I'm using a button from a library (https://www.npmjs.com/package/#react-oauth/google I understand this library has a custom button option but this option results in a different response).
I basically like to change the max-width and width to another value (image attached below). May I know is there a way for me to edit these style from CSS?
Thank you! Appreciate any help.
Google adds this button to the dom inside iframe, there are certain props you can style the button
to add with, check prop width on
it's mentioned on #react-oauth/google github README
https://developers.google.com/identity/gsi/web/reference/js-reference#width
So still new myself currently in a full stack boot camp in the react section. It should be possible.
Are you using a external stylesheet or trying to do it using inline?
I was taught to use a external stylesheet
From what I am seeing try changing class name to button.
class='button'
Then in your external stylesheet add
.button {
max-width: 400px;
}
Edit. I see you are using react... So it could be className='button'
Edit:
Hello, thanks for your reply! Hmm... in this case I am not able to
assign a className to div myself as the div is from the library. The
weird class you see above "nsm7Bb..." is not by me. Hence, I was
wondering if there's a way to forcefully override library class style.

Gotcha.
Have you tried !important?
Is that your inline CSS?

I'm trying to override overflow for a div from hidden to visible. It's a large project and I'm trying to add some new things in this.
I'm able to apply css to the element using Inspect element console but the same thing doesn't work when adding to the file as internal stylesheet
Tried using !important as well
Please let me know what might be causing this.
Thanks in advance.
There's no reason for CSS not to work while using an internal stylesheet.
Here are two things to try, check if your class name is spelt correctly and you're using the correct selectors.
And you might have a fixed width or height which is causing the content not to be able to scroll over.
Post the code on here for more help if you can.

Is there any way to change the content of CSS node modules in Ionic React? I have created some external css for my App but the css in import "#ionic/react/css/typography.css" overwrites my css. For example, I cannot change some margins, text color, etc.
I also tried to change some css inside typography.css but the changes are not loaded in the app. It's like I have changed nothing inside typography.css.
The first time I'm working with CSS in an Ionic App and I feel really confused. Any help would be appreciated.
Ionic is using Shadow DOM, you can read more about it in their blog post. This feature is very useful to isolate components but it is also preventing you to modify the css from outside.
To fix this problem, Ionic introduced a lot of custom CSS Variables that you can use to modify the styling of each component. This is the best way to modify the CSS of an Ionic app.
You can also read about shadow parts in another blog post and he docs, but this is less recommended.
Because Ionic uses Shadow Dom you can override this with CSS with some Ionic Variables like
--background and --color
ion-button { --background: red; }
But many times the changes are not reflected in all the components of the Shadow Root
To modify the css of the Shadown Root you can use the pseudo element :: part as indicated in this publication CUSTOMIZE CSS SHADOW PARTS for example:
ion-button part is "native" so you can use
ion-button::part(native){
height: 100px;
width: 300px;
}
BACKGROUND: I have a set of webpages where clients can create their own emails (usually reminders for things) to be sent out to people. It uses ckeditor and I allow them to define their own style rules in a <style> tag. On another page, I show all of the emails they have drafted. (I basically just take what they made out of the database and output it into the page) I'm not asking about the security risks of this. I know perfectly well what they are and how to deal with them. That's not the question. The main problem is that if I have a class called .button that turns buttons to a navy color and they have some style defined for that same class in their css that makes the text black, then it leaks out and turns my button text black.
QUESTION: How do I let them preview what they wrote without letting their styles creep into my webpage and override my styles?
THINGS I'VE TRIED ALREADY: I've tried an iframe, but I can't totally figure out if it's possible to just embed code in it. I also have seen the <embed> and <object> tags, but I don't know if they could help either.
Thanks in advance for any help!
You could try wrapping each email html and css in its own Shadow DOM: https://developer.mozilla.org/en-US/docs/Web/Web_Components/Using_shadow_DOM
Shadow DOM is typically used just for this purpose, to help scope html and css. Popular frameworks like Angular make use of the Shadow DOM for this as well.
One way is using !important in your own CSS which makes your CSS codes default value which cannot be overridden. for example:
.button {
background-color: navy !important;
}
I am creating a mobile simulator that mocks the appearance and functionality of an iPhone (and other devices later) in a web browser, using 100% javascript, HTML5, and CSS, with the simulator fully functional with only client side code.
While trying to accomplish this task with as little modification as necessary to the original app projects themselves to be hosted in the simulator, I am injecting the <script> and <link> tags into the head of the page, then loading the html into a <div> screen.
The problem is that when I load in a new css file, it (obviously) overrides the one I'm using to style the page, and therefor some elements are affected (ex the background changes color).
My question is: Is there any way to limit the "scope" of an external .css file to apply only to objects within the <div> screen? Would it make any difference if instead of me injecting it into the <head> of the page, I inject it into a <style> element in the <div> screen?
UPDATE Support for this feature has been dropped. Please seek other options

You may want to look at scoped styles; see http://css-tricks.com/saving-the-day-with-scoped-css/.
The basic idea is
<div>
<style scoped>
#import "scoped.css";
</style>
</div>
However, you are on the bleeding edge here in terms of browser support. See http://caniuse.com/style-scoped.
One alternative would be to use an iframe.
Simply wrap all you css code inside the selector for parent element, say it's a div with id of foo you'd do the following:
div#foo{
//All your css
}
And convert it as less to css, it will prepend the right selectors. Note that you'll need to take care manually of things like #media queries and so on.
While writing this, the <style scoped> is deprecated by the Chrome team.
As a result I experimented with some approaches and released https://github.com/thgreasi/jquery.scopeLinkTags .
Note: you should only have to use this approach in case that you can't control the imported CSS file. If you can use SASS/LESS/anything to pre-process your CSS, you should prefer that.
A simple way is adding pre-class before all selector in css file.
I find a grunt script can do this:
https://github.com/ericf/grunt-css-selectors
This is how i do it if not using preprocessor in my project. Search for a online preprocessor then load copy paste the css under the parent class/id
.parent{
// copy paste here
}
Example
Find a preprocessor for example https://beautifytools.com/scss-compiler.php works very well for me (I have no affiliation with the given link)
if you are using from a URL add the URL using the load URL button.
Wrap the css code under parent and hit compile then minify.
I had a similar issue and found that Shadow DOM can solve it easily.
let output = d.querySelector('#output')
let shadow = output.attachShadow({
mode: 'closed'
});
shadow.innerHTML = HTMLcontent // HTML content and style injected

I am editing a HTML website template, and I need to change the banner height so I edited external CSS. However, somehow it is taking an inline CSS height property so there is a space left in between.
Please let me know, if I have not written any inline CSS (and there is no inline CSS in html page), from where is that height property coming from.
Code I see in console is:
<div style="display: block; height: 445px;" id="camera" class="camera-wrap camera_wrap">
And my code is:
<div id="camera" class="camera-wrap">
<div data-src="images/Battery-Banner.jpg">
I have no idea why it is taking class camera_wrap twice.
Usually JS plugins put dynamic css that is calculated during runtime. It will be placed in inline style tag. Otherwise any static code will go to external css file. Try checking how plugin is calculating that height and than modify your HTML/css.
Try viewing the HTML source in your browser (not using inspect element, use view-source). This will show you the markup prior to any other client side processing aka. JavaScript. If the inline style isn't there when you view source then that indicates that it may be a rogue bit of JavaScript that is adding it in.
In any case can you please provide more information on the issue? Possibly a little more background on what type of website, what parts it has CSS, JS etc. With more information we may be able to help more.
If your source is showing 1 class, and when you are using inspect element it is showing other classes, then it is definitely added by js/jquery plugin.
If you want to overwrite other class css properties, either use !important in your class or use deeper dom traversing like #camera.camera-wrap{}. Than this will be given higher priority. Try which works for you.
