Has anyone ever encountered a case where a more specific !important declaration is not overwriting another !important declaration? Here is the base css:
.x-floating {
position: absolute !important;
z-index: 10000 !important;
}
And here is what I want to use to override the z-index:
.x-msgbox.x-floating {
z-index: 10001 !important;
}
When I inspect via the Chrome (or Safari) debugger on Windows, I see the .x-msgbox.x-floating declaration being overwritten (crossed out), and the x-floating declaration being active. This goes against what I know of css specificity, and what I expect from simplified tests.
Example code:
Since I'm using Sencha, this will only work in Chrome or Safari, but here's a jsFiddle link (perhaps not kosher to hotlink Sencha's source, but this'll never get enough views for it to matter at all). To run the test, click the "choose date" button, then spin one of the wheels by dragging. A message box will appear. Compare the message box with the date picker (the top level elements of each — children of the body; another way to do it is to look for elements with class x-floating).
Default position is static. In static position can´t use z-index.
.x-msgbox.x-floating {
position: relative;
z-index: 10001 !important;
}
!important sets the highest priority for that css
why .x-msgbox.x-floating? and not .x-msgbox only.
the first time you give .x-floating the highest priority, so the next time there is important (z-inbdex.10001) this time it is ignored.
the first !important can be deleted
why not creating a new class and overwriting it again directly with the new value?
and x_msgbox would maybe also better

I am using Wordpress and WPbakery. I have set a full-width, full-height background. But currently the background-position is set to centred with '!important' assigned as I see in the developer tools.
I want to set it to 'top'. I edited in developer tools in chrome and I achieved the desired effect. However I'm not sure how to make the changes permanent. I have tried copy pasting what I saw in the developer tools into the custom css field and editing it to 'top' but it wont override the theme. How do i go about it?
This is the current code seen in developer tools:
.vc_custom_1551104319445 {
background-image: url(https://unlicensedshrink.com/wp-content/uploads/2019/02/ulweb.jpg?id=9) !important;
background-position: center !important;
background-repeat: no-repeat !important;
background-size: cover !important;
}
Not sure in which order custom styles and the default CSS of the theme are output … try increasing the specificity of your selector, f.e. like html .vc_custom_1551104319445 or .vc_custom_1551104319445.vc_custom_1551104319445
When multiple CSS rules apply to an element and try to specify values for the same properties, it becomes a matter of specificity, which one “wins”.
Here are a few resources on that topic:
https://www.smashingmagazine.com/2007/07/css-specificity-things-you-should-know/
https://developer.mozilla.org/en-US/docs/Web/CSS/Specificity
https://specificity.keegan.st/
So if you try to overwrite something using the exact same selector you took from the WP/themes styles, it becomes simply a matter of order. Do the WP styles get embedded last? Then they win, otherwise yours would.
A simple way around that, is to increase the specificity of your selector. Selecting elements of this class on the additional “condition” that are descendants of the html element is one way to do that. Or to repeat the class name, so that .foobar becomes .foobar.foobar … and lots of other possible ways.
You need to see which file is producing the code. For instance -
After you know which file is responsible for the code, then you go to the site directory and implement the file in question.
I wouldn't suggest using the vc_ number selector. Best to use or even better add a custom selector on the row or element itself and then apply the following CSS.
.has-bgimg-right.vc_row-has-fill{
background-position:center right !important;
}
What ends up happening if you use the vc_ number selector is if you or your client go to update that field the vc number will change and you will be shaking your head. So create a custom selector class and use the vc_row-has-fill which will never change.
Is there a way to change the default block cursor used by Shellinabox to a vertical bar?
Using Chrome's inspector tool, I found this div:
<div id="cursize" style="left: 675.5px; top: 160px; visibility: hidden;">143x20</div>
but altering the value does nothing.
There is nothing about a cursor size in the page's styles.css file or any of the config files found in /etc/shellinabox/options-available.
If you know of a better place to ask a question like this, please tell me.
Those inline styles have been generated dynamically through means of something like JavaScript. Considering they are generated dynamically, simply manipulating their values won't reflect any change.
Having said that, you can override them with the !important declaration. Typically !important should only be used as a last resort, but inline styles have the second-highest level of specificity, and !important is the only way to override them.
Using something like the following should work for you:
#cursize {
left: 500px !important;
top: 100px !important;
}
Hope this helps! :)
I've got a DIV covering the entire document:
<DIV style="position:'fixed';left:'0px';width:'100%';height:'100%';top:'0px',z-index:-20">
The zIndex of -20 is to prevent the DIV from coming up on top of other elements and interfering with mouse events.
However, when the page is busy with an asynchronous request, I want to bring the DIV to the top. My async request function sets the class of a user-defined variable element to "AJaXBusy" and then I style that class however I want. However, in this case, the style of "zIndex:100" isn't working, because the default value of -20 is overriding it!
Here's the code I'm using the show the DIV:
css('.AJaXBusy').backgroundColor="#ffddff"
css('.AJaXBusy').zIndex='100 !important'
(The CSS function returns a style-sheet object style property, it's about 30 lines of code so I have omitted it.)
How do I get a CSS class definition to override the value that has been assigned directly to the element? I've read about specificity and inheritance, but it didn't seem to address effects applicable in the document itself.
If you use JS to set element style (i.e. ele.style.zIndex), then '100 !important' is not a legal value (while '100' is), so the expression silently fails.
However, if you use ele.setAttribute('style', '.....'), then !important could be applied.
And, inline style has much higher previledge than css class, so you cannot override it.
A much better approach would be, if you could edit HTML, use different class definitions.
<style>
.undercover { z-index: -20; }
.cover { z-index: 100; }
</style>
<div class="AJaXBusy undercover">
Then change class name when you want to make it
var ajaxBusy = document.querySelector('.AJaXBusy')
ajaxBusy.classList.remove('undercover')
ajaxBusy.classList.add('cover')
use !important after your declaration.
z-index:100 !important;
As others have said, zIndex is how you update the property in javascript, elsewhere you refer to it as z-index.
I would recommend that instead of using a negative z-index to attempt to stop it interfering with the page, leave the z-index high, and hide the DIV using the css display:none; and only show the DIV when you want it to block page interaction (during AjaXBusy).
In IE10, a focused textbox containing a value will have a little x added to the right of them. This x allows a user to click on the textbox in order to clear its value.
Other questions have touched on removing this feature from the user's view, but I wanted to maintain the feature in addition to adding my own icon to the right of the textbox, such as a search icon. Unfortunately, those icons end up colliding, so I needed to determine a way to move the icon and my searches never turned up any results.
The question that I kept trying to answer: what other properties can be used with the IE10+ ::-ms-clear pseudo-element?
UPDATE: As the other answerer pointed out, the MS documentation has been updated as June 19, 2013 to include all of the properties available to ::-ms-clear. It's unclear if this applies to IE10 rather than the currently forthcoming IE11, so I will leave the rest of the answer below.
For completeness, they have also updated the documentation for ::-ms-reveal, which appears to be the exact same as ::-ms-clear.
The answer below at least applies to IE10.
I cannot find an exhaustive list, which lead me to experimentation:
::-ms-clear {
margin: *; /* except margin-left */
background: *;
color: *;
display: none|block;
visibility: *;
}
Unfortunately, I was not able to trick IE's developer mode (F12) into showing me the ::-ms-clear properties in the style tree, so I had to try things by hand and reload the page in order to experiment. I even tried cheating by adding onblur=this.focus(), but that did not work.
CSS properties that did something, and seemed useful:
margin: The margin gave me a way to shift it from the right side of the textbox. I shifted it by the size of my icons, plus 1-3 pixels to give a buffer. Only margin-left does not seem to work.
background: The background of just the x. Applying any background settings puts your desired content behind it; it does not replace the x!
color: Controls the color of the x.
display: As the question that got me here notes, none will hide the x.
visibility: Seems to work as one would expect similar to display.
You can combine the color and background to replace the x with a different background image so long as it fits within the given size of the x, which appears to be around 20px, but that is just me eyeballing it.
::-ms-clear {
color: transparent;
background: no-repeat url("../path/to/image") center;
}
CSS properties that did something, but did not seem useful:
padding: It affects the x, but never as I actually expected its effect (everything seemed to hide the icon, or at least shift it out of view).
position: Identical behavior as padding. Admittedly, I am much more of a programmer than a designer, so this may be my own shortcoming.
CSS properties that I guessed might do something, but that did nothing at all:
text-align
float
Adding other CSS pseudo-elements does not affect ::-ms-clear. Specifically, I tried ::after and ::before on it with content: "y", and neither one got a result.
Obviously it depends on the size of the companion icon that you intend to apply to the textbox, but I use 14-16px icons and I found that margin-right: 17px gave the x a clear gap, which shifts the x to the left of my right-aligned icon. Interestingly, margin-left seems to have no effect, but you can use a negative value for margin-right.
The actual CSS that I ended up using, which prevented my icon from being covered by the x.
[class^="tbc-icon-"]::-ms-clear, [class*=" tbc-icon-"]::-ms-clear {
margin-right: 17px;
}
My icons all share the same base name, tbc-icon-, which means that the ::-ms-clear pseudo-element is automatically applied to all of them whenever they are applied. In all other cases, the pseudo-element behaves in its default manner.
Of interest, ::-ms-reveal seems to behave the same way, and if you were going to apply icons to password fields (far less likely I expect), then you can follow the above example:
[class^="tbc-icon-"]::-ms-clear, [class*=" tbc-icon-"]::-ms-clear,
[class^="tbc-icon-"]::-ms-reveal, [class*=" tbc-icon-"]::-ms-reveal {
margin-right: 17px;
}
One list is available on MS site, at least.

(But maybe I misunderstood the question.)
Lets say I have a plugin's CSS which loads later as my style.css
/*style.css*/
.something {
position:absolute;
left: 0px !important;
}
/*plugin's CSS*/
.something {
position:absolute;
left: -50px;
}
/now it has 0px but i want no left value at all/
i know i can set !important so that property wont be overriden, but is there any solution to turn "left" off as Chrome DevTools uncheck a property?
As far as I am aware (someone please feel free to correct me) there is no way to directly "turn off" a CSS property like in the Chrome DevTools.
The closest you can get it to reset the property to its default. In your example, it would be "left:auto;"
P.S. You may wish to adjust your tags to get more views and hopefully answers.
You should use the "auto" value for left:
.something
{
position:absolute;
left:auto !important;
}
"auto" will reset to the default (that is set by browsers for that style)

Specificity is the key to selecting the CSS attribute that you really want. Leverage the specific structure of the HTML in the plugin vs. non-plugin case so that specificity rules select the CSS you desire when plugin rules should apply.
There's a great overview of specificity here:
Source: http://www.stuffandnonsense.co.uk/archives/css_specificity_wars.html
One thought that comes to mind is to use an additional class, plugin, along with an appropriate selector.
If you are trying to override it then you can play with CSS Specificity Rules
