Input attributes improve form behavior.
    
    ## Example
    ```html
    <input
      type="email"
      placeholder="Email"
      required
    />
    ```
    
    ## Useful attributes
    - required → must fill
    - placeholder → hint text
    - disabled → blocked
    - readonly → visible but not editable
    
    ## Remember
    Attributes guide users without JavaScript.

Control input behavior using required, placeholder, disabled, readonly.
