I often see invalid HTML and cry. I encourage you to read the HTML Spec if you’re curious about valid HTML.
The unordered list element,
only contain zero or more
<template> elements. The
element can contain any element belonging to the flow content category. Some
elements can only specific child elements. You’re encouraged to validate
alt attribute must be specified for every image tag. Here are the
requirements for providing text to act as an alternative for images.
One way to think of alternative text is to think about how you would read the page containing the image to someone over the phone, without mentioning that there is an image present. Whatever you say instead of the image is typically a good start for writing the alternative text.
Below is an example of some valid HTML.
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>My Webpage</title> </head> <body> <h1>Welcome to my webpage</h1> <ul> <li>eggs</li> <li>milk</li> </ul> </body> </html>
