点击标签无法正常工作

Question

我有一个简单的网页，没有几个标签，每个标签都有一个段落（或<div> ）。

通过单击这些选项卡，页面应显示相应的段落。 但是，无论我单击哪个选项卡，都会在另一个选项卡下显示所有段落。 例如，如果我单击“联系人”选项卡，它也会在“我是谁”，“法塔赫博客”下显示该段。

[注意：这是在同一页面上显示部分内容的一种很好的做法吗？]

我的代码：

BACKGROUND:
<br /><br />
My name is Jabir Al Fatah and I was born in a small country of South Asia.</b>
I grew up in our sweet little small village. I call the village Green Heaven.
My father was a teacher. I was the fourth child of my parents.

My mother was an ordinary housewife. But she wasn't just an ordinary mother.
She cherished her passion to love and care us. 

I started my elementary school in the nearest village.
At the age of 18 I had to move into Europe. That probably opened a new era for me 
and taught me to turn around. I turned around and that results me what I'm today.

在这行上： <b>LITTLE MORE ABOUT ME:<b>您没有关闭标签。 相反，它应该是<b>LITTLE MORE ABOUT ME:</b>

另外，您应该查看有关<i>和<b>标记的以下链接：

• <i>标签： CSS / HTML：使文本变为斜体的正确方法是什么？
• <b>标签： 不推荐使用的代码：<b> vs style =“ font-weight：bold;”
• <i>和<b>标签： <b>和<strong>，<i>和<em>有什么区别？
