How to get an attribute value using Selenium WebDriver?

WebElement element = driver.findElement(By.id("myInput"));
String value = element.getAttribute("value");  // Get input field value

WebElement input = driver.findElement(By.name("username"));

// Get input value
String inputValue = input.getAttribute("value");

// Get placeholder text
String placeholder = input.getAttribute("placeholder");

// Get class name
String className = input.getAttribute("class");

// Get id
String id = input.getAttribute("id");

// Check if disabled
String disabled = input.getAttribute("disabled");  // "true" or null

// Get type (text, password, checkbox, etc.)
String type = input.getAttribute("type");

WebElement link = driver.findElement(By.linkText("Home"));
String href = link.getAttribute("href");
System.out.println("Link URL: " + href);

WebElement img = driver.findElement(By.tagName("img"));
String src = img.getAttribute("src");
String alt = img.getAttribute("alt");
System.out.println("Image source: " + src);

WebElement helpIcon = driver.findElement(By.id("helpIcon"));
String tooltip = helpIcon.getAttribute("title");
Assert.assertEquals(tooltip, "Click for help");

// For <div data-user-id="123" data-role="admin">
WebElement card = driver.findElement(By.className("user-card"));
String userId = card.getAttribute("data-user-id");   // "123"
String role = card.getAttribute("data-role");         // "admin"

@Test
public void verifyAttributes() {
    driver.get("https://example.com/form");

    WebElement emailInput = driver.findElement(By.id("email"));

    Assert.assertEquals(emailInput.getAttribute("type"), "email");
    Assert.assertEquals(emailInput.getAttribute("placeholder"), "Enter your email");
    Assert.assertNull(emailInput.getAttribute("disabled"));  // Not disabled
}

// getAttribute — HTML attributes
element.getAttribute("class");   // "btn btn-primary"
element.getAttribute("href");    // "https://example.com"

// getCssValue — CSS style properties
element.getCssValue("color");    // "rgba(255, 0, 0, 1)"
element.getCssValue("font-size"); // "16px"
