VTU has recently launched an exciting new subject called “Introduction to Web Programming” (Sub Code: BPLCK105A/205A) exclusively for first-year students. This comprehensive course incorporates an integrated lab component, providing hands-on experience. I am delighted to present the initial version of the lab manual, which includes meticulously crafted solutions and sample outputs for all the lab programs. As we progress, we plan to enrich this manual with additional documentation and algorithms. It is our vision to foster collaboration and knowledge sharing, so we invite anyone to contribute and freely distribute this manual under the Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.
To those who are interested in contributing, we have set up a dedicated platform for collaboration. You can find the repository for the lab manual at https://gitlab.com/lab_manuals/web_22plc15a_repo_vtu_2022_23. This repository serves as a hub for sharing ideas, making improvements, and expanding the content. We welcome your valuable contributions to enhance the learning experience for all. Let’s work together to create a comprehensive resource that benefits the entire community.

<h4>Paragraph</h4>
<p>
<b><i>All that glitters is not gold</i></b> is an aphorism stating that not everything that looks precious or true turns out to be so.
While early expressions of the idea are known from at least the 12th-13th century, the current saying is derived from a 16th-century line by William Shakespeare,
<b><i>All that glisters is not gold</i></b>.
<br /> <br />
<b><i>All that glisters is not gold</i></b><br />
Often have you heard that told.<br />
Many a man his life hath sold<br />
But my outside to behold.<br />
Gilded tombs do worms enfold.<br />
Had you been as wise as bold,<br />
Young in limbs, in judgment old,<br />
Your answer had not been inscrolled<br />
Fare you well. Your suit is cold<br />
-William Shakespeare, Merchant of Venice, Act II Scene 7

<p>
Income, expenses, and profit are financial terms that are used to measure the financial health of a person or a business.
</p>
<p class="income">
Income refers to the amount of money received by an individual or business from various sources such as employment, investments, or sales of goods and services. Income can be earned on a regular basis, such as a salary, or irregularly, such as a bonus or one-time payment.
</p>
<p class="expenses">
Expenses, on the other hand, refer to the amount of money spent by an individual or business to cover their costs of living or operating. Expenses can include fixed costs such as rent or salaries, variable costs such as the cost of materials, or discretionary costs such as entertainment or travel.
</p>
<p class="profit">
Profit is the amount of money that remains after deducting expenses from income. It represents the financial gain or loss that a person or business has generated over a given period of time. A positive profit means that the income was greater than the expenses, while a negative profit means that the expenses were greater than the income.
