CSS Basics
CSS stands for Cascading Style Sheets. It's used to style the visual presentation of HTML elements.
To apply CSS, you can use the <style> tag in the <head> section of an HTML document, or you can link an external CSS file using the <link> tag.
Selectors
CSS selectors are used to target HTML elements on which to apply styles. Here are some commonly used selectors:
/* Selects all <p> elements */
p {
/* Styles here */
}
/* Selects elements with class "example" */
.example {
/* Styles here */
}
/* Selects elements with id "main-header" */
#main-header {
/* Styles here */
}
Properties
CSS properties define the style of HTML elements. Here are some commonly used properties:
/* Sets the font size to 16 pixels */
font-size: 16px;
/* Sets the text color to blue */
color: blue;
/* Sets the background color to light gray */
background-color: lightgray;
