Ensuring Scroll Bar Visibility for MacOS Trackpad Users in WebKit/Blink
In WebKit/Blink browsers like Safari and Chrome, scroll bars on MacOS have undergone a peculiar behavior since OS X Lion (10.7). When using a trackpad, scroll bars automatically conceal themselves until the user's cursor hovers over the scrollable area. While it may seem like a minimalist touch, this behavior can lead to confusion, especially when the scroll bar serves as the sole indicator of a scrollable element.
Solution: Leveraging WebKit's Pseudo-Elements
To rectify this issue and force scroll bars to remain visible, we can manipulate their appearance through WebKit's -webkit-scrollbar pseudo-elements. By disabling the default appearance and behavior with -webkit-appearance: none, we can take control of the scroll bar's styling and ensure its visibility:
.frame::-webkit-scrollbar {
-webkit-appearance: none;
}
However, since we're overriding the default style, we also need to define the scroll bar's appearance ourselves. The following CSS recreates the semi-transparent hiding scroll bars:
.frame::-webkit-scrollbar:vertical {
width: 11px;
}
.frame::-webkit-scrollbar:horizontal {
height: 11px;
}
.frame::-webkit-scrollbar-thumb {
border-radius: 8px;
border: 2px solid white;
background-color: rgba(0, 0, 0, .5);
}
.frame::-webkit-scrollbar-track {
background-color: #fff;
border-radius: 8px;
}
With these modifications, scroll bars on scrollable elements will remain visible on MacOS, regardless of trackpad usage or cursor position, providing increased clarity and ease of navigation for users.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
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.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
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.
