css中的字体样式会产生BOLD结果 - Type style in css is producing BOLD results

我相信这是一个简单的css问题，但我被难住了?-我的H3标签产生粗体文本，我想在正常。页面源不指示<B>标记存在，但文本显然是BOLD。我确实希望我的H2标签是加粗的，但目前没有在css中设置，因为结果已经加粗了。

$FName = $current_user->user_firstname;
$LName = $current_user->user_lastname;
$FullName = $current_user->display_name;

标题标签默认为粗体…重写它。

.normal {
  font-weight:normal;
  }

<h3>DEFAULT</h3>
