<h3>Learn about Rails default layout <code>app/views/layouts/application.html.erb</code>
</h3>
<details><summary>Expand…</summary>- Following the convention over configuration (CoC) principle, Rails uses `application.html.erb` as the default layout to render all pages;
- The original file content in Rails 8 should be the same or similar to:
<pre class="brush:php;toolbar:false"><code>$ cd classless-css-local && code .</code></pre>
<ul>
The upper part of the <li>
<code><head></code> tag contains important structural elements for page rendering and normal operation. The <code><head></code> tag is used to contain metadata and important resources that help configure the page's behavior (using JavaScript), appearance (using CSS), association with other systems and services, and security configuration, such as CSRF and CSP protection; </li>
<li>The main content of the page will be rendered inside <code><body></code> via the ERB tag. This tag serves as an integration point for containing Rails dynamically rendered view content; </li>
</ul>

<p class="Articlelist_txts_p">CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.</p>

<p class="Articlelist_txts_p">The scope of CSS custom properties depends on the context of their declaration, global variables are usually defined in :root, while local variables are defined within a specific selector for componentization and isolation of styles. For example, variables defined in the .card class are only available for elements that match the class and their children. Best practices include: 1. Use: root to define global variables such as topic color; 2. Define local variables inside the component to implement encapsulation; 3. Avoid repeatedly declaring the same variable; 4. Pay attention to the coverage problems that may be caused by selector specificity. Additionally, CSS variables are case sensitive and should be defined before use to avoid errors. If the variable is undefined or the reference fails, the fallback value or default value initial will be used. Debug can be done through the browser developer</p>

<p class="Articlelist_txts_p">Yes, you can use Flexbox in CSSGrid items. The specific approach is to first divide the page structure with Grid and set the subcontainer into a Grid cell as a Flex container to achieve more fine alignment and arrangement; for example, nest a div with display:flex style in HTML; the benefits of doing this include hierarchical layout, easier responsive design, and more friendly component development; it is necessary to note that the display attribute only affects direct child elements, avoids excessive nesting, and considers the compatibility issues of old browsers.</p>
