Expert Answer & Key Takeaways

Mastering HTML Attributes is essential for high-fidelity technical architecture and senior engineering roles in 2026.

HTML Attributes

HTML attributes provide additional information about HTML elements.
  • All HTML elements can have attributes.
  • Attributes provide additional information about an element.
  • Attributes are always specified in the start tag.
  • Attributes usually come in name/value pairs like: name="value".

The href Attribute

The <a> tag defines a hyperlink. The href attribute specifies the URL of the page the link goes to:
<a href="https://www.google.com">Visit Google</a>

The src Attribute

The <img> tag is used to embed an image in an HTML page. The src attribute specifies the path to the image to be displayed:
<img src="img_girl.jpg">

The width and height Attributes

The <img> tag should also contain the width and height attributes, which specify the width and height of the image (in pixels):
<img src="img_girl.jpg" width="500" height="600">

The alt Attribute

The required alt attribute for the <img> tag specifies an alternate text for an image, if the image for some reason cannot be displayed:
<img src="img_girl.jpg" alt="Girl with a jacket">

The style Attribute

The style attribute is used to add styles to an element, such as color, font, size, and more:
<p style="color:red;">This is a red paragraph.</p>

The lang Attribute

You should always include the lang attribute inside the <html> tag, to declare the language of the Web page. This is meant to assist search engines and browsers.
<html lang="en">

The title Attribute

The title attribute defines some extra information about an element. The value of the title attribute will be displayed as a tooltip when you mouse over the element:
<p title="I'm a tooltip">Mouse over me!</p>

💡 Practice Hint

Try adding a title attribute to a paragraph and an alt attribute to an image in your project. It's a small change that makes your site much more professional and accessible!

Interview Corner

❓ Interview Question

Q: Where do HTML attributes always go?
A: Attributes are always specified in the opening (start) tag of an HTML element. They never go in the closing tag.

❓ Interview Question

Q: Are attribute names case-sensitive?
A: No, names like HREF or href mean the same thing. However, lowercase attributes are the industry standard and highly recommended for modern web developers.

❓ Interview Question

Q: Should I always use quotes around attribute values?
A: Yes. While some values work without quotes in HTML5, using double quotes is the best practice. It prevents errors, handles spaces correctly, and is required by many code formatters and stricter standards.
