Keeping an Overflow Div Scrolled to the Bottom (Unless the User Scrolls Up)
In certain scenarios, we need a div to automatically scroll to the bottom upon page load and remain there until the user scrolls up. However, when the user scrolls back down, the div should stay at the bottom despite the addition of dynamic content.
Solution with CSS
A clever workaround to achieve this behavior is by using CSS's flex-direction: column-reverse property. This instructs the browser to treat the bottom of the div as the top. As long as the HTML markup is in reverse order, the browser will ensure that the bottom content is always displayed.
Example Code
<code class="css">.container {
height: 100px;
overflow: auto;
display: flex;
flex-direction: column-reverse;
}</code>
<code class="html"><div class="container"> <div>Bottom</div> <div>Hi</div> <!-- More content... --> <div>Top</div> </div></code>
Advantages of this Approach
- Pure CSS solution, no JavaScript required
- Cross-browser compatible
- Supports dynamic content insertion
- Maintains scroll position even after scrolling up

The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.

How can you reduce the payload size of a JavaScript application?
Jun 26, 2025 am 12:54 AM
If JavaScript applications load slowly and have poor performance, the problem is that the payload is too large. Solutions include: 1. Use code splitting (CodeSplitting), split the large bundle into multiple small files through React.lazy() or build tools, and load it as needed to reduce the first download; 2. Remove unused code (TreeShaking), use the ES6 module mechanism to clear "dead code" to ensure that the introduced libraries support this feature; 3. Compress and merge resource files, enable Gzip/Brotli and Terser to compress JS, reasonably merge files and optimize static resources; 4. Replace heavy-duty dependencies and choose lightweight libraries such as day.js and fetch
