CSS Background Color for H1, H2, and H3 Elements
A. h1, h2, h3{background-color:orange;} This is the correct code to set the background color of all h1, h2, and h3 elements to orange. The comma separates the selectors, applying the style to all three elements.
Explanation:
- h1, h2, h3: This is a group selector, targeting all elements with the tag names 'h1', 'h2', and 'h3'.
- background-color:orange;: This property sets the background color of the selected elements to orange.
Incorrect Options:
- B. h1.h2.h3{background-color:orange;}: This code uses class selectors, which are not used to target elements based on their tag names. It wouldn't work as intended.
- C. h1, h2, h3{set-background:orange;}: 'set-background' is not a valid CSS property. The correct property is 'background-color'.
- D. h1 h2 h3{background-color:orange;}: This code uses descendant selectors, which would only apply the style to 'h2' and 'h3' elements that are direct descendants of 'h1' elements. It wouldn't apply to all 'h2' and 'h3' elements on the page.
