I am relatively new to using angular material and it has taken a bit more work to use than I have faced using some other css frameworks like PrimeNG, Fomantic/Semantic UI. Most recently I have used PrimeNG which optionally comes with its own suite of utility classes in the form of the primeflex package. It does not appear that material has this (due to them leaving it up to you to decide i suppose) and I am therefore opting to use primeflex WITH angular material components. Is there an existing suite of material css classes that i can use instead, like simple classes that just give flex styles, height: 100%, etc.
My other problem is that I would like to tap into material in order to give my components background/font color styling relative to the current theme but I have not been able to find a 'helper class' that applies the current primary/accent/warn color to an element given the current theme. Any references to documentation are highly appreciated.
I assumed it would look something similar to:
// my-theme.css
#use '#angular/material' as mat;
.my-primary-text-class {
color: mat.$primary-text-color
}
or something similar?

I use ready-made Angular components in my project. Some of the components use colors (see picture) that don't fit my project.
Instead of the purple, I want to use another color. I couldn't find anything in the Angular documentation to change the color.
https://material.angular.io/components/input/overview
I also didn't see a property in Chrome's Inspecter Tool to change the color.
How can I use a different color instead of the purple?
It would be best if you only have to change it in one place, as I use many other Angular components.
If you check the CSS for the placeholder text in the browser inspector, you should see the associated CSS that you should be able to copy to your code and change. Below is what I copied when I went to https://material.angular.io/components/input/overview and inspected (and even changed). If you decided to add this CSS as is to your Angular app, be sure to change the encapsulation option to ViewEncapsulation.None to see the effect. This is if you're using Angular Material v15; otherwise, inspect and see the associated CSS.
.mdc-text-field:not(.mdc-text-field--disabled) .mdc-floating-label {
color: orange;
}
We write css when we use styled components, and I dont understand the benefit of using it why we just dont use the css we write as a classname for the components. In styled components we have wrappers of the components and when we use plain css we have class names. what is the advantage of wrapping components with styled components
The reason styled components is pushed in React web development is to encapsulate styles to only those components. There is no risk of bleeding css into other components. Rather than learn a new css organisation structure new developers can onboard more quickly.
That being said, it is restrictive, slower to develop with, and adds some page weight by applying same styles you could have shared.
I have found the fastest way to work is create static html webpages with pure css, and organise it in a way you are going to import it into your framework. Then you can have boilerplate html designs that can be tested independently of the compiler, which is so much faster to test in Internet Explorer, Firefox, chrome, mobile devices and all the varying screen sizes.
If you want to use styled components, you can either use this npm plugin to convert your static css into variables to use with style components -
https://www.npmjs.com/package/#inspiraller/create-css-vars
or just don't. Nextjs does not support css imports unless its global, so webpack compiling option is a more universal solution.
Main benefits of styled-components are listed in the Motivations page on their website.
styled-components is the result of wondering how we could enhance CSS for styling React component systems. By focusing on a single use case we managed to optimize the experience for developers as well as the output for end users.
Apart from the improved experience for developers, styled-components provides:
Automatic critical CSS: styled-components keeps track of which components are rendered on a page and injects their styles and nothing else, fully automatically. Combined with code splitting, this means your users load the least amount of code necessary.
No class name bugs: styled-components generates unique class names for your styles. You never have to worry about duplication, overlap or misspellings.
Easier deletion of CSS: it can be hard to know whether a class name is used somewhere in your codebase. styled-components makes it obvious, as every bit of styling is tied to a specific component. If the component is unused (which tooling can detect) and gets deleted, all its styles get deleted with it.
Simple dynamic styling: adapting the styling of a component based on its props or a global theme is simple and intuitive without having to manually manage dozens of classes.
Painless maintenance: you never have to hunt across different files to find the styling affecting your component, so maintenance is a piece of cake no matter how big your codebase is.
Automatic vendor prefixing: write your CSS to the current standard and let styled-components handle the rest.
With styled components it's possible to "enhance" CSS classes with JavaScript code because are written in JS.
const Input = styled.input`
color: ${props => props.hasError ? 'red' : 'black'};
`;
Opposed to writing 2 separate CSS classes and control which to show with JS.
.text {
color: black;
}
.text--danger {
color: red;
}
<input className={`text ${hasError ? 'text--danger' : ''}`} />
On the long run it can produce more maintainable code, but it's a matter of personal opinion if it's better to use it or not.
With styled components you can add logic programming
I was playing a little bit with angular materials components. I wanted to know how to overwrite style of angular materials components in scss of component, not in global.scss. And I am wondering why I can overwrite main class of example mat-btn ".mat-raised-button" with different css styles, but for example i can't overwrite main class on mat-tabs ".mat-tab , .mat-tab-header , .mat-ink-bar". I think this is simple question maybe it's about creating content in shadow dom or something but I want some PRO to answer that question :).
For material components like mat-tab, you can use ng-deep in css for styling
For eg:
mat-tab::ng-deep {
// your styles
}
I am working with a freelance client on the side that wants to utilize Angular Material throughout the project. However, they do not like the way that the underline looks in the angular material input. I have tried a variety of approaches to change this, but I haven't found any success yet.
To be honest, I haven't even been able to find the tag in the DOM that would let me alter that border.
Here are the Angular Material docs, as you can see all of the available options have at least some form of a bottom border.
Some approaches I've tried:
This one is from the old angular material and no longer works for the new angular material
The accepted answer here is for the new angular material, but I was not able to get it to work. I implemented exactly as described and no styling changed.
This approach looked like it would work. Unfortunately, I could not get it to work either.
Any help or input on this topic would be appreciated.
For reference, the client said that any changes that deviated from the desired design would be denied. So I have to get this to work. I believe I could maybe, possibly lobby to build a custom input component as a solution, but I know that they are dead set on Angular Material.
Edit. Added a pic of desired look:
this little code did it for me. I didn't want to display it and just set height and width to 0.
::ng-deep .mat-form-field-underline{
height:0 !important;
width:0 !important;
}
However I think its kinda hard to style the Angular Material Components and for me its sometimes better to built my own.
First of all, you'll need a .scss to be imported either within the default theme.scss or after the import of the material stylesheet in main.scss.
Now, Material offers you the option of customising colours and some of the styles by overriding their #mixins found somewhere in the Material folder ( I don't have the folder in front of me.. very sorry for the vague pointing... ).
Back to the newly added file; You can override material's default styling by checking the DOM for certain classes and then adding them in said file with the desired changes. Because the file is loaded after Material's, the default styling in overridden. Same thing applies for the #mixin you chose to override. Just have a look in the file, copy-paste the whole #mixin and change accordingly.
Now if you wish to go even further, my colleagues and I have a custom library that uses Material BUT the whole styling is stripped off leaving you with the bear input within the mat-form-group and then using a <input disabled/> with a position:absolute over it. That way you get to benefit from material without using their style.
I am using Primefaces 5.0.I want to use or bootstrap css to Primefaces custom components like List, table, selectOneListbox.
I am to apply css to normal component like button, link etc.
It's possible, but due to reason that a internal structure of Primefaces's components are different from a plain HTML components with which Bootstrap supposed to work you will need to make hard job to accomplish that. You will need to debug every Primefaces component to see its internal structure and change Bootstrap's css file that it will correspond to internal classes of Primefaces's component.
Actually you have three alternatives (maybe more):
Like BalusC mentioned, Primefaces has its own implementation of Bootstrap theme: you can see it here: http://www.primefaces.org/themes IMHO, best option
Use Bootfaces JSF library: http://www.bootsfaces.net/ Pay attention that it's pretty new library and possible buggy. There isn't big community support like for Primefaces library.
Make you own Composite (or Custom) Components with desired structure and styling.
