“`html
<form id=”contactForm” class=”needs-validation” novalidate>
<div class=”form-group”>
<label for=”name”>Name</label>
<input type=”text” class=”form-control” id=”name” required>
<div class=”invalid-feedback”>Please provide your name.</div>
</div>
<div class=”form-group”>
<label for=”email”>Email</label>
<input type=”email” class=”form-control” id=”email” required>
<div class=”invalid-feedback”>Please provide a valid email.</div>
</div>
<button type=”submit” class=”btn btn-primary”>Submit</button>
</form>
“`
Plus the necessary JavaScript for validation that works right out of the box.
Memory Features That Transform Development
Gemini 2.5 Pro now includes improved memory capabilities, allowing it to remember context throughout an entire development session. This means you can have extended conversations about your project without repeating information.
These memory improvements help with:

This contextual awareness means developers can work more naturally with Gemini, similar to collaborating with a human developer who remembers previous discussions and decisions.
Multimodal Understanding for Better Web Apps
The latest update significantly improves Gemini’s ability to work with multiple types of input. It can now better understand images, videos, text, and code simultaneously, making it more versatile for web development tasks.
With enhanced multimodal capabilities, Gemini can:
- Analyze website designs from images and convert them to code
- Understand UI mockups and generate matching front-end code
- Extract information from screenshots to troubleshoot issues
- Convert hand-drawn wireframes into working prototypes
This multimodal approach helps bridge the gap between design and development, making it easier to turn concepts into functioning web applications.
Real-World Example
Consider Sarah, a front-end developer at a digital marketing agency. She needed to create an interactive product catalog for a client’s website with filtering options, detailed product cards, and a responsive layout—all within a tight deadline.
Instead of spending days writing code from scratch, Sarah used Gemini 2.5 Pro to help. She uploaded the design mockups and described the functionality she needed. Within minutes, Gemini generated the HTML structure, CSS styling, and JavaScript for the interactive elements.
Sarah only needed to make minor adjustments to match the client’s brand guidelines. What would have taken her 3-4 days of coding was completed in just half a day. The client was impressed with both the speed of delivery and the smooth functionality of the catalog on all devices.
“Gemini essentially functioned as my pair programmer,” Sarah explained. “It understood exactly what I needed and generated code that was clean and followed our best practices. The time savings was incredible.”
