The two main parts of a template are the content management code and the theme. These should be kept separate so that the theme can easily be changed without affecting the structure. For example, the styles should be defined in an external style sheet and not embedded in the HTML code of the pages. The structure of a website will be defined by a set of templates. It is good practise to make the templates modular rather than having page templates containing all the code for each page. This allows site-wide changes to be easily applied. For example, the footer may be mostly identical between pages.
These days internet has evolved becoming part of our life. Every successful business and company needs a website. Even individuals need their own sites for interacting with people. However, for attracting customers to site and making the viewers interested one needs to pay importance to web site design. The aesthetics of a site play a great role in ensuring its popularity.
