The HTML structure is as follows. Could you please tell me how to use CSS to select even items of all P elements? Thanks!
<section>
<div class="item">
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit.</p>
</div>
<div class="item">
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit.</p>
</div>
<div class="item">
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit.</p>
</div>
<div class="item">
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit.</p>
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit.</p>
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit.</p>
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit.</p>
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit.</p>
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit.</p>
</div>

you just can use this selector:
.item > p:nth-child(even) {
/* some styles here */
}
.item > p:nth-child(odd) {
/* some styles here */
}
this will select all direct child of .item class and apply your odd or even styles to them, if you want to dismis the direct relationship selection, just use .item p:nth-child(even) { ... }
Set background all P element
p {
background-color:red;
}
Set background all item class
.item{
background-color:red;
}
Set background with id that unique. ID is unique. This can set just one element.
#unique {
background-color:red;
}
Does this answer your question?

First, I apologize for not explaining well.
When I create multiple Accordion using mui(each AccordionDetails height are 80vh). How can I see the entire content of that selected Accordion?
Thank you.
I attached a screenshot for better understanding and code.
SOLUTION
I solved this one using useref and scrollIntoView.
import React, {useState} from 'react';
import Accordion from '#mui/material/Accordion';
import AccordionSummary from '#mui/material/AccordionSummary';
import AccordionDetails from '#mui/material/AccordionDetails';
import Typography from '#mui/material/Typography';
import ExpandMoreIcon from '#mui/icons-material/ExpandMore';
export default function Example() {
const [data, setData] = useState([
{name:"hello",desc:"Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse malesuada lacus ex, sit amet blandit leo lobortis eget."},
{name:"hello",desc:"Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse malesuada lacus ex, sit amet blandit leo lobortis eget."},
{name:"hello",desc:"Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse malesuada lacus ex, sit amet blandit leo lobortis eget."},
{name:"hello",desc:"Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse malesuada lacus ex, sit amet blandit leo lobortis eget."},
])
return (
<div>
{data.map((data) => {
return(
<Accordion>
<AccordionSummary
expandIcon={<ExpandMoreIcon />}
aria-controls="panel1a-content"
id="panel1a-header"
>
<Typography>{data.name}</Typography>
</AccordionSummary>
<AccordionDetails style={{height:"100vh"}}>
<Typography>
{data.desc}
</Typography>
</AccordionDetails>
</Accordion>
)
})}
</div>
);
}

Here's the thing, it all works fine if I run it with the npm run dev script, but images in testimonials.avatar don't render with npm run build.
const Testimonials = ({ testimonials }) => {
return (
<div id='testimonials' className='mt-20'>
<div className='text-center mb-8'>
<p className='text-xs uppercase mb-4 md:text-base'>Testimonials</p>
<h1 className='text-3xl md:text-5xl font-bold capitalize mb-10'>Read What Other<br />have to Say</h1>
</div>
<div className='flex flex-col gap-4 items-center md:flex-row'>
{testimonials.map(item =>
<div className='bg-light-gray rounded-3xl p-8 transition-transform duration-300 hover:-translate-y-2'>
<div className='w-32 h-32 mx-auto mb-4'>
<img src={item.avatar} alt="Person's avatar" className='rounded-full border' />
</div>
<p className='font-bold text-center'>{item.fullName}</p>
<p className='text-center mt-6'>{item.feedback}</p>
</div>
)}
</div>
</div>
)
}
Here I have a component which receives an array testimonials through props and then renders them in a div.
This is the array in App.jsx file.
const testimonials = [
{
avatar: '../src/images/avatars/avatar-1.png',
fullName: 'Andrew Rathore',
feedback: 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc ullamcorper scelerisque mi, in malesuada felis malesuada vel. '
},
{
avatar: '../src/images/avatars/avatar-2.png',
fullName: 'Vera Duncan',
feedback: 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc ullamcorper scelerisque mi, in malesuada felis malesuada vel. '
},
{
avatar: '../src/images/avatars/avatar-3.png',
fullName: 'Mark Smith',
feedback: 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc ullamcorper scelerisque mi, in malesuada felis malesuada vel. '
}
];
I guess I know that the main reason why it does not work while deploying is because of a non-existent path since I will no longer have src/images/avatar during a deploy.
I also guess this is a dumb question because I am quite new to React and JavaScript in general, but would appreciate any answer regarding the problem.
You have to wrap the avatar path in require() like require('../src/images/avatars/avatar-1.png') I hope this works. thanks
Fixed this by creating an external file and then fetching it to the component like so.
data.js
import avatar1 from '../public/images/avatars/avatar-1.png';
import avatar2 from '../public/images/avatars/avatar-2.png';
import avatar3 from '../public/images/avatars/avatar-3.png';
export const testimonials = [
{
authorImg: avatar1,
authorName: 'Andrew Rathore',
authorText: 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc ullamcorper scelerisque mi, in malesuada felis malesuada vel.'
},
{
authorImg: avatar2,
authorName: 'Vera Duncan',
authorText: 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc ullamcorper scelerisque mi, in malesuada felis malesuada vel.'
},
{
authorImg: avatar3,
authorName: 'Mark Smith',
authorText: 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc ullamcorper scelerisque mi, in malesuada felis malesuada vel.'
}
];
Testimonials.jsx
import React from 'react';
import { testimonials } from '../data/data';
const Testimonials = () => {
return (
<div className='flex flex-col gap-4 justify-between items-center md:flex-row'>
{testimonials.map((testimonial, index) =>
<div key={index} className='bg-light-gray rounded-3xl p-8 transition-transform duration-300 hover:-translate-y-2'>
<div className='w-32 h-32 mx-auto mb-4'>
<img src={testimonial.authorImg} alt="Person's avatar" className='rounded-full border' />
</div>
<p className='font-bold text-center'>{testimonial.authorName}</p>
<p className='text-center mt-6'>{testimonial.authorText}</p>
</div>
)}
</div>
)
}
export default Testimonials;
The main reason why it didn't work well in the first place was the fact that I specified path to the images in the object itself like so:
{
key: '../../../value.png'
}
That is why I ran into as error every time while deploying, 'cause it simply couldn't find that path due to its non-existence.
I'm currently trying to fetch some data in my Next.js project using the getStaticProps() function and I continue to get this error:
TypeError: Cannot read property 'map' of undefined
My code looks like this:
export const getStaticProps = async () => {
const data = [
{
"id": 1,
"question": "Lorem ipsum dolor sit amet consectetur adipisicing elit.",
"answer": "Lorem ipsum dolor sit amet consectetur adipisicing elit. Iste magni at magnam placeat. Non, saepe?"
},
{
"id": 2,
"question": "Lorem ipsum dolor sit amet consectetur adipisicing elit.",
"answer": "Lorem ipsum dolor sit amet consectetur adipisicing elit. Iste magni at magnam placeat. Non, saepe?"
}
]
return {
props: {
questions: data
}
}
}
export default function FAQ({ questions }) {
return (
<div className="p-8 grid bg-blanco" >
<div className="grid place-content-center text-center mt-10 md:mt-0" >
<h1 className="text-2xl text-gun-rose-700 font-bold" >¿Tiene preguntas? Mira aquí</h1>
<h3 className="text-gun-rose-300 mt-4 max-w-2xl" >Lorem ipsum dolor sit amet consectetur adipisicing elit. Sunt, suscipit. Aliquid molestias eveniet ullam? Dolores, minus? Perspiciatis neque voluptates iste!</h3>
</div>
{questions.map(q => (
<div className="" key={q.id}>
<h3 className="">{q.question}</h3>
<p className="">{q.answer}</p>
</div>
))}
</div>
)
}
Any guidence will be appreciated, thanks in advance :)
It could be an async issue where questions is not immediately available. Try with a null check at the start of questions.
export default function FAQ({ questions }) {
return (
<div className="p-8 grid bg-blanco" >
<div className="grid place-content-center text-center mt-10 md:mt-0" >
<h1 className="text-2xl text-gun-rose-700 font-bold" >¿Tiene preguntas? Mira aquí</h1>
<h3 className="text-gun-rose-300 mt-4 max-w-2xl" >Lorem ipsum dolor sit amet consectetur adipisicing elit. Sunt, suscipit. Aliquid molestias eveniet ullam? Dolores, minus? Perspiciatis neque voluptates iste!</h3>
</div>
{questions && questions.map(q => (
<div className="" key={q.id}>
<h3 className="">{q.question}</h3>
<p className="">{q.answer}</p>
</div>
))}
</div>
)
}
Edit 1:
The getStaticProps method can only be used on the top level component of a page as stated in the caveats
The fix is to move the getStaticProps method to the top level page component. I've demo'ed this in a sandbox as folder structures are so important, link here.
I want to have more properties in ng-style but it won't work.
This is my code line:
<h3 ng-style="{color: titleColor; font-size: titleSize;}">Lorem ipsum dolor sit amet, consectetuer adipiscing elit.</h3>
If I only have the {color: titleColor} then it works perfectly.
Help me to get the font-size in there aswell
This should work:
<h3 ng-style="{'color': titleColor, 'font-size': titleSize}">Lorem ipsum dolor sit amet, consectetuer adipiscing elit.</h3>
I have used bootstrap plugin to collapse and expand the <div>s. I am able to do it for individual <div>'s but if i leave one <div> expanded and do a collapseAll(), the expanded <div> only getting collapsed. Please provide me a solution on this
html:
<body ng-controller="MainCtrl">
<div class="panel panel-default" ng-repeat="item in items">
<div class="panel-heading" ng-click="isCollapsed = !isCollapsed">{{item.title}}</div>
<div class="panel-body" collapse="isCollapsed">{{item.content}}</div>
</div>
<div>
<input type="checkbox" id="collapse_all_cards" ng-model="isCollapsed"><label for="collapse_all_cards">Collapse All</label>
</div>
</body>
js:
var app = angular.module('plunker', ['ui.bootstrap']);
app.controller('MainCtrl', function($scope) {
$scope.items = [{'title':'Item1','content':'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus maximus orci sodales, pellentesque urna eu'},
{'title':'Item2','content':'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus maximus orci sodales, pellentesque urna eu'},
{'title':'Item3','content':'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus maximus orci sodales, pellentesque urna eu'}
]
});

Please see this Plunk
Pretty sure this is the behavour you are after :)
The problem before was that the same "isCollapsed" property on scope was being used for the "collapse all" and the individual collapses so they were tripping each other up.
See the new controller code which has an individual boolean "isCollapsed" property for each item in the collection:
{'title':'Item1','content':'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus maximus orci sodales, pellentesque urna eu', isCollapsed: true}
If you need any refinements to the code just ask :)
