    Explanation<\/strong><\/p>\n\n

    Basic Styles<\/em>
    \n The .box class defines small red rectangles with a margin.
    \n The .circle class creates blue circular elements.<\/p>\n\n

    Dynamic Sizing Using :has():
    \n The rule .box:has(+ .circle) applies styles to any .box element that is immediately followed by a .circle.
    \n This rule changes the dimensions of such .box elements to 80px by 80px, making them stand out.<\/p>\n\n

    Visual Output<\/em><\/p>\n\n

    Initially, the boxes are uniform in size.
    \nThe .box element immediately preceding a .circle grows larger due to the :has() rule.<\/p>\n\n
