someone can help me, I have an index.php setup and in the head I have a sideshow script set and this runs on all pages, and then in the portfolio.html (loads inside the index.php file when that page is called up) I have a gallery script.
My problem is when I click on a gallery image it opens up but behind this "header gallery" ...
image of what the problem is:
#pjumble is right about wanting to change the z-index. The problem you're having is probably related to the CSS Selectors priority.
When defining a CSS format you can write the selector statement in 3 basic ways and mix and match these as you please for advance selector definitions. Here are the 3 basic ways,
1.
Class's Looks something like this.
.class1
{
color:blue;
font-size: 24px;
background-color:red;
}
this is the Lowest priority
2.
ID's Looks something like this.
#id1
{
color:yellow;
font-size: 12px;
}
This is medium priority
3.
Tag's look something like this.
Div
{
color:green;
}
This one gets highest priority. This always seems counter intuitive to me. If I define and ID level format you think that would have priority over the one for that Tag name but it doesn't.
Here's and example of what I'm talking about.
So for an element like this
<Div id="id1" class="class1">
Text
</div>
The "Text" here is going to have a red background because "class1" is the only definition with a background-color.
But both "id1" and "class1" have definitions for font-size so the class definition is ignored and the id one is used making "Text" 12px.
Then all three definitions have "color" defined and the winner is "Div" making "Text" green.
so when you write your set up like this,
#lightbox a z-index of 100, .gallerylayer has a z-index of 1000
you have the right idea but your definition for ".gallerylayer" is a class and if the tag or id of that section of code has z-index defined, your class definition of z-index = 1000; will be ignored.
Just to make sure the definitions not ignored I'd give the tag that has class='gallerylayer' in it and add a id='somethingUnique' attribute and use that to define the z-index rule.
But the best way to check this is to use Firefox with the Firebug add-on and use the element selecting tool to see what styles are being apply and which are begin ignored on your page.
For more on selectors try looking here it should give you all the documentation you'll need.
hope this helps.

Okay so I've been making website for my mom's business and stumbled onto an interesting thing I can't really find difference on, right now, since website is still in early development.(tried googling but no help)
So basically my question is:
What is the difference in css(and html) between;
container a:hover;
and
container:hover;
I mean it shouldn't be any different. In both cases, as long as there is only <a></a> type used like here, it will apply to everything:
#name of the button
The thing is here:
.nav-link-wrapper:hover {
border-bottom: 1px solid black;
}
.nav-link-wrapper a:hover {
color:black;
}
Why do I have to specify a that is within the class, to apply color, when I don't have to for manipulating borders.
Sry if it was asked. This is more of a beginner's question and I can't find anybody who already asked this.
If you set color in .nav-link-wrapper:hover, it will not affect since a tag has its own style. So in order to add style for that a tag, you will need to specify a.
If you see why you have to explicitly use a color property for your a tag is because of the Browser specific color property being applied on it. color and text-decoration is applied to it explicitly as shown in the image snippet below:-)
And that is true only with color property not with any other property. In the code snippet below I am setting font-size for the body and it is applied on the a tag.
body{
color:orange; /* Parent Not applied */
font-size:2rem; /* Applied to Child*/
}
<body>

</body>

I do not want my innerDiv to get modified by CSS in outerDiv.
Is there some way to achieve this?
(contents(HTML) of InnerDiv are loaded via ajax call , and the resulting page already has its own CSS and both CSS files are messing up all the layouts and formats)
From a previous answer: all: initial isn't supported by Edge (Safari is finally OK)
So you can reset manually a hundred of properties if you really really really want to be sure (forget the most obscure ones you know you don't use. If you're a third party, well no luck).
You can (should) add the !important modifier (that's one of those cases where it isn't possible to do in some other way... Fine for me at least)
You can also add a whole lot of specificity to your selectors by adding an id to your component's parent and prefix each of your selectors with that id: #myComponent.my-component .my-component-descendant { color: #333 !important; }. If your existing CSS already uses id (meh), you can go even further (lower, quality wise) and use the same id multiple times in a single selector. #myComponent#myComponent#myComponent.my-component .my-component-descendant { color: #333 !important; }. What is one the crappiest thing you can imagine in a sane project is also a powerful tool when you need to add "enough" specificity.
Food for thought: the modern way of setting box-sizing by setting it on :root and then letting inheritance do its job can be helpful (or not) https://css-tricks.com/inheriting-box-sizing-probably-slightly-better-best-practice/
Advantage: if you set another value on a descendant, descendants of the latter will inherit from it. You now have a whole part of your DOM inheriting from another value.
You can override the properties in you innerdiv; here I have overwritten the background-color property of the outerdiv
#outerMostDiv {background-color:red;}
#innerDiv {background-color:yellow;}
<div id="outerMostDiv">
<!-- SOME CSS HERE (say Outer CSS)-->
outer div
<div id="innerDiv">
<!-- some CSS HERE -->
innerdiv
</div>
</div>
I have a sap.m.Input inside a div tag in HTML view of sapui5. When I apply css to the div, it works fine on all the div elements. However, I want to apply css on a single control inside the div tag. It is not working. The code is :
<div data-sap-ui-type="sap.m.Label" data-text="Sr.No :"></div>
<div data-sap-ui-type="sap.m.Input" id="id_SrNo_Val" data-width ="10%"></div>
The above code does not work if I apply css to the input. It works fine on the label. I am trying to reduce the height of the input. It works on Chrome console with runtime id. However I want to apply css with the given id which it does not accept.
Please help.
In SAPUI5 we don't know at which point time of CSS is applied to the Controls.
So you've to give "priority to your css class or id" which can be achieved using the property !important
Add your CSS property like following
#id_SrNo_Val {
height : 10px !important;
color : blue !important;
}
Use anything you want with !important property.
Update: Avoid !important because it'll become harder to debug at some point of time. Also in CSS, it's not suggested to use.
You may assign additional class to a control adding class="yourStylingClass" attribute.
You shouldn't use control ids for styling, since SAPUI5 may modify those, add prefixes etc.
I'm scraping this news website: http://www.nu.nl/
If you open console and type:
$('*').css('background', 'none');
You will see all the background properties being removed, except for one which is the "blue" squire in the first article. When I trace the original CSS I see it has the !important declaration assigned to it. I don't know whether this is causing its persistence. What can I try to get rid of that blue background in terms of Jquery and Javascript or CSS?
Please note I don't want to target the element itself but rather keep using the all (*) selector or some Javascript equivalent.
jQuery doesn't recognize the !important attribute in css definitions. You just need a more specific hierarchical selector here. Simply make a new class, and then use addClass.
$('head').append('<style type="text/css">html #page .noBG{ background:none !important; }</style>');
Then just add that class to everything.
$('*').addClass('noBG');
Edit
Based on comments below, you could try
$('head').append('<style type="text/css">html body#noBG *{ background:none !important; }</style>');
Then add the ID to the body
$('body').prop('id', 'noBG');
Which is a pretty specific selector. Some rules may still pass this, and you'll have to experiment with different variations depending on the scenario.
I have a PHP page that is bringing in results from a Database and displaying them on a page. Certain images have a red 'ball' to the left of their name to dictate that they have more information to be seen.
For example, there is 30 on one page, 12 of which have a red ball. I need to be able to manipulate the positioning of the first ball and leave the others as they are.
<img class="premium-icon" src="../../images/ball.png" alt="Premium Listing" />
<a href="page.php?cmd=auth&src=book&id=968365&a=CVTYJH5kavEbhwSDs" target="_blank" alt="" title="">
<p><span style="">Result</span></p>
</a>
This is how they are layed out, each image has the same class and I'm unable to stop this.
I'm looking for a pure CSS solution, however a Javascript one would be appreciated.
Thankyou for any help.
EDIT
A little bit more information, all of this is brought in from a Database so I don't know if in the final product the first image will even have a premium-icon. This is all in case that image does, as that image needs to be moved. So, it will always be the first-child as I'm only trying to select the first ever premium-icon.
You can use the first-of-type pseudoclass: http://jsfiddle.net/WAG6e/.
Edit: As BoltClock mentions, :first-of-type ignores the class, so actually you'd need to build your HTML such that the first img is the one you want to style. Then, it's a matter of specifying the tag name:
img:first-of-type {
border: 1px solid red;
}
The pseudo-class that you are looking for is the :first-child. According to w3schools, it works on all major browsers, since you have a <!DOCTYPE> declared.
So, a sample CSS to your problem:
img.premium-icon:first-child {
margin-left: 10px;
}
Remember that if your img isn't the first child on the results container, then the desired pseudo-class will be :first-of-type, but it only works on IE9+.
But, as pointed by #ptriek, :first-of-type can't be used together with class names. Then, you would need to change your HTML.
Personally, what I always do is a class name like .first on the desired element, set on my serverside code, so my CSS will be simple and working on all browsers:
img.premium-icon.first {
...
}
What about img:first-child { ... } ?
$('.premium-icon:first')
use that
Assuming class "premium-icon" is reserved for the relevant pictures, this JS could help:
var a=document.getElementsByClassName("premium-icon");
if (a) if (a.length>0) {manipulate_image(a[0]);}
