HTML-CSS: Polka dot background pattern
HTML-CSS : Exercise-28 with Solution
Using HTML, CSS creates a polka dot background pattern.
- Use background-color to set a black background.
- Use background-image with two radial-gradient() values to create two dots.
- Use background-size to specify the pattern's size. Use background-position to appropriately place the two gradients.
- Note: The fixed height and width of the element is for demonstration purposes only.

How to get CSS to select ID that begins with a string ?
[id^=product]
^= indicates "starts with". Conversely, $= indicates "ends with".
The symbols are actually borrowed from Regex syntax, where ^ and $ mean "start of string" and "end of string" respectively.
