Explore how to introduce styles in Laravel

Laravel is one of the most popular PHP frameworks today, providing developers with a way to quickly develop modern web applications. Compared to the traditional way of writing PHP, many of Laravel's features are automated, so we can create powerful applications faster. In this article, we will explore how to introduce styles in Laravel.

Using CSS files

In Laravel, we can use traditional CSS files as our stylesheets. Create a css directory under the public directory and place your CSS files in it. For example, if your file is called style.css, your directory structure will look like this:

public/
└── css/
    └── style.css

In order to apply this style sheet to your view, you need to use the HTML link in the view Label. This tag is located in the head (<head>) tag of the view. Assuming your view is located in resources/views/index.blade.php, your code will look like this:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>My Laravel App</title>
    <link rel="stylesheet" href="{{ asset(&#39;css/style.css&#39;) }}">
</head>
<body>
    <!-- your html code here -->
</body>
</html>

Note that in the link tag, we use Laravel's asset helper function to specify the CSS file path of. This method returns the full path to your application URL so they can be loaded in the web page.

Using a CDN

In addition to using local files in your Laravel application, you can also use a CDN (Content Delivery Network) to introduce style sheets. A CDN is a system for delivering network services to improve performance and availability by using servers in multiple geographical locations.

The following is a sample code for introducing Bootstrap's style sheet CDN link in Laravel's view:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>My Laravel App</title>
    <!-- Latest compiled and minified CSS -->
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" 
          integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" 
          crossorigin="anonymous">
</head>
<body>
    <!-- your html code here -->
</body>
</html>

In the above code, we use Bootstrap's CDN to introduce the style sheet. This makes the page load faster and we don't need to worry about whether our server can support the file request.

Using SASS or LESS

Using CSS or CDN links are effective ways to implement stylesheets, but in larger projects you may need more advanced tools to manage them and organize your style sheets.

In this case, you can use SASS or LESS, two popular CSS preprocessors that offer more advanced features like nesting, mixins, and variables.

For SASS or LESS, you need to install the relevant plugin to compile your stylesheet. For SASS, you need to install the laravel/sass package, and for LESS, you need to install the laravel/less package.

For example, if you are using SASS, do the following. Run the following command in the terminal:

composer require laravel/sass

Once this package is installed, you can Create a sass directory. In this sass directory will be your SASS file (.scss). You can then compile your SASS files into CSS files by running the following command:

npm run dev

This command will use Laravel Mix to compile and package your static resource files.

Finally, SASS stylesheets can be used by including the compiled CSS files in the view, as shown in the first part of this article.

Summary

Introducing style sheets into Laravel can use traditional CSS files, CDN links, or use SASS or LESS for CSS preprocessing. We can use HTML's <link> tag or Laravel's Asset tool to introduce CSS files. Whatever method you choose, you should introduce your stylesheets to provide a better user experience. Hope this article is helpful to you, thank you!
