Margin in angular global styles are not enforced - css

I created a global CSS file. It is working perfectly, except that I am unable to set margins.
For Example CSS:
.update_date {
font-size: small;
text-align: right;
margin: 0;
}
This is a CSS style for class update_date. When I use it, except margin, everything is applied. It's the same case with every other class. None of these classes are overridden in any other place.
Can someone provide a workaround on how I can set margins globally.
Environment:
Angular 10/11

Try using
.update_date {
font-size: small;
text-align: right;
margin: 0 !important;
}
this happens because that style is getting overridden by another

You should avoid "!important" if you can. It can cause unintended styling issues later down the line - see below.
My suggestion: In your browser, use your "Inspect Element" (Ctrl + Shift + I) tool to figure out where in the DOM Tree your styling is coming up and what is overriding it. This will help identify if !Important is truly the only solution you can use.

Hard to say with your code snippet what is actually happening and being this post is 1.5 years old, you may already know this info. But I didn't see any other responses, so just wanted to raise awareness to the "!important" property.

From W3 Schools (I am sure you can find this elsewhere as well): https://www.w3schools.com/css/css_important.asp
"Tip: It is good to know about the !important rule, you might see it in some CSS source code. However, do not use it unless you absolutely have to."

Change shellinabox cursor configuration

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! :)

How to break CSS inheritance?

I have created a web widget. That my client put in their websites. Basically on load it calls webservice and loads data specific to client.
As a result it looks like:
<div class="widget">
<div class="container">
</div>
</div>
Dynamically I apply CSS styles to my widget class. To look consistent with our corporate styling.
The problem is when client application styles overwrite the style I applied run time.
For example if client has, it overwrites my styles:
body {
margin: 0 auto;
padding: 0;
width: 90%;
font: 70%/1.4 Verdana, Georgia, Times, "Times New Roman";
}
Is there any way to break inheritance? Just to say whatever div with class widget styles has do not inherit parent styles.
I don't think you can break CSS inheritance per se, but you can try to circumvent it by following the rules of CSS specificity. Here's a good article about Specificity.
As a last resort, try adding !important to styles in the widget to give it a higher specificity than the default styles.
#myWidget{
font: 100%/1 "Times New Roman", Serif !important;
}
If the client is also using !important it could cause problems. If you could setup a jsFiddle with an example, we could help find the issue.
Note, going the route of adding !important should be a last resort as it's the 'nuclear option' of style specificity.
You can not force elements to NOT inherit parent styles.
You can however override all possible styles that you do not want changed. If your CSS specificity is higher than the customers specificity then your styles will be dominate/expressed on the page.
See:
CSS Specificity via css-tricks.com
Per your example using the code below would be more specific than the body declaration and thus override :
.widget .container {
font-family: Arial;
}
You can't break style inheritance as such, but you can ensure that your styles are either more important or loaded in the right order so yours comes out on top.
Have a look at the !important tag.
Alternatively if you load your stylesheets after theirs yours will take precedent (unless theirs is inline). You can use Javascript to load your styles after the body has loaded (But then you'd get a "flicker" effect).
You could also try inline styling. Inline styling has the highest priority. This will work if client overrides use an imported stylesheet.
Like others have mentioned, another option is !important.
You can also read up the relevant specs at http://www.w3.org/TR/CSS2/cascade.html where they describe exactly how they cascade. If above mentioned tricks don't work, perhaps specs will give you a clue or you will know for certain that this is not possible.
Use of the !important css attribute is considered a bad practice. Because it introduces the potential for precedence conflicts, and makes it extremely difficult to troubleshoot css in the long run.
A less intrusive approach to this problem is to delimit your widget with an id, and in your stylesheet, to reset some of the most important style declarations using the "universal" selector, such as:
#myWidget *{
margin: 0;
padding: 0;
background: none;
border: none;
}
For example. Then, define your overrides specifically.

Please explain me Eric Meyer's CSS reset

First of all I want to tell you why I'm asking this question. I usually update projects that have been written poorly and without a reset. I want to improve the project's quality so it seems that applying a CSS reset is absolutely necessary.
I don't want to do a hard work of pixel perfect testing in every browser every time I change something and I don't want to completely rewrite all CSS.
So:
When I'm writing:
*{
margin:0;
padding:0;
border:0;
}
I know what trouble to expect: <p> will loose padding and <input>, <select>, etc. will loose padding and border. So I have to specify them manually.
This code is more difficult to understand:
*{
font-size: 100%;
font: inherit;
vertical-align: baseline;
}
And I'm completely confused with this:
body {
line-height: 1;
}
*{
font-size: 100%;
font: inherit;
vertical-align: baseline;
}
This sets all elements in the document to inherit font and font-size from parent elements by default unless specified otherwise, which can prevent user-agent stylesheets from applying font styles with less specific rules.
vertical-align: baseline; is another widespread rule to avoid user-agent rules which don't always apply this (I believe) expected default behaviour to all elements.
Here's a brief look at what this does: demo. In the demo, try setting a rule to middle rather than text-top.
body {
line-height: 1;
}
This is the same. If you're not familiar with line-height, it's quite simple. You may have dealt with it without realizing it: Sometimes it appears to be a margin issue when in fact, the line height of an element is exceeding what you expected. This often happens when you place a typeface into a design which has a very dissimilar x-height to other typefaces.
If you don't understand its function, throw some dummy text into a document and start playing with it. It's very useful (essential) for producing good typography in different situations.
It seems you're not clear on css attributes and how they effect elements. The better your understand this, the better you can utilize a reset. No reset really fits all for a few reasons. For example, you might not be using any elements where vertical-align may end up being mismatched. You may have rules in a large reset that apply to elements you don't even have.
As with anything in web design, if you don't understand it, hands on experience will teach you a lot.

Toggle reset and see how input font and font size changes.

css hover not working

Can you have a look at my code and please tell me why the hover is not working, thanks!
<style>
#moreDiscussHome:hover{
background-color: #ffffff;
}
</style>
<a id="moreDiscussHome" style="color:#f1f7f8;background-color:#12a1b7;" href="">more discussions</a>
Well, as soon as display: none; is applied, you are no longer hovering the element because it is not there, so it will basically flicker constantly or do nothing.
Try opacity* instead perhaps:
#moreDiscussHome:hover {
opcaity: 0;
}
Note that the element still retains it's space in the layout with this, which may not be what you want... but I'm honestly not sure what you're trying to achieve with this.
Side note: There's no reason not to move those other inline styles to a stylesheet.
This doesn't work: #moreDiscussHome:hover{ background-color: #ffffff; }
EDIT: I strongly urge you to move all inline styles to a CSS file. If for no other reason, to avoid some of the issues you already seem to be having with trying to apply background colors. A shortcut might seem easier at the time, but as the saying goes: "Shortcuts make for long delays". (In other words, don't do it)
* visibility:hidden will respond to :hover the same as display:none, so it won't work either. Thanks to thirtydot for the tip.

-webkit-margin adds unwanted margin on texts

This hadn't hit me until now (and this is not only in webkit browsers). On all texts in like p tags, h1 tags etc... there's an extra space over and below the text.
In chrome I found this:
user agent stylesheet
-webkit-margin-before: 1em;
-webkit-margin-after: 1em;
-webkit-margin-start: 0px;
-webkit-margin-end: 0px;
This makes the alignment wrong in some places. And yes I'm using a reset stylesheet and no padding or margin are added. Pretty much a basic setup. Why is this and how do I solve it?
You can also directly modify those attributes like so:
-webkit-margin-before:0em;
-webkit-margin-after:0em;
Works for me in Chrome/Safari. Hope that helps!
These -webkit-margin(s) are overwritten by margin: 0; padding: 0;. Do not worry about them.
Extra space? Maybe you've set line-height:?
I had the same issue. Displaying correctly in Firefox but not Chrome.
I had a closer look at http://meyerweb.com/eric/tools/css/reset/ and found that I hadn't declared a general line-height for the body tag in my stylesheet. Set it to 1.2 and that recreated the correct layout in both browsers.
Just remove the whitespace between tags e.g.
<p id="one"></p>
<p id="two"></p>
becomes:
<p id="one"></p><p id="two"></p>
I had a same problem. Extra space between menu links. None of the above solutions worked. What worked for me, was negative margin.
Just do something like this:
margin: 0 -2px;
NEW EDIT:
This has nothing to do with -webkit-margins. Most likely your problem occurs with inline elements. This happens because you have spaces or line breaks between your inline elements. To fix this, you have many options:
remove all spaces and line-breaks between inline elements
skip element closing tag - for example </li> (HTML5 does not care)
negative margin (as stated above - problems with IE6/7 - who cares, upgrade ;)
set font-size: 0; to problematic inline element container (has issues with android and if font-sizing with ems)
give up inline and use float (this way you loose text-align:center)
Explained more specifically and examples by CHRIS COYIER
I was having this same problem with my <h3> tag. I tried setting margin:0;, but it didn't work.
I found that I was habitually commenting out lines in my css by using //. I never noticed it because it hadn't caused any problems before. But when I used // in the line before declaring <h3>, it caused the browser to skip the declaration completely. When I traded out // for /**/ I was able to adjust the margin.
Moral of this story: Always use proper commenting syntax!
For me, the picture was:
* {margin:0;padding:0;}
Firefox (FF) and Google Chrome both put 0.67em margins regardless.
FF showed its default margin, but crossed out, but applied it anyway.
GC showed its default margin (-webkit-margin-before...) uncrossed.
I applied
* {margin:0;padding:0; -webkit-margin-before: 0; -webkit-margin-after: 0;}
but to no avail, although GC now showed its default margin crossed.
I found out, that I can apply either
line-height: 0;
or
font-size: 0;
to achieve the desired effect.
This makes sense, if one assumes, that the margin is of the .67em - type.
If anybody could give an explanation, why browsers make our lives miserable by applying a line-height dependent, non-removable margin, i would be really grateful.
For me in Chrome it was some 40px padding-start that was causing this. I did the following that worked:
ul {
-webkit-padding-start: 0em;
}
-webkit-margin-before: 0em;
-webkit-padding-start: 0;
-webkit-margin-after: 0em;
This solved it for me when I was having this exact problem.
In your css file add the following.
* {
-webkit-margin-before: 0em !important;
-webkit-margin-after: 0em !important;
}
'*' selects all css elements and overrides the webkit-margin.
Modern properties
The following properties should be used instead.
margin-block-start: 0;
margin-block-end: 0;
It's very rare to need to use these at all, but the following can be useful to avoid extra space after the last paragraph in a series.
p:last-child
{
margin-block-end: 0;
}
I also found that even in Chrome you can trigger the 'ghost margin' by setting margin to inherit in some cases.
https://developer.mozilla.org/en-US/docs/Web/CSS/margin-block-start
I had the same problem. Suddenly one out of my three table cells containing data its header was moved down a little bit. My problem was simply solved by adding this:
table td
{
vertical-align: top;
}
Seems like some other element in a 'higher' style sheet was telling my data to center itself in the cell, instead of just staying on top.
I guess its just stupid, and wasnt really a problem... but the next person to read this topic might have the same stupid error as i did :)
Take care!
If user agent stylesheet is kicking in, it is because the tag property was not properly defined in your css stylesheet.
Chances are that a typo, forgotten bracket or semicolon is breaking up your stylesheet BEFORE reaching the tag property settings your page later refers to or "needs".
Run your CSS thru error checking, like CSS LINT and fix whichever errors are eventually detected.
