Inquiring About Permanent Visibility of Vertical Scrollbar with CSS Overflow: Scroll
When implementing CSS overflow-y: scroll to constrain content within an allotted height, it can be challenging to ensure users notice the presence of additional content. On macOS, Chrome and Safari conceal the vertical scrollbar until the user actively scrolls or hovers over the element. This raises the concern of whether users will immediately recognize that a div contains more content.
A Solution to Force Constant Scrollbar Display
A solution to this issue involves incorporating the following CSS:
::-webkit-scrollbar { -webkit-appearance: none; width: 7px; } ::-webkit-scrollbar-thumb { border-radius: 4px; background-color: rgba(0, 0, 0, .5); box-shadow: 0 0 1px rgba(255, 255, 255, .5); }
This CSS overrides the default styling of scrollbars on macOS browsers. By setting -webkit-appearance to none, the browser's default styling is disabled. The width property specifies the desired width of the scrollbar, and the border-radius property adds a rounded shape to the scroll thumb. The background-color and box-shadow properties provide a custom appearance, enhancing the visibility of the scrollbar.
By integrating this CSS, the vertical scrollbar will remain visible even when the mouse cursor is not hovering over the div, ensuring users clearly see that additional content is available. This solution addresses the challenge posed by macOS's default behavior and improves the user experience by providing a permanent cue indicating scrollable content.

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.

In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
