如何使这个图像响应

HTML:

<section id="first" class="story" data-speed="8" data-type="background">
    <div class="smashinglogo" id="welcomeimg" data-type="sprite" data-offsetY="100" data-Xposition="50%" data-speed="-2"></div>
</section>

CSS:

#first .smashinglogo {background: url(../images/logo1.png)  50% 100px no-repeat fixed;}

在尝试构建maven项目时,我的pom.xml中出现错误.错误在这个插件上:

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version>
        <configuration>
          <source>1.6</source>
          <target>1.6</target>
        </configuration>
      </plugin>

这是Eclipse显示的错误:

Multiple annotations found at this line:
- Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:
 2.3.2:compile (execution: default-compile, phase: compile)

我想查询DNS记录,直到获得正确的域名.

例如,给定www.subdomain.site.com.br,能够从.br挖掘到site.com.br.

实现这一目标的最多(以协议为导向)方式是什么？使用dig/nslookup的配方是最好的.

谢谢.
