How to work with CSS
Each tag in HTML has a corresponding so-called selector CSS. For example, the p tag has a corresponding CSS selector p, with which we can address all paragraphs of an HTML page and, for example, color them all red at once.
After the selector, you should put curly brackets, inside which you should write CSS properties. Properties set the color, font size, and other interesting things. They should be written in this format: the name of the property, then a colon, then the value of this property (for example, the property is the color, and "red" is the value). Then you need to put a semicolon and you can write the next property.
Let's, for example, color all paragraphs red:
p {
color: red;
}
In your styles.css file, place the code that colors paragraphs red. Open your site pages in a browser and make sure that all paragraphs are now red.
