DEVELOPER FUNdamENTALS:III

doctype says,hey just a heads up a file is going to use HTML5

The senior developers get good salaries and good jobs are the ones fully understand all the meaning behind the things they do

 

HTML tags

10-15 tags are used in 99% time 

<h1></h1> : header 1

it acutally goes all the way up to 6 

<p></p>: paragraph

<b></b>: bold

<ol></ol>: ordered list 

  <li>banban</li>

  <li>apple</li>

<ul></ul>: unordered list 

 

Self Closing HTML tags

<br>: break line 

<hr>: horizonal line 

<img src = "" width="" height="">

src : attribute which had special properties to the specific tag and attribute always has a value attached to 

width:  attribute

height: attribute

 

Anchor tag 

<a href = "newpage.html">New Page </a>

href: attribute and it‘s the hypertext reference 

It can link to other pages 

 

Why named index.html

by default,most servers say :I will return index.html once I see it 

That‘s why we think index.html as our home page 

 

relative path vs absolute path 

relative path 在本地  <a href = "webdevelopment/newpage.html">New Page </a> 转到files://协议

absolute path  在网上 <a href = "www.googe.com">New Page </a>  转到https://协议
