Interface design

Interface design deals with the process of developing a method for two (or more) modules in a system to connect and communicate. These modules can apply to hardware, software or the interface between a user and a machine. An example of a user interface could include a GUI, a control panel for a nuclear power plant, or even the cockpit of an aircraft.

In systems engineering, all the inputs and outputs of a system, subsystem, and its components are often listed in an interface control document as part of the requirements of the engineering project.

The development of a user interface is a unique field. More information can be found on the subject here: User interface design

CSS and HTML links

What is CSS?

CSS is a Style Sheet Language. CSS stands for Cascading Style Sheet. CSS can format the document content(written in HTML or other markup language): layout, colours, fonts, etc... CSS is designed primarily to enable the separation of the document content and document format. As a result, we can improve content accessibility, can similarly format two or more documents.

HTML Links

Links are found in nearly all Web pages. Links allow users to click their way from page to page.

The HTML <a> tag defines a hyperlink. A hyperlink (or link) is a word, group of words, or image that you can click on to jump to another document. When you move the cursor over a link in a Web page, the arrow will turn into a little hand. The most important attribute of the <a> element is the href attribute, which indicates the link's destination. By default, links will appear as follows in all browsers:

• An unvisited link is underlined and blue
• A visited link is underlined and purple
• An active link is underlined and red

The HTML code for a link is simple. It looks like this:
<a href="url">Link text</a>
The href attribute specifies the destination of a link.
