Selenium's Css positioning element

Css positioning elements of Selenium:

The cssSelector positioning belongs to the advanced level of CSS. Its positioning method is carried out by using the selector. In CSS, a selector is a mode for selecting objects that need to be styled. The "CSS" column indicates in which CSS version the property was defined. (CSS1, CSS2 or CSS3.);
A part of CSS positioning methods are listed below. After seeing so many, do you feel that CSS is no longer simple, in fact, the author has marked several commonly used methods, and CSS positioning is a very important method in normal use. It has many similarities with Xpath positioning, but CSS has advantages in terms of performance and syntax.
1. Under normal circumstances, the positioning speed is faster than XPATH
2. The syntax is more concise than Xpath. For

example:

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class elementLocalization {

public static void main(String[] args) {
	
	String chromePath=System.getProperty("user.dir")
			+"\\driver\\chromedriver.exe";
	System.setProperty("webdriver.chrome.driver", chromePath);
	WebDriver driver=new ChromeDriver();
	driver.manage().window().maximize();
	driver.get("https://www.baidu.com");
	try {
		WebElement element=null;   //定义一个Web对象对象
//		element=driver.findElement(By.cssSelector(".s_ipt"));//CSS样式名称定位百度搜索输入框		
		element=driver.findElement(By.cssSelector("#kw"));//CSSID定位百度搜索输入框		
		element=driver.findElement(By.cssSelector("div,a"));//CSS定位所有div对象和a对象
		element=driver.findElement(By.cssSelector("div a"));//CSS定位div标签内所有的a对象		
		element=driver.findElement(By.cssSelector("div>a"));//CSS定位父对象是div的所有a对象
		element=driver.findElement(By.cssSelector("div+a"));//CSS定位紧接在<div> 对象之后的所有<a> 对象		
	    element=driver.findElement(By.cssSelector("[target='_blank']"));//选择target="_blank" 的所有对象。					
	    element=driver.findElement(By.cssSelector("a[name='tj_trnews'][class='mnav']"));//定位A标签中name='tj_trnews'并且class='mnav'的对象				
    	element=driver.findElement(By.cssSelector("a[href^='http']"));//选择a标签对象中href 属性值以"http" 开头的每个<a> 对象。					
	    element=driver.findElement(By.cssSelector("a[href$='.com']"));//选择a标签对象中href属性值以".com"结尾的对象						
	    element=driver.findElement(By.cssSelector("a[href*='news']"));//选择a标签对象中href属性值中包含news的对象		
		element=driver.findElement(By.cssSelector("a:nth-last-child(2)"));//选择属于其父对象的首个<a> 对象的每个<a> 对象。
        element=driver.findElement(By.cssSelector("html body div#wrapper div#head div.head_wrapper div.s_form div.s_form_wrapper.soutu-env-nomac.soutu-env-index form#form.fm span.bg.s_ipt_wr.quickdelete-wrap input#kw.s_ipt"));//通过css绝对路径定位
	} catch (Exception e) {
	    System.out.println("定位失败");
	}
}

}
