What is your best asset?(Be HONEST.)

Note:
 All HTML elements can have attributes
 Attributes provide additional information about
elements
 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:
<!DOCTYPE html>
<html>
<body>
<h2>The href Attribute</h2>
<p>HTML links are defined with the a tag. The link address is specified in the href attribute:</p>
<a href="https://www.w3schools.com">Visit W3Schools</a>
</body>
</html>

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:

Example:
<!DOCTYPE html>
<html>
<body>
<h2>The src Attribute</h2>
<p>HTML images are defined with the img tag, and the filename of
the image source is specified in the src attribute:</p>
<img src="img_girl.jpg" width="500" height="600">
</body>
</html>

There are two ways to specify URLs in the src attribute.
1. Absolute URL - Links to an external image that is hosted on another
website. Example: src="https://www.w3schools.com/images/img_girl.jpg".
Notes: External images might be under copyright. If you do not get
permission to use it, you may be in violation of copyright laws. In addition,
you cannot control external images; it can suddenly be removed or
changed.
2. Relative URL - Links to an image that is hosted within the website.
Here, the URL does not include the domain name. If the URL begins
without a slash, it will be relative to the current page. Example:
src="img_girl.jpg". If the URL begins with a slash, it will be relative to the
domain. Example: src="/images/img_girl.jpg".
Tip: It is almost always best to use relative URLs. They will not break if you
change domain.

The width and the height attribute
The <img> tag should also contain the width and height attributes, which
specify the width and height of the image (in pixels):
<!DOCTYPE html>
<html>
<body>
<h2>Width and Height Attributes</h2>
<p>The width and height attributes of the img tag, defines the width and height of
the image:</p>
<img src="img_girl.jpg" width="500" height="600">
</body>
</html>

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. This can be due to a
slow connection, or an error in the src attribute, or if the user uses a screen
reader.
<!DOCTYPE html>
<html>
<body>
<h2>The alt Attribute</h2>
<p>The alt attribute should reflect the image content, so users who
cannot see the image get an understanding of what the image
contains:</p>
<img src="img_girl.jpg" alt="Girl with a jacket" width="500"
height="600">
</body>
</html>

The style attribute
The style attribute is used to add styles to an element, such as color, font, size, and
more.
<!DOCTYPE html>
<html>
<body>
<h2>The style Attribute</h2>
<p>The style attribute is used to add styles to an element, such as
color:</p>
<p style="color:red;">This is a red paragraph.</p>
</body>
</html>

The lang attributes
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.
The following example specifies English as the language:
<!DOCTYPE html>
<html lang="en">
<body>
...
</body>
</html>
Country codes can also be added to the language code in the lang attribute. So, the first
two characters define the language of the HTML page, and the last two characters
define the country.
The following example specifies English as the language and United States as the
country:
<!DOCTYPE html>
<html lang="en-US">
<body>
...
</body>
</html>

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:
Example
<!DOCTYPE html>
<html>
<body>
<h2 title="I'm a header">The title Attribute</h2>
<p title="I'm a tooltip">Mouse over this paragraph, to display the
title attribute as a tooltip.</p>
</body>
</html>
