Jan 04, 2025 pm 04:40 PMIf you are starting to develop for the web and your focus is not to specialize in the front-end, one of the barriers that can be most painful is being able to easily style your ugly HTML .
For those who have first contact, it is something enigmatic, mystical, supernatural trying to understand HTML that has a sequence of letters and numbers with predefined utility classes to apply styles to HTML, for example:
<summary class="flex cursor-pointer items-center justify-between rounded-lg px-4 py-2 text-gray-500 hover:bg-gray-100 hover:text-gray-700" >
CSS frameworks that use utility classes are excellent, versatile, responsive, elegant and have many other qualities, but Tailwind CSS is not the only solution. If you need something quick and simpler, using a classless or class-light CSS framework will be a better solution.
Classless CSS Frameworks style HTML elements directly, without classes. Class-light frameworks combine automatic styles with some optional utility classes for customization, which adds greater versatility to their use.
Using a classless or class-light approach you can quickly solve HTML styling with one, two or three lines.
We will see below:
- Use of the Ruby on Rails framework in version 8, with Propshaft and Importmap;
- Getting to know the file with the standard layout of HTML pages;
- Creating and adding content to 4 HTML pages to test styling with CSS;
- A brief mention of the routes created for the pages;
- Change the default layout to include the link to the created pages;
- Add 12 CSS frameworks via CDN to the default layout;
- Know how to identify whether the CSS frameworks have light and dark mode configured by default;
- Suggestions for next steps;
Start a new Rails application
- The time before the rails command is used to display its execution time at the end of the command execution. In the example below, it took 47 seconds.
$ rails -v Rails 8.0.0 $ time rails new classless-css-cdn --skip-test ... real 0m47.500s user 0m33.052s sys 0m4.249s
Rails 8, within its No Build philosophy, will use by default Propshaft as the asset pipeline library and Importmap as the JavaScript library. We ask you to skip the test library with --skip-test.
If necessary, you can process your JavaScript using esbuild by passing the --javascript esbuild parameter. Importmap does not perform any build or any type of processing on JavaScript.

Let's create four pages with HTML content to test the CSS styles.
Ruby on Rails uses the MVC (Model-View-Controller) architecture by default to start organizing your project. Much of your code is organized in the following folders:
- When the code is related to domain/business logic and data, keep it in the app/models folder;
- The code related to the view (HTML, JSON, XML, etc...) will be in app/views;
- Code related to the request lifecycle, will be in app/controllers;

Now yes, stylish HTML?
After saving the stylesheets above and starting the Rails server you will see your HTML styled with the chosen css frameworks.
Dark mode
Some styles have the option for dark mode. To confirm, change your computer's theme in the color customization options. Search in Windows for Enable dark mode for apps and switch between dark or light mode and the HTML page automatically changes after the change in the operating system al.
Next steps
- Organize the styles according to your preference;
- If you want to spend a little more time on the frontend, check out the customization options for your favorite style;
- Dynamically update changes made to the project in the browser using Rails Live Reload;
- Use styling from project CSS files, without using CDN;
- Replicate the capability of classless CSS framework using Tailwind;

There are three ways to create a CSS loading rotator: 1. Use the basic rotator of borders to achieve simple animation through HTML and CSS; 2. Use a custom rotator of multiple points to achieve the jump effect through different delay times; 3. Add a rotator in the button and switch classes through JavaScript to display the loading status. Each approach emphasizes the importance of design details such as color, size, accessibility and performance optimization to enhance the user experience.

To deal with CSS browser compatibility and prefix issues, you need to understand the differences in browser support and use vendor prefixes reasonably. 1. Understand common problems such as Flexbox and Grid support, position:sticky invalid, and animation performance is different; 2. Check CanIuse confirmation feature support status; 3. Correctly use -webkit-, -moz-, -ms-, -o- and other manufacturer prefixes; 4. It is recommended to use Autoprefixer to automatically add prefixes; 5. Install PostCSS and configure browserslist to specify the target browser; 6. Automatically handle compatibility during construction; 7. Modernizr detection features can be used for old projects; 8. No need to pursue consistency of all browsers,

Use the clip-path attribute of CSS to crop elements into custom shapes, such as triangles, circular notches, polygons, etc., without relying on pictures or SVGs. Its advantages include: 1. Supports a variety of basic shapes such as circle, ellipse, polygon, etc.; 2. Responsive adjustment and adaptable to mobile terminals; 3. Easy to animation, and can be combined with hover or JavaScript to achieve dynamic effects; 4. It does not affect the layout flow, and only crops the display area. Common usages are such as circular clip-path:circle (50pxatcenter) and triangle clip-path:polygon (50%0%, 100 0%, 0 0%). Notice

Setting the style of links you have visited can improve the user experience, especially in content-intensive websites to help users navigate better. 1. Use CSS's: visited pseudo-class to define the style of the visited link, such as color changes; 2. Note that the browser only allows modification of some attributes due to privacy restrictions; 3. The color selection should be coordinated with the overall style to avoid abruptness; 4. The mobile terminal may not display this effect, and it is recommended to combine it with other visual prompts such as icon auxiliary logos.

To create responsive images using CSS, it can be mainly achieved through the following methods: 1. Use max-width:100% and height:auto to allow the image to adapt to the container width while maintaining the proportion; 2. Use HTML's srcset and sizes attributes to intelligently load the image sources adapted to different screens; 3. Use object-fit and object-position to control image cropping and focus display. Together, these methods ensure that the images are presented clearly and beautifully on different devices.

The choice of CSS units depends on design requirements and responsive requirements. 1.px is used for fixed size, suitable for precise control but lack of elasticity; 2.em is a relative unit, which is easily caused by the influence of the parent element, while rem is more stable based on the root element and is suitable for global scaling; 3.vw/vh is based on the viewport size, suitable for responsive design, but attention should be paid to the performance under extreme screens; 4. When choosing, it should be determined based on whether responsive adjustments, element hierarchy relationships and viewport dependence. Reasonable use can improve layout flexibility and maintenance.

Different browsers have differences in CSS parsing, resulting in inconsistent display effects, mainly including the default style difference, box model calculation method, Flexbox and Grid layout support level, and inconsistent behavior of certain CSS attributes. 1. The default style processing is inconsistent. The solution is to use CSSReset or Normalize.css to unify the initial style; 2. The box model calculation method of the old version of IE is different. It is recommended to use box-sizing:border-box in a unified manner; 3. Flexbox and Grid perform differently in edge cases or in old versions. More tests and use Autoprefixer; 4. Some CSS attribute behaviors are inconsistent. CanIuse must be consulted and downgraded.
