}
} else {
view! { }
}}
```
### 5. Loading States
```rust
// β Good: Communicate loading states
{move || if is_loading.get() { "Saving..." } else { "Save" }}
// β Avoid: Unclear loading states
{move || if is_loading.get() { "..." } else { "Save" }}
```
## π¨ Common Issues and Solutions
### Issue 1: Missing Focus Indicators
**Problem**: Users can't see which element has focus.
**Solution**:
```rust
// Add focus styles
"Button"
```
### Issue 2: Unclear Button Purposes
**Problem**: Screen readers announce "Button" without context.
**Solution**:
```rust
"Delete"
"This action cannot be undone and will permanently remove your account."
```
### Issue 3: Form Validation Not Announced
**Problem**: Error messages aren't communicated to screen readers.
**Solution**:
```rust
{move || if let Some(error) = validation_error.get() {
view! {
{error}
}
} else {
view! { }
}}
```
### Issue 4: Modal Focus Management
**Problem**: Focus escapes modal and goes to background content.
**Solution**:
```rust
// Implement focus trap
let (modal_ref, set_modal_ref) = signal(None::>);
Effect::new(move |_| {
if let Some(modal) = modal_ref.get() {
// Trap focus within modal
trap_focus(modal);
}
});
```
### Issue 5: Color-Only Information
**Problem**: Information is conveyed only through color.
**Solution**:
```rust
// Add text indicators alongside color
"Active"
```
