I trying to hide the element before replacement by using the .sIFR-active class, set on the HTML element, to apply CSS rules to elements when sIFR is active. I set the visibility: hidden; and it is working fine in IE and Firefox. Not Safari.
Any idea?
.sIFR-alternate {
display: none;
}
The .sIFR-active class might be set on either the <html> or the <body> element. If your CSS rule is explicitly html.sIFR-active it won't trigger if it happens to be added to the <body>.

It seems I'm not able to drag an element that has unset: all css property.
.my-component {
all: initial;
* {
all: unset;
}
}
I use these rules inside a chrome extension, on elements that are being injected in the user browser page (to prevent local style affecting my component). Unfortunately, elements are not draggable anymore.
Those elements have the draggable property on in html.
I tried pointer-events: auto;, -webkit-user-drag: auto;, user-select: all; but I still can't manage to make elements draggable.
There must be some properties I have to set back to normal.
If someone had an idea, I would highly appreciate any help on this topic.
Edit : see this codepen - https://codepen.io/thomaslh/pen/OgQNMz
Looks like you need to add 2 CSS properties. user-select and -webkit-user-drag
.el {
all: unset;
-webkit-user-drag: element;
user-select: none;
}
<div class="el" draggable="true">
drag
</div>
I was just playing around with CSS and noticed an interesting scenario for which I couldn't really find an explanation. Maybe some of you have the answer for this.
I have a div element with an inline styling
<div id="text-sample" style="overflow:hidden;">This is a sample text to test the CSS behavior of inline styling</div>
My CSS
#text-sample {
width:200px;
white-space: nowrap;
}
#text-sample:hover {
overflow:visible
}
Here the hover effect is not applying. That is, the overflow: visible rule is not taking.
Note: Moving the overflow:hidden from inline style will fix the issue.
I'm looking for the reason why hover effect is not applying. Can anyone explain this scenario?
All else being equal, inline styles take precedence over styles applied via stylesheet rules. In your case, when hovering, the overflow: visible is invoked via the stylesheet rule, but that cannot override the inline style. If necessary, you could try !important.
#text-sample {
width: 200px;
white-space: nowrap;
}
#text-sample:hover {
overflow: visible !important;
}
<div id="text-sample" style="overflow:hidden;">
This is a sample text to test the CSS behavior of inline styling
</div>
But it would be easier simply to specify overflow: hidden in the #text-sample stylesheet rule, instead of giving it inline.
Your inline style will always override your external CSS.
You can use !important in :hover
#text-sample {
width:200px;
white-space: nowrap;
}
#text-sample:hover {
overflow:visible!important;
}
Inline styles take precedence over style sheets. There are two ways to change that: using JavaScript or using !important in the style sheet.
#text-sample:hover {
overflow:visible !important;
}
In CSS, there's something called Specificity. Simply said, something like
#id { color: red; }
would take precedence over something like
.blue { color: red; }
when having something like <div id="id" class="blue">. See example below.
This is because an ID selector (#) is interpreted as more important than a class. In the same manner, an equally specific selector with a later declaration (later in the file) takes precedence and the more specific your selector gets, the more important it is.
For your example: An inline-style takes precedence over anything written in a CSS file (unless using !important). I believe the :hover does not change anything on that fact.
For the detailed rules look my link above.
div {
width:200px;
white-space: nowrap;
}
#text-sample:hover,
#sample-2:hover {
overflow:visible;
}
#sample-2 {
overflow: hidden;
}
#foo {
color: red;
}
.blue {
color: blue;
}
<div id="text-sample" style="overflow:hidden;">This is a sample text to test the CSS behavior of inline styling</div>
<div id="sample-2">This is a sample text to test the CSS behavior of inline styling</div>
<div id="foo" class="blue">foo</div>
EDIT
As mentioned in comments, Specificity does not apply to inline styles. Nevertheless, inline styles are taking precedence over anything in a CSS declarations in files. However, as soon as you move the rule into the same CSS file (as you mentioned will work), the :hover is more important than the other rule since it is more specific in the moment you're hovering.
I'm trying to hide the text of this content:
<div class="avrow">Powered by Altervista Mailing List</div>
I tried:
.avrow > .avlink disclaimer > a
{
visibility: hidden;
}
not seems to working anyway, how can I fix this?
Your a tag has the class .avlink and .disclaimer. So the order of your CSS is wrong and if you have 2 classes on one element, you will need to append both class names.
.avrow > a.avlink.disclaimer {
display:none;
}
<div class="avrow">Powered by Altervista Mailing List</div>
If you are trying to hidde an specific element, you can try the next ones:
By Css
display: none
By HTML´s tag:
<div hidden>Your element, could be others elements as well</div>
The problem is that the .avlink class is not a child of a, but at the same level.
The following will achieve what you're going for:
.avrow > a.avlink
{
visibility: hidden;
}
See http://jsbin.com/holivirofe/edit?html,css,js,output for a working example.
Here you are:
.avrow {
display: none;
}
.avrow > a
{
visibility: hidden;
}
You could also take one of the class names like I did below.
.disclaimer {
display: none;
}
.disclaimer {
visibility: hidden
}
There two common ways of hiding elements in CSS. The first is the visibility property that you have been using. This simply hides the element but maintains it's properties such as size and margins. Therefore it has the effect of looking like it is not "hiding" the element correctly.
The other way is using the display property. By setting the display property to hidden it efectively renders the HTML as if the element is not there. This means the other elements are not affected by the hidden one.
Also your css selector is incorrect, it suggests there should be an anchor element below .avlink. Your selector should actually be:
.avrow>a.avlink.disclaimer
I need to disable the mouse hover on a particular button(not on all buttons) in the entire DOM. Please let me know how to achieve it using a CSS class.
i am using the below CSS class when my button is disabled. now i want to remove the hover effect using the same class.
.buttonDisabled
{
Cursor:text !important; Text-Decoration: None !important;
}
The above class will take care of removing the hand sign and text underline on mouse over . Now i want to remove hover effect also. Please let me know.
I have really simple solution for this.
just create a new class
.noHover{
pointer-events: none;
}
and use this to disable any event on it. use it like:
<a href='' class='btn noHover'>You cant touch ME :P</a>
You can achieve this using :not selector:
HTML code:
<a class="button">Click me</a>
<a class="button disable">Click me</a>
CSS code (using scss):
.button {
background-color: red;
&:not(.disable):hover {
/* apply hover effect here */
}
}
In this way you apply the hover effect style when a specified class (.disable) is not applied.
Here is way to to unset the hover effect.
.table-hover > tbody > tr.hidden-table:hover > td {
background-color: unset !important;
color: unset !important;
}
For this I ended up using an inline style because I only wanted the one particular element not to have any hover on-click event or style due to it just being part of instructions regarding the other buttons that looked like it on the page, and to give it override precedence. Which was this:
<button style="pointer-events:none"></button>
This removed all styling and bound JavaScript/JQuery functionality on the single element for me, while not affecting the others on the page :). For more info see the mozilla reference.
To disable the hover effect, I've got two suggestions:
if your hover effect is triggered by JavaScript, just use $.unbind('hover');
if your hover style is triggered by class, then just use $.removeClass('hoverCssClass');
Using CSS !important to override CSS will make your CSS very unclean thus that method is not recommended. You can always duplicate a CSS style with different class name to keep the same styling.
From your question all I can understand is that you already have some hover effect on your button which you want remove.
For that either remove that css which causes the hover effect or override it.
For overriding, do this
.buttonDisabled:hover
{
//overriding css goes here
}
For example if your button's background color changes on hover from red to blue. In the overriding css you will make it as red so that it doesnt change.
Also go through all the rules of writing and overriding css. Get familiar with what css will have what priority.
Best of luck.
Do this Html and the CSS is in the head tag. Just make a new class and in the css use this code snippet:
pointer-events:none;
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
<style>
.buttonDisabled {
pointer-events: none;
}
</style>
</head>
<body>
<button class="buttonDisabled">Not-a-button</button>
</body>
</html>
Add the following to add hover effect on disabled button:
.buttonDisabled:hover
{
/*your code goes here*/
}
Use transition: all 100s ease-in-out; to override the hover change. This is not a solution but a workaround if you do not know the original value of the property which you want to replace.
Other solutions didn't work for me.
I simply changed this
.home_page_category_links {
color:#eb4746;
}
to this:
.home_page_category_links, .home_page_category_links:hover {
color:#eb4746;
}
That means the same styles that are applied to elements of that class are also applied to elements of that class when hovered.
Extra note: If you're keeping the colour the same, perhaps you may also want to avoid any underline, if so, just include text-decoration: none; as well (or text-decoration: none !important; if using bootstrap).
I tried the following and it works for me better
Code:
.unstyled-link{
color: inherit;
text-decoration: inherit;
&:link,
&:hover {
color: inherit;
text-decoration: inherit;
}
}
What I did here is that I make the hover effect on the button but doesn't apply to the button that has the disabled class
button:hover:not(button.disabled){
background-color: rgb(214, 214, 214);
color: rgb(0, 0, 44);
}
Problem which I understood - Well I was doing something the same as yours. I have used four links among which two of them will hover and the other two will not. Now that I have used the a tag(hyperlink tag in HTML) to use hover, all my hyperlinks start hovering, which I don't want.
So, I put the two a tags which were not supposed to hover inside the same class, say .drop, and use the class to specify that I want all a tags inside the dropped class not to hover but the other a tags do.
To do so, I just wrote a CSS
a:not(.drop):hover {background-color: limegreen}
what I meant here is that apply a hover to all the tags but not the ones which are inside the .drop class.
Hope that helps!
#Simone Colnaghi was the first to mention it, and it worked for me too.
I have also faced the similar problem but the below method works for me.
Lets suppose you have two class, wantsHover and dontWantsHover just use:
.wantsHover:not(.dontWantsHover):hover {
background-color: red;
}
I'm trying setting up two simple css classes to toggle elements :
.hide{
display:none;
}
.show{
display:inherit;
}
It seems to work but sometimes display:inherit; return troubles so which is the exact opposite of display:none; ?
This all depends on the element you are specifying. For example <div> and <p> elements are display:block; by default, whereas <span> is display:inline; by default.
The accepted answer here provides a list of the defaults for each element based on what browser is being used.
EDIT
It appears that display: initial; will work in most browsers, although not IE. A fallback line of CSS would probably be best practice:
.show {
display: block;
display: initial;
}
If you use Javascript to do that:
document.getElementById(id).style.display = "";
And
document.getElementById(id).style.display = "none";
Can toggle the display for you.
If you are just toggling elements, you don't need two classes; you just need one class ("hide") that you add and remove for each element. When you hide the element, you add class "hide" to it, and when you show the element again, you remove class "hide".
However, if you really need two classes, I've had success with something like this:
.show{display:"";}
The blank value tells the browser to ignore that property, and it goes back to its default value.
It depends on which element you want to show, for block elements:
.show{
display: block;
}
