We use anchor element most of types in document to jump from one document to another. Its good practice to represent link in attentive style
To remove underline from link, text-decoration: none is used in css styling.
#myBtn {
background-color: #0688ef;
color: #fff;
padding: 10px 30px;
text-decoration: none;
border-radius: 5px;
}
<a href="https://www.google.com" id="myBtn" >Click Here</a>
To go specific location in same document, id attribute of that element is used in href with #.
<a href="#top" >Go to Top</a>
