The href, src, alt, width, height, style, lang Attribute

The <a> tag defines a hyperlink. The href attribute specifies the URL of the page the link goes to.

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.

The <img> tag should also contain the width and height attributes, which specify the width and height of the image (in pixels).

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.

The style attribute is used to add styles to an element, such as color, font, size, and more.

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.
