The style of the link should distinguish different states through pseudo-classes. 1. Use a:link to set the unreached link style, 2. a:visited to set the accessed link, 3. a:hover to set the hover effect, 4. a:active to set the click-time style, 5. a:focus ensures keyboard accessibility, always follow the LVHA order to avoid style conflicts. You can improve usability and accessibility by adding padding, cursor:pointer and retaining or customizing focus outlines. You can also use border-bottom or animation underscore to ensure that the link has a good user experience and accessibility in all states.

Create a new Laravel project and start the service; 2. Generate the model, migration and controller and run the migration; 3. Define the RESTful route in routes/api.php; 4. Implement the addition, deletion, modification and query method in PostController and return the JSON response; 5. Use Postman or curl to test the API function; 6. Optionally add API authentication through Sanctum; finally obtain a clear structure, complete and extensible LaravelRESTAPI, suitable for practical applications.

EloquentORM is Laravel's built-in object relational mapping system. It operates the database through PHP syntax instead of native SQL, making the code more concise and easy to maintain; 1. Each data table corresponds to a model class, and each record exists as a model instance; 2. Adopt active record mode, and the model instance can be saved or updated by itself; 3. Support batch assignment, and the $fillable attribute needs to be defined in the model to ensure security; 4. Provide strong relationship support, such as one-to-one, one-to-many, many-to-many, etc., and you can access the associated data through method calls; 5. Integrated query constructor, where, orderBy and other methods can be called chained to build queries; 6. Support accessors and modifiers, which can format the number when obtaining or setting attributes.

Use FormRequests to extract complex form verification logic from the controller, improving code maintainability and reusability. 1. Creation method: Generate the request class through the Artisan command make:request; 2. Definition rules: Set field verification logic in the rules() method; 3. Controller use: directly receive requests with this class as a parameter, and Laravel automatically verify; 4. Authorization judgment: Control user permissions through the authorize() method; 5. Dynamic adjustment rules: dynamically return different verification rules according to the request content.

To achieve CSS element overlap, you need to use positioning and z-index attributes. 1. Use position and z-index: Set elements to non-static positioning (such as absolute, relative, etc.), and control the stacking order through z-index, the larger the value, the higher the value. 2. Common positioning methods: absolute is used for precise layout, relative is used for relatively offset and overlap adjacent elements, fixed or sticky is used for fixed positioning of suspended layers. 3. Actual example: By setting the parent container position:relative, child element position:absolute and different z-index, the card overlap effect can be achieved.

Laravel uses Crypt facade to implement data encryption and decryption. First, ensure that there is a valid APP_KEY in the .env file and generate it through phpartisankey:generate; 1. Use Crypt::encryptString() to encrypt strings, such as $encrypted=Crypt::encryptString('Hello, thisissecret!'); 2. Use Crypt::decryptString($encrypted) to decrypt data, and use try-catch to catch DecryptException exception; 3. In the model, you can use the accessor and
