How to Add Rails Bootstrap?Adding rails with bootstrap is a three-step process; with the capabilities of bootstrap considered individually, the bootstrap can perform this operation in a three-step process; the process involves how the packages correspond to the bootstrap have been added. Next, the process may involve how the added bootstrap through packages can be taken further. Post the packages have been added, the next process is the process of bootstrap gem addition. This is a very critical process. This process will be responsible for opening up the various items associated with a bootstrap. The bootstrap-sass and autoprefixer rails are the two major gems that must be added to the bootstrap application. The process of doing this is explained in the below section. For applying all the opened gems, the bundler has to be executed in the background. The bundler process will be responsible for applying all the gems mentioned in the gem file. The process behind this is explained below,
Below are the bootstrap color comparison patterns and their hexadecimal values for reference; all CSS code that is framed in bootstrap will be performed with the below tabular consideration,

How to Create Rails Bootstrap?The first process to perform when bootstrap has to be added to an application is to use a package manager service such as yarn, npm, and pip to ensure the installation of the bootstrap package. In our case, we have installed using the yarn package manager service, and the command for this process has been shared below,
Command:
yarn add bootstrap jquery @popperjs/coreThe next process involves navigating to the chúng tôi file. In the chúng tôi file, we may need to add the above created or generated bootstrap package to the jquery execution path of the system. For performing this operation, the below-given code has to be added,
Environment.js code addition:
const { environment } = require('@rails/webpacker') const webpack = require("webpack") environment.plugins.append("Provide", new webpack.ProvidePlugin({ $: 'jquery', jQuery: 'jquery', Popper: ['popper.js', 'default'] })) module.exports = environmentGem addition in Gem file:
Running the bundler is the process explained below in the command prompt the bundler has been executed. The bundler command “Blog$ bundle install” is used for unwrapping and executing the bundler. The process behind this is shown in the below-given screenshot. The bootstrap-sass and autoprefixer rails are the two major gems that must be added to the bootstrap application. The process of doing this is explained in the below section. For applying all the opened gems, the bundler has to be executed in the background. The bundler process will be responsible for applying all the gems mentioned in the gem file.
The next segment is to import the bootstrap library, and the @import command is used for importing the bootstrap library. Very importantly, this import must be placed in the chúng tôi file. The chúng tôi file, like an index file of rails applications, must hold the code for first importing the bootstrap library only if the import is fitted well here, then the required sub-packages can be uncovered. From the application packages, which are uncovered, the corresponding packages such as jquery, rails-ujs, turbolinks, and bootstrap-sprockets can be used further in the application. The code for making the import and uncovering the sub-packages in the chúng tôi file is denoted in the below-given snapshot.
Post the creation of the items mentioned above now; the bootstrap must be ready to be connected to the corresponding system
Rails Bootstrap DirectoryThe rails bootstrap directory structure has been provided in the below-given snapshot; the snapshot describes what the bootstrap addition process looks like, and the various folders associated with the bootstrap directory structure can be gained from the below section.

Below, we can see the main Product Sale in the main header, which is in bold and high in text size; the document revision number and Document type as Sample Data are kept in the corner of the Header.
By escaping edit mode from that footer, page numbers will start forming sequentially, which will be created in all the subsequent pages as below.
Also, in Footer, you can enter the Copyright detail or number, and your company’s name, if the format allows you to do so. Below, we have filled the footer with some data.
As you can see in the above screenshot, we have put the company’s name, ABC Corporation, in a light color to make a watermark impression and kept CopyRight Reserved © in small fonts. You can use your format as well.

Install New Apps on Apple TV
On your Apple TV, open the App Store.
Here, you can check out the best apps according to Apple in the ‘Discover’ tab, or head over to any of the other tabs to see apps, games, Apple Arcade games for Apple TV, and more.
Head over to the ‘Search’ icon in the Apple TV.
You can now type to search the app you want, or press and hold the ‘mic’ icon in the Apple TV remote to dictate the app you are searching for. In this example, we will search and install ‘Just Watch’.
Once you’ve typed (or spoken) the name of the app, select it from the results below.
Note: Your Apple TV might ask you to confirm your Apple ID password before downloading the app. You can use your iPhone to enter the password easily. You can also use your iPhone to control your Apple TV as well.
How to Re-download Apps Re-download apps by searching
Open the App Store, and head to the search tab.
Here, search for the app you want to download again. For this example, I will be reinstalling the Prime Video app.
Find purchased apps in the App StoreIf you don’t remember the name of the app you want to reinstall, you can find all your previously used, downloaded, or purchased apps pretty easily. The best part is that if you’ve used the app on a different Apple TV connected to your Apple ID, it will show up on any Apple TVs that are connected with the same Apple ID as well.
Open the App Store, and head to the ‘Purchased’ tab.
Here, you can use the filters on the left of the screen to easily find the app you’re looking for.
Recently Purchased: these are apps you’ve recently downloaded, regardless of whether they are currently installed or not.
Not on This TV: these are the apps that are in your library, but have not been installed.
All Apps: these are all the apps you have ever purchased or downloaded on any Apple TV connected with your Apple ID, regardless of whether they are currently installed or not.
Find the app you want to install by navigating through the ‘Purchased’ section, and open its App Store listing.
That’s it, the app will now be installed on your Apple TV, and you can find it on your home screen.
How to Rearrange Apps on Home Screen in tvOS 15Now that you’ve installed a bunch of your favourite Apple TV apps, your home screen might be looking a little cluttered. Maybe you want to arrange your apps in a particular order by frequency of use, or maybe you simply want to update your top row so your favourite apps can show content suggestions. Either way, here’s how you can rearrange apps on the tvOS 15 home screen.
Select the app you want to move and long press the center button on your Apple TV remote. The app will start jiggling.
You can now move the app around on the home screen and place it wherever you like.

Long press on an app to enter jiggle mode.
Move the app such that it hovers over another app on the home screen. In a second or two, tvOS will create a folder as you can see in the GIF below.
Simply press the center button on the remote to add the app to the folder, and that’s it.
Bonus: Switch Between Open Apps and Force Quit Apps on Apple TV
Double press the TV button on the Apple TV remote. This will open up the recent apps screen on your Apple TV.

You can now swipe through the app cards to switch to a different app.
What’s more, you can select an app in the recents app screen and then swipe up on your Apple TV remote trackpad, and it will quit the app. This is similar to how it works on an iPhone, so it’s quite intuitive.

How To Create Section Counter Using Html And Css?
As websites grow in complexity, it becomes increasingly important for web developers to implement intuitive and user-friendly navigation systems that allow users to easily explore the content on a webpage. One such navigation element that has gained popularity in recent years is called the section counter, which provides users with a clear understanding.
What is a section counter?A section counter in HTML and CSS is a visual element that displays the current section number or position of the user in a webpage, usually displayed in a navigation menu or alongside the section header.
Section counters are helpful for users to keep track of where they are on a webpage, especially if the webpage has many sections or sub sections. With section counters, users can quickly switch to the section they want, and can also see the overall structure of the webpage.
Section counters are usually implemented using CSS counters, which allow web developers to create and manipulate counters for a variety of purposes. By using CSS to style and display the counter, web developers customize the appearance of the counter to fit the design and aesthetics of the website.
Section Counter propertiesTo create a section counter in HTML and CSS, we need the following properties.
counter-reset − The counter-reset property is used to initialize a CSS counter. A counter is a variable that can be incremented or decremented using the counter-increment property, and it is commonly used to keep track of the number of times an element on a webpage.
counter-increment − The counter-increment property is used to increment a CSS counter. We use this property to increase the value of the counter each time a specific element appears on the webpage.
content − The content property is used to specify the content that should be displayed for an element.
Example 1Here is simple example on section counter using HTML and CSS
body { counter-reset: section; background-color:#dee3e0; } h2::before { counter-increment: section; content: “Section ” counter(section) “. “; } Example 2
In the below example, we create an animated section counter with the help of HTML and CSS.
* { box-sizing: border-box; }
/* 4 counters of 25% of screen size*/ .column { float: left; width: 25%; padding: 4px; } .row { margin: 5px; }
/* Style the block*/ .block { padding: 10px; text-align: center; background-color: #bccfc1; color: black; }
/* Styling when mouse will move over the counter*/ .block:hover { transform: scale(1.1); background-color: red; transition-duration: 2s; color: white; } .fa { font-size: 60px; } Conclusion
Creating a section counter using HTML and CSS is a simple way to help visitors navigate the website. By organizing content into sections and using CSS to display the counter, we can make it easier for users to keep track of where they are on the site. With the basic HTML and CSS techniques, we can create a section counter that works for the website and helps improve the user experience.
