Use position:sticky and top:0 to create a sticky head fixed to the top as the page scrolls; 2. For the sticky bottom bar, use position:sticky and bottom:0 to adsorb to the bottom when scrolling to the viewport; 3. If the bottom bar that is always visible, use position:fixed and set bottom:0 and width:100%, while adding margin to the content to avoid occlusion; 4. Ensure that setting z-index prevents hierarchical overlay issues, and note that position:sticky has good compatibility in modern browsers, but it is not supported in older browsers such as IE, and ultimately, it mainly relies on CSS.

First, use the Pattern.compile() method to compile the regular expression into a Pattern object; 2. Then call the matcher() method of the object to create a Matcher instance to match the input string; 3. Use the find() method to find all matches or matches() method to verify the exact match; 4. You can extract the matching content through the group() method or use flags such as CASE_INSENSITIVE to ignore case and other matches; 5. For one-time matching, you can directly use the static Pattern.matches() method to complete. This method is suitable for simple verification, and finally select the appropriate method to complete the pattern matching task according to your needs.

Deadlock cannot be completely avoided, but can be effectively managed through the following measures: 1. Catch deadlock errors in application code (such as MySQL's 1213 error) and retry the transaction. It is recommended to use exponential backoff delay; 2. Shorten the time when the transaction holds locks, move non-database operations out of the transaction and commit as soon as possible; 3. Access tables and rows in a consistent order in all transactions to prevent loop waiting; 4. Use a lower isolation level (such as READCOMMITTED) when allowed to reduce the use of gap locks; 5. Optimize indexes to reduce lock contention, ensure that query conditions, connections and sort fields use appropriate indexes; 6. Use SELECT...FORUPDATE and LOCKINSHAREMODE with caution, lock only necessary rows

Using Bootstrap5's Offcanvas component and responsive grid system, it is easy to create a responsive sidebar that slides out on a small screen and is fixedly displayed on a large screen; 2. Trigger the offcanvas display menu through the "ToggleSidebar" button on mobile devices, and the medium and above screen sidebars are always visible as col-md-3 columns; 3. Optionally add desktop folding function through JavaScript, combined with CSS media query to achieve click shrink into narrow bars and hide text; 4. It is recommended to use icons to optimize compact views, keep navigation concise, avoid unnecessary fixed positioning, and test the response effect through developer tools, and ultimately achieve a smooth user experience with minimal code.

Check the status of the application pool, if it is stopped, start and observe whether it is stopped again; 2. Verify the identity and permissions of the application pool to ensure that the account is correct and has sufficient permissions; 3. View the system and application logs in the event viewer to locate the root cause of the error; 4. Check port conflicts and confirm that the website binding port is not occupied by other processes; 5. Try to recycle or rebuild the application pool to eliminate configuration corruption; 6. Enable failed request tracking to analyze the detailed reasons for the 503 error. The root cause of HTTP error 503 in IIS is usually the application pooling problem, and the above steps can be checked one by one to solve this problem.

Iterrows() provides index and row data (Series format), suitable for simple row traversal but slow performance and does not retain data types; 2. itertuples() returns named tuples, faster and retain data types, and is recommended for high-performance requirements; 3. Manual access through indexing and .loc can provide more flexible control; 4. Prioritize vectorization operations using apply() rather than explicit loops; in short, row iteration is only performed when vectorization cannot be used, and itertuples() is recommended for better performance and type support.

Use HttpURLConnection (built-in in Java, no dependencies): Send GET requests through URL and HttpURLConnection classes, set request methods and header information, read response codes and response bodies, suitable for scenarios without external dependencies, but the code is lengthy and error-prone. 2. Use HttpClient (Java11): A modern HTTP client introduced by Java11 supports smooth syntax and asynchronous requests, configures timeouts and read responses concisely. It is recommended for new projects in Java11 and above. 3. Use ApacheHttpClient (external library): powerful function, suitable for complex scenarios, need to add Maven dependencies, and use Clo

object-fit is a way to control media elements to fill containers. The width and height of the element must be set to take effect. 1.fill will stretch the image and may cause deformation; 2.contain scale to ensure that the full image is displayed but may leave blank; 3.cover scale to scale but may be cropped; 4.none maintains the original size; 5.scale-down selects a smaller scaling method; it is often used in picture and video containers, and adjusts the focus with object-position. It is recommended to use cover or contain in responsive design and test different screen sizes to achieve a consistent layout without distorting content. This property is well supported in modern browsers and can be used safely.
