CSS Variables are defined the same way as any other CSS declaration, making them syntactically convenient and easy to remember.

Each variable declaration must begin with a double hyphen (--) followed by the variable name. After the variable name is declared a value can then be assigned to it.

In the example below, we have a variable named --main-header-color with a color value #DADECC assigned to it. Note the double hyphen (--) that is preceding the variable name.

h1 { --main-header-color : #DADECC; }

There are specific naming conventions to keep in mind when declaring variables. The first is that variables are case sensitive, meaning --body-text-color and --Body-Text-Color are two different variables. It is also good practice to avoid using capital letters in variable names to prevent this type of confusion. Additionally, it is common to use hyphen delimited strings such as writing --list-background-color instead of --listBackgroundColor when defining a variable name.

Instructions

1.

In style.css locate the .hero selector ruleset. Above the color property create a variable called --main-header-color. Set the value of --main-header-color to be color: #c1bbbb.

Note that you should not see any visual changes.

2.

Next, add a variable for the text color of each button. Inside the .btn selector ruleset, create a variable called --button-text-color right above the color property. Set the variable’s value to be #a5dce4.

3.

Inside the .artist-description selector ruleset, create a variable called --description-font-size above the font-size property and set its value to be 1rem.
