The difference between html front-end and back-end

There are two main ways to implement dark mode: one is to use prefers-color-scheme media to query automatically to adapt system preferences, and the other is to add manual switching function through JavaScript. 1. Use prefers-color-scheme to automatically apply dark themes according to the user system. There is no need for JavaScript, just define the styles in the media query; 2. To achieve manual switching, you need to define light-theme and dark-themeCSS classes, add toggle buttons, and use JavaScript to manage the theme status and localStorage to save user preferences; 3. You can combine both to read localSt first when the page is loaded.

To debug a remote Python application, you need to use debugpy and configure port forwarding and path mapping: First, install debugpy on the remote machine and modify the code to listen to port 5678, forward the remote port to the local area through the SSH tunnel, then configure "AttachtoRemotePython" in VSCode's launch.json and correctly set the localRoot and remoteRoot path mappings. Finally, start the application and connect to the debugger to realize remote breakpoint debugging, variable checking and code stepping. The entire process depends on debugpy, secure port forwarding and precise path matching.

To run Python scripts, you need to configure the build system of SublimeText: 1. Make sure that Python is installed and available on the command line; 2. Create a new build system in SublimeText, enter {"cmd":["python","-u","$file"],"file_regex":"^[]File\"(...?)\",line([0-9]*)","selector":&qu

To create a button's ripple effect, you need to combine HTML, CSS animation and JavaScript; first build a button structure with span elements, set the button style with CSS and hide the overflow content, then create the initial hidden circular ripple element through absolute positioning and rounded corner styles, then define the CSS keyframe animation that expands and fades from the center point, and finally use JavaScript to dynamically add activation classes when clicking to trigger the animation, and calculate the click coordinates to make the ripple diffuse from the click position. The entire process ensures continuous triggering through re-arrangement, and finally achieves an ink ripple interaction effect similar to MaterialDesign.
