In HTML, we can use tag <a href=""> to create hyperlinks between and within pages. The difference is just that, if it's with the prefix '#', it is a link within this page, else it is a link to another page.
link to a web page
This is a link to my blog:
<a href="http://xiang-jiang.blogspot.com/">Xiang-Jiang</a>
It works out like this:
Xiang-Jiang
link within a page
We can use the attribute "id" to create link within a page.
Here is an example:
<a id="bigjump">jump to here</a>
<a href="#bigjump">let's jump</a>
It worked out like this:
jump to here
xxxxxxxxx
let's jump
