<p>You wanted the navbar to not to have any white space around it. So I took you code and did some changed to it.</p>

<p>First is the HTML which I removed your <code>&lt;nav&gt;</code> and <code>&lt;ul&gt;</code> then replaced those parts with <code>&lt;div&gt;</code>.</p>

<p>Code:</p>

<pre><code>&lt;body&gt;
&lt;div class="div"&gt;
&lt;div class="sb"&gt;
&lt;input type="text" name="search"&gt;
&lt;input type="submit" name="search" value="search"&gt;
&lt;/div&gt;
&lt;div class="link"&gt;
&lt;a href="www.az.com"&gt;Home |&lt;/a&gt;
&lt;a href="www.az.com/profile"&gt;Profile |&lt;/a&gt;
&lt;a href="www.az.com/settings"&gt;Settings&lt;/a&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;/body&gt;
</code></pre>

<p>After that I took your CSS and made changed to it to fit the query made by you.</p>

<p>Code:</p>

<pre><code>.link{
  margin-left:80%
}
.div{
color:white;
background-color:cyan;
padding-top:19px;
padding-bottom:19px;
padding-right:10px;
height:10%;
}
.sb{
float:left;
margin-left: 2%;
}
body,html{
margin: 0;
padding: 0;
border: 0;
}
</code></pre>

<p>A working fiddle <a href="https://jsfiddle.net/sadaruwan12/kovfh6sf/2/" rel="nofollow noreferrer">Here</a></p>

<p>Now your navbar doesn't have any white space up or right or left. Now it's up to your tinker it to fit your need.</p>


blocks|key|1247326|text|首先，很高兴你想学习HTML和CSS。继续学习，锻炼，永不停止地问！当你也能帮助别人的时候，你也会继续摇摆:)|type|blockquote|depth|inlineStyleRanges|entityRanges|data|1247327|第二，您所面对的是CSS缺省值。至于很多事情，网站需要工作，即使他们没有任何css应用到它。原因是“外部”CSS+(将css文件链接到HTML文件)是在html之后开发的。因此，大多数HTML元素都有默认值，以保证网站不会中断。对于特定示例，body元素也具有默认值：|unstyled|1247328|body+{
++display:+block;
++margin:+8px;+/*+this+is+what+you+do+not+want+*/
}|code-block|syntax|javascript|1247329|css默认值的正式列表-+values.asp|offset|length|1247330|有不同的方法可以消除默认的css值。在今天的web中，更有可能添加一个CSS文件，将所有默认值调整为相同的外观，这就是Normalize.css正在做的事情。更激进的是埃里克·迈尔斯"CSS重置“，它删除了所有默认样式。|1247331|如果您想深入了解这个主题：Normalize.css和重置CSS有什么区别？，我可以高度推荐这个堆栈溢出问题。|1247332|entityMap|0|LINK|mutability|MUTABLE|url|https://www.w3schools.com/cssref/css_default_values.asp|1|https://necolas.github.io/normalize.css/|2|https://meyerweb.com/eric/tools/css/reset/|3|https://stackoverflow.com/questions/6887336/what-is-the-difference-between-normalize-css-and-reset-css^0|0|0|0|D|A|0|0|1N|D|1|2C|E|2|0|D|P|3|0^^$0|@$1|2|3|4|5|6|7|15|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|16|8|@]|9|@]|A|$]]|$1|E|3|F|5|G|7|17|8|@]|9|@]|A|$H|I]]|$1|J|3|K|5|D|7|18|8|@]|9|@$L|19|M|1A|1|1B]]|A|$]]|$1|N|3|O|5|D|7|1C|8|@]|9|@$L|1D|M|1E|1|1F]|$L|1G|M|1H|1|1I]]|A|$]]|$1|P|3|Q|5|D|7|1J|8|@]|9|@$L|1K|M|1L|1|1M]]|A|$]]|$1|R|3|-4|5|D|7|1N|8|@]|9|@]|A|$]]]|S|$T|$5|U|V|W|A|$X|Y]]|Z|$5|U|V|W|A|$X|10]]|11|$5|U|V|W|A|$X|12]]|13|$5|U|V|W|A|$X|14]]]]

<blockquote>
<p>First, great that you want to learn HTML and CSS. Keep learning, exercising and never stop asking! Times will come when you can help others aswell, keep rocking :)</p>
</blockquote>
<p>Second, what you faced are CSS default vales. As for many things websites need to work even if they dont have any css applied to it. The reason for this is that &quot;external&quot; CSS (linking a css file to an html file) was developed years after HTML. Therefore the most HTML elements have default values to guarantee websites dont break. For your specific example the body element has default values too:</p>
<pre><code>body {
  display: block;
  margin: 8px; /* this is what you do not want */
}
</code></pre>
<p>Official list of css default values - <a href="https://www.w3schools.com/cssref/css_default_values.asp" rel="nofollow noreferrer">https://www.w3schools.com/cssref/css_default_values.asp</a></p>
<p>There are different approaches to get rid of default css values. In todays web is more likely to add a CSS file that adjust all default values to the same look, this is what <a href="https://necolas.github.io/normalize.css/" rel="nofollow noreferrer">Normalize.css</a> is doing. The more radical one is <a href="https://meyerweb.com/eric/tools/css/reset/" rel="nofollow noreferrer">Eric Meyers &quot;CSS Reset&quot;</a>, which removes all default styles.</p>
<h3>I can highly recommend this Stack Overflow question if you want to go a bit deeper into this topic: <a href="https://stackoverflow.com/questions/6887336/what-is-the-difference-between-normalize-css-and-reset-css">What is the difference between Normalize.css and Reset CSS?</a></h3>
