It is recommended to use class names such as float-left and float-right to write styles to external CSS for improved maintainability. Pay attention to using clear:both in subsequent elements to prevent text wrapping, while ensuring that the image is adapted to the screen and test the layout on the mobile side. Although modern layouts use Flexb more frequently

Jul 31, 2025 am 10:34 AMYes, Go's embed feature is very fast because it embeds files directly into binary files at compile time, no disk I/O is required at runtime, data exists in memory as a static asset, and access speeds are close to reading global strings or byte slices. 1. Using the //go:embed directive, the compiler writes the specified file or directory content to a binary file during construction; 2. Access it through the embed.FS type during runtime, and calls the fs.FS interface method (such as ReadFile, Open) to directly read memory without system call overhead; 3. Compared with os.ReadFile and other methods that require disk reading, embed.FS has zero runtime I/O, and has extremely low latency, which is suitable for templates, configurations, front-end resources, etc.
Jul 31, 2025 am 10:34 AMVARCHAR, INT, and DATE are the most commonly used data types in SQL, which are used to store variable-length text, integers, and dates, respectively. VARCHAR is suitable for storing text with unfixed lengths such as names or addresses. When using them, a reasonable length should be set according to actual needs to save space; INT is used to store integers, suitable for counting or identifiers, and appropriate types such as SMALLINT or BIGINT should be selected according to the numerical range; DATE is used to store date values, the format is YYYY-MM-DD. If time information is needed, DATETIME or TIMESTAMP should be used. Correctly selecting the data type can improve database performance and accuracy.
