HTML

From the beginning, people chose paths through a hyperlinked structure by clicking on links.

 

Later, they interacted with web servers via forms

Links

Makes something clickable
Replaces current page
Can be targeted

<a href="url" target="option">clickable element</a>

A link is a promise: http://www.nngroup.com/articles/link-promise/

Links

URL

  • Relative - the path from current file
  • Absolute - the path from root of site

 

Target

  • _self: Load the response into the same context (default)
  • _blank: Load the response into a new context.

Usability

  • Make links look like links
  • Hint about what will happen
  • Don't distract from current content

Forms

Primary way for getting data from customers

Forms

Most annoying thing about any sales process

Most forms are never completed

Forms

Many form-as-a-service options are available

Ultimately, you need to know how to code them

Basic HTML Forms

Sends data to a server
Replaces the current page

 

Everything is inside a <form> element

Almost everything is an <input> element

Requires a submit button
