Certainly! Here's a simple CSS code example that demonstrates how to style a basic HTML element:
```css
/* CSS code */
/* Selecting an HTML element by its tag name */
h1 {
color: #ff0000; /* Sets the text color to red */
font-size: 24px; /* Sets the font size to 24 pixels */
}
/* Selecting an HTML element by its class */
.my-class {
background-color: #f0f0f0; /* Sets the background color to light gray */
padding: 10px; /* Adds 10 pixels of padding around the element */
}
/* Selecting an HTML element by its ID */
#my-id {
border: 1px solid #000000; /* Adds a black border with a width of 1 pixel */
margin-top: 20px; /* Adds a top margin of 20 pixels */
}
/* Selecting multiple HTML elements */
p, li {
font-style: italic; /* Sets the text style to italic */
}
In the above example, we have CSS code that targets different HTML elements using selectors. The `h1` selector targets all `h1` tags and sets the text color to red and the font size to 24 pixels. The `.my-class` selector targets elements with the class name `my-class` and applies a light gray background color and 10 pixels of padding. The `#my-id` selector targets the element with the ID `my-id` and adds a black border with a width of 1 pixel and a top margin of 20 pixels. Lastly, the `p, li` selector targets both `p` tags and `li` tags and sets the text style to italic.
Remember, this is just a basic example to showcase some CSS properties and selectors. You can modify and extend this code to suit your specific needs and apply different styles to various HTML elements on your webpage.
