Supports multiple filter functions such as blur, brightness, contrast, etc. and can be superimposed; 3. It is often used in glass card design, and it is necessary to ensure that the elements overlap with the background; 4. Modern browsers have good support, and @supports can be used to provide downgrade solutions; 5. Avoid excessive blur values and frequent redrawing to optimize performance. This attribute only takes effect when there is content behind the elements.

Create a theme switching component, use the checkbox to bind the isDarkMode state and call the toggleTheme function; 2. Check localStorage and system preferences in onMounted to initialize the theme; 3. Define the applyTheme function to apply the dark-mode class to the html element to switch styles; 4. Use CSS custom properties to define bright and dark variables, and overwrite the default styles through the dark-mode class; 5. Introduce the ThemeSwitcher component into the main application template to display the toggle button; 6. Optionally listen to prefers-color-scheme changes to synchronize the system theme. This solution uses Vue

Create the Modal.vue component, use the Composition API to define the props that receive modelValue and title, and use emit to trigger the update:modelValue event to achieve v-model bidirectional binding; 2. Use slot to distribute content in the template, supporting the default slot and named slot header and footer; 3. Use @click.self to close the pop-up window by clicking the mask layer; 4. Import the Modal in the parent component and use ref to control the display and hide it, and use it in combination with v-model; 5. Optional enhancements include listening to the Escape key close, adding transition animation and focus lock. This modal box component has good

Use hidden check boxes or radio buttons as switches to control the display of content through the :after pseudo-class and sibling selector; 2. Use CSS to hide the input box, style the label to clickable title, and use the checked state to switch the content's max-height to achieve expansion and collapse; 3. Ensure that the label is associated with the input box to improve accessibility, add the :focus style to support keyboard navigation; 4. If you need to expand only one panel at a time, you can use the radio type input box with the same name attribute instead. This method does not require JavaScript, is lightweight and efficient, is suitable for interactive display of static content, and has good accessibility.

Define props in child components, which can be declared and verified using array or object syntax; 2. Pass data to child components through v-bind or its abbreviation in parent components; 3. Support the passing of various data types such as strings, numbers, boolean values, arrays and objects; 4. Comply with props read-only principle, do not directly modify props in child components, but handle them through local data or computed attributes; 5. Use kebab-case to pass props in templates, even if camelCase is used when defining; 6. Always verify the types and necessity of props of reusable components to improve robustness. Using props correctly can ensure predictability and maintainability of communication between components.
