In this video, We experiment with different styles and see their impact on the page. We start with using the * and find out that the changes there will be applied to the whole page. Then, we start making color, style, and text transformation to specific items on the page (like the hr and the table). We see how to apply the background color to yellow for all the bold items on the page, then to specific bold items (the ones in the td within the table). Finally, we covered how we can apply style to an item by referring to its id. And how we can create a class (using dot in front of the name), and reference that class anywhere in the page. If you notice that a specific style is not taking effect, then try to clear the browser cache and reload the page.
