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 am using HTML to input a cloud-based instagram feed on a website. I want to hide the bottom half of the feed that references the website of the publisher. The inline HTML that is outputting already has display: inline-block !important marked, so trying to hide it with display: none !important or visibility: hidden !important do not work. I am able to hide the entire block with CSS but not "parts" of it. I don't seem to be able to edit the HTML since it is coming from the cloud. The only HTML that I actually use on the site in order to make it render does not include any of the inline CSS, as it is only two lines.
Would someone mind explaining how this kind of thing works and why I am encountering issues overriding the inline CSS?
I have tried using:
display: inline !important, display: none !important and visibility: hidden !important
None of these are receiving priority, as the element.style in the chrome developer console clearly shows the inline CSS already marked as !important that I do not have access to, nor can I edit.
I simply want to hide one selector within the HTML. It is marked as "a"
a {
}
I have tried using this selector within the actual element, but it does not receive priority either. Nothing is working.
Try to remove the inline style with jQuery
$("#myDiv2").css("transform","");//used rotate to see the effect
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<div id="myDiv1" style="width:100px !important; height:100px !important;transform:rotate(30deg) !important">
//Some Content
</div>
<div id="myDiv2" style="width:100px !important; height:100px !important; transform:rotate(30deg) !important">
//Some Content
</div>
Setting the value of a style property to an empty string removes that property from an element.
$("#myDiv2").css("transform","");
Typically the only way to do this is to be more specific in your selector, for example selecting a[href][style] is more specific than just a. But since this is inline styles and already using !important you unfortunately might be out of luck!
a[href][style]{
color: green !important;
}

If you wanted to just remove the links without importing several thousand lines of jQuery code, you can select and remove all <a> tags with just a few lines of plain JS.
document.querySelectorAll('a').forEach(link => {
link.remove();
});

I have assigned an element a class which has following CSS:
.cls {
display:none !important;
}
When I try to show this element with jQuery
$(".cls").show();
It does not work.
How can I show this element?
$('.cls').attr('style','display:block !important');
DEMO
Although question has been asked long back but its still relevant for new coders/beginners. Generally this situation comes when you have already applied some class which overriding the display behavior using !important property.
Other answers are also relevant to the question and its a matter of achieving the same goal with different approach. I would recommend to achieve it using already available classes in the same library (bootstrap here), instead of writing custom class as these days when most of us are using Bootstrap classes to build the layout.
<div id='container' class="d-flex flex-row align-items-center">
.....
</div>
If you see in the above code, we are using d-flex class for setting display property of this container. Now if I am trying to show/hide this container using
$('#container').show()
or
$('#container').hide()
It will not work as per expectation because of
As d-flex is already using !important property
Jquery's show() method will add display:block not display:flex to the css property of container.
So I will recommend to use hidden class here.
To show container
$('#container').removeClass('hidden')
To hide container
$('#container').addClass('hidden')
2 ways of doing this,
1) Remove the !important from your .cls class,
.cls{
display: none;
}
But I assume, you'd have used this elsewhere so it might cause regression.
2) What you could alternatively do is, have a another class and toggle that,
.cls-show{
display: block !important;
}
And then in your javascript,
$('.cls').addClass(".cls-show");
Then when you need to hide it again, you can,
$('.cls').removeClass('.cls-show');
This will help you keep your markup clean and readable
!important; remove all rules and apply the css desfined as !important;. So in your case it is ignoring all rules and applying display:none.
So do this:
.cls {
display:none
}

If the only property in the CLS class selector is the display one, you can do this and don't need to add any extra classes or modify the inline style.
To show them:
$('.cls').removeClass("cls").addClass("_cls");
To hide them:
$('._cls').removeClass("_cls").addClass("cls");
Just had this exact issue, here's what I did
first, I added another class to the element, such as:
<div class="ui-cls cls">...</div>
Then in the javascript:
$('.ui-cls').removeClass('cls').show();
The nice thing is that you can also have this code to hide it again:
$('.ui-cls').hide();
and it doesn't matter how many times you hide/show, it'll still work
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 found out that if we write inline css (or add it using JavaScript), then we lose the value of css hover. Is it possible to change such behavior?
Simple example
<div id="test" style="color: red">test</div>
<style>
#test:hover {
color:blue;
}
</style>
In this case hover doesn't work.
Update
I can't use !important, because after it I will not be able to change that atribute via JavaScript.
Also I generate styles dynamically, so I can't add specific classes via JavaScript.
because inline css overrides your css styles in the file
if you had
color: blue !important
it would work but not recommended, you can always use jquery to remove the inline style tag though haha
Update:
remove the style tag using jquery or when using javascript... add !important so the inline css would have important
I can't use !important, because after it i will not be able to change
that atribute via javascript.
You can still use !important, just add a class with JavaScript and remove it anytime you want.
demo
The easiest way to go is the following
$(selector).hover(function() {
$st = $(this).attr("style");
$(this).attr("style","");
},function() {
$(this).attr("style",$st);
});
In CSS, the style attribute will override any style elements or stylesheets. If you cannot change the the style attribute, you'll have to use !important. If you can remove the style attribute altogether and place everything in the style element. Or even better, in a separate stylesheet your problem will be fixed.
P.S. The type attribute is required on style elements. This won't fix your problem, but you should change <style> to <style type="text/css">
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.
