I am showing few questions and answer in one webform using DIV and p tag. for example:

<div class="inner">
<h4><span class="blue"> Microsoft</span>RELATED QUESTIONS</h4>

<p class="f1">Q) Who is  Microsoft</p>
<p class="f2">

Microsoft Corporation is an American multinational corporation headquartered in Redmond, Washington, that develops, manufactures, licenses, supports and sells computer software, consumer electronics and personal computers and services. Its best known software products are the Microsoft Windows line of operating systems, Microsoft Office office suite and Internet Explorer web browser. Its flagship hardware products are Xbox game console and the Microsoft Surface series of tablets. It is the world's largest software maker measured by revenues.[4] It is also one of the world's most valuable companies.[5]

Microsoft was founded by Bill Gates and Paul Allen on April 4, 1975 to develop and sell BASIC interpreters for Altair 8800. It rose to dominate the personal computer operating system market with MS-DOS in the mid-1980s, followed by the Microsoft Windows. The company's 1986 initial public offering, and subsequent rise in its share price, created an estimated three billionaires and 12,000 millionaires from Microsoft employees. Since the 1990s, it has increasingly diversified from the operating system market and has made a number of corporate acquisitions.
