What is the best way to prevent repeating CSS code like this:
div#logo div:nth-child(1) div {
width: 30%;
height: 30%;
background-color: white;
}
div#logo div:nth-child(3) div {
width: 30%;
height: 30%;
background-color: white;
}
If you're looking to style elements in a sequence such as 1,3,5,7....you can use the CSS selector div:nth-child(2n+1). This will start with 2(0)+1=1, then add 2(1)+1=3, 2(2)+1=5, and so on.
div#logo div:nth-child(2n+1) div{
width: 30%;
height: 30%;
background-color: white;
}
To create a cohesive design, you have the option of merging the declarations as shown below:
section#header div:nth-child(2) div, section#header div:nth-child(4) div{
width: 40%;
height: 60%;
background-color: lightgray;
}
style for displaying a white background on every odd colored div within the logo section with dimensions of 30% width and height.
