React fill SideNavBar from top to bottom with other components on the page

I want my sidenavbar to continue over the whole page but when i add the other
sections(home, contact & projects) which are just regular functional components
with a div and h1, they create their own space on the page. is there a better
solution to creating different sections on a page? i have tried rendering the components
from index and app.js but without success, i am currently rendering SidenavBar
from index.js and my sections are getting rendered from app.js.
import React from "react";
import "../Section.css";
function HomeSection() {
return (
<div className="Section" id="Home">
HomeSection
<h1>Home</h1>
</div>
);
}
export default HomeSection;
here is an example of the sections, the section.css only centers the text on the page.
function SideNavBar() {
const [titleActive, setTitleActive] = useState(HomeSection);
return (
<div className="SideNavBar">
<Stickybox>
<ul className="SideBarList">
{SideBarInfo.map((info, key) => {
return (
<li
key={key}
className="rad"
onClick={() => {
console.log(info.title + " clicked");
setTitleActive(info.title);
}}
id={titleActive === info.title ? "active" : ""}
>
<Link
onClick={() => {
console.log(info.title + " clicked");
setTitleActive(info.title);
}}
id={titleActive === info.title ? "active" : ""}
activeClass="active"
to={info.title}
spy={true}
smooth={true}
offset={50}
duration={500}
>
<div id="title">{info.title}</div>
/Link>
<Link
activeClass="active"
to={info.title}
spy={true}
smooth={true}
offset={50}
duration={500}
>
<div id="bild">{info.bild}</div>
</Link>
</li>
);
})}
</ul>
</Stickybox>
</div>
);
}
export default SideNavBar;
// this is the css for sidebar
.SideNavBar {
width: 250px;
min-height: 5000px;
background-color: rgb(47, 167, 223);
height: 100vh;
}
this is my sidenavbar component.
My sidenavbar works as intended if i remove the sections, i have tried setting a max width and transparent background for the sections so they dont overwrite the sidenavbar but they still overwrite it. what is the correct way to create different sections?
i added a red background for the home section so its easier to see what its doing.

You probably want to do something like this for your sidebar to fix it on the side and have it take up the full screen.
This will fix the sidebar in a position on the screen (0px away from the top and 0px away from the bottom).
You then define the width and you have a fixed sidebar!
Hope that helps!
.sidebar {
top: 0px;
bottom: 0px;
width: 200px;
position: fixed;
background-color: blue;
}
<div class='sidebar'></div>

How can I position button dynamatically according to page components?

In React application I am displaying list of images. When individual book is removed Hide Books button takes the place to that component.
What I am trying to achieve is Hide Books button should remain at the same position and should dynamatically change its position on y axis if whole row of books is deleted
Initial state of application
When individual book is removed -
app.js
return(
<div style={{ position: "relative", minHeight: "100vh" }}>
<button
style={{
position: "absolute",
bottom: "",
}}
onClick={clearBooks}
>
Hide Books
</button>
</div>
)

could you share more of your code? maybe have a codesandox example? It seems to be a styling issue but it's hard to tell without more code.
-edit-
your button should be separated from your list of books, this is the reason why it essentially "follows" your last book card.
Try to do something like this
return (
<section className='wrapper'>
<div className='bookList'>
{booksData.map(book => {
//code your books here
}
</div>
//then put your button out of the div
<button onClick={function}>hide books</button>
</section>
)
your CSS for the wrapper div could be something like this
.wrapper{
display: flex;
flex-direction: column
}
this way you'll have the books first then the button will be displayed below the list

Place the button as the next sibling to the section of Books. Shown in the following. All I did was to move the button out of the section. You will have to style the button with padding and such for the updated layout.
// in index.js, BookList
return (
<>
<section className="booklist">
{booksData.map((book, index) => {
return (
<Book
key={index}
{...book}
removeIndividualBook={removeIndividualBook}
></Book>
);
})}
</section>
{booksData.length === 0 ? (
<button onClick={handleShowBook}>Show Books</button>
) : (
<div style={{ position: "relative", minHeight: "100vh" }}>
<button
style={{
// position: "absolute",
// marginTop: "2350px",
// marginLeft: "28px",
position: "absolute",
//left: "12%",
bottom: "",
}}
onClick={clearBooks}
>
Hide Books
</button>
</div>
)}
</>
);

How to put one div onto another with transition?

I want to create something such that, depending on the state, a given div appears overlapping another div from the right side, here is my code:
const [loggedIn, setLoggedIn] = useState<boolean>(false);
const [hasConfirmedAccount, setHasConfirmedAccount] = useState<boolean>(false);
return (
<>
<div style={{ width: "100%" }}>
<div style={{ float: "left", width: "50%" }}>
<div
style={{ width: "100%", height: "100vh", backgroundColor: "#fafafafa" }}
></div>
</div>
<div id='notLoggedIn' style={{ float: "right", width: "50%" }}>
{!loggedIn && (
<div>
WHEN LOGGED IN === TRUE
</div>
)}
<div
style={
loggedIn && !hasConfirmedAccount
? { width: "100%", transition: "ease-in-out 5s" }
: { display: "none" }
}
>
<div id="notConfirmedAccount">WHENE LOGGED IN === TRUE AND hasConfirmedAccount === FALSE</div>
</div>
</div>
</div>
</>
);
The code works fine, when loggedIn === true and hasConfirmedAccount === false div with id = notConfirmedAccount has been displayed instead of div with id=notLoggedIn, but displaying this div does not work flowing, I want a slow leaving effect of the div on the right side that would overlap the previous div
can someone tell me what to do this?
thanks for any help!

install animate.css => $ npm install animate.css --save
animate.css
2.import "./animate.css" at top your component or project
3.just put the name of aniamte on className like this pattern in your div
<div className={style.forgot} className='animate__animated animate__fadeInDown'>
also you should control your showing div with state

How to implement react-particles-js with anchor links?

Using react-particles-js
as a background on a React project, I discover that disables the anchor tag, don't know if its my implementation
const App = () => {
return (
<div className="App" style={{ position: "relative", overflow: "hidden" }}>
<div style={{ position: "absolute" }}>
<Particles height="330vh" width="100vw" params={particlesConfig} />
</div>
<Home /> {/*this is the content */}
</div>
);
};
What it happens its that in this component with link like this
<a
href="https://tienda-de-garage.herokuapp.com/"
style={{ textDecoration: "none", color: "black" }}
>
<p>Tienda de Garage</p>
</a>
Don't work.
I wonder if its the implementation, maybe the use of the view port the increase the size of the area to encompass the background but i'm not sure.
here its a live version, with the 1 link not working to show the issue

You need to set interactivity.detectsOn to window (InteractivityDetect.window or "window")
You can see a working sample here
This sample uses react-tsparticles but it's the same as react-particles-js since they share the same core library tsparticles

Adding inline styles to react

Currently I'm using react.js and I'm trying to get two div's to be side by side.
Currently I'm trying to
<div id="sidebar" style = "display:inline-block;" >
<script src="build/sidebar.js"></script>
</div>
<div id="map-canvas" style="display: inline-block; width: 20%; height: 50%; "></div>
with sidebar.js as the where react is stored. This unfortunately doesnt work however as it just moves map-canvas to the side while sidebar isn't to the left of it; its on top. I've tried many various combinations w/ float as well and none of them seem to work
Another option is to edit the sidebar.js code where I currently have
return <div>
<input type="text" value={this.state.searchString} onChange={this.handleChange} placeholder="Type here" />
<ul>
{ libraries.map(function(l){
return <li>{l.name} </li>
}) }
</ul>
</div>;
in which I try doing return <div style ="display: inline-block;">
However, in this case the generated html doesnt show up at all. I'm perplex to what I should try but react seems like it doesnt want to play nice with other div elements.

That's because in React, the style prop takes an object instead of a semicolon-separated string.
<div id="sidebar" style={{display : 'inline-block'}} >
<script src="build/sidebar.js"></script>
</div>
<div id="map-canvas" style={{display: 'inline-block', width: '20%', height: '50%'}}>
</div>
Edit:
So this:
return <div style="display: inline-block;">
Would become this:
return <div style={{display: 'inline-block'}}>

const styles = {
container: {
backgroundColor: '#ff9900',
...
...
textAlign: 'center'
}
}
export default class App extends React.Component {
render() {
return(
<div className="container" style={styles.container}>
// your other codes here...
</div>
);
}
}
