Question

我正在建立一个网站但由于某种原因，我的文字对齐无效。当我输入它时，它对它没有影响。我需要一些帮助。我希望下拉菜单中的内容与左侧对齐。

HTML代码

<!DOCTYPE html>

提前谢谢！

Answer 1

删除

text-align: center;

从这里

#main_navbar li a, #sub_navbar li a {
text-decoration: none;
font-size: 1em;
text-align: center;
color: black;
font-weight: normal;

}

Answer 2

正如@Violetluna所说，从text-align: center;

中移除#main_navbar li a, #sub_navbar li a

#main_navbar li a, #sub_navbar li a {
  text-decoration: none;
  font-size: 1em;
  text-align: center;
  color: black;
  font-weight: normal;
}

您不必将text-align: left;放在上面，因为它是默认属性。

此外，<img>的语法不正确，不是：

<img src="http://i.imgsafe.org/5d32881.png" id="image_symbol"></img>

是：

<img src="http://i.imgsafe.org/5d32881.png" id="image_symbol" />
