When you write CSS with confidence, you stop guessing. You stop adding random properties hoping something sticks. Instead, you look at the structure, determine the display type, choose the right layout engine (Flex or Grid), and apply styles that cascade naturally.
In this example, the selector h1 targets all <h1> elements on the web page, while the properties color and font-size define the styles to be applied.

Display: flex. He aligned the items to the center. Padding: 2rem. He gave the text some room to breathe. Border-radius: 8px. He smoothed out the sharp edges of his container.
