Unit 6 Website Development - Tutorial 2
2.14 Use box-sizing: border-box
Make sizing easier when padding and borders are added.
What You Are Adding
By default, width only controls the content area. Padding and border can make the final box wider than expected. Box-sizing: border-box tells the browser to include padding and border inside the set width.
CSS To Add To css/style.css
Add or adapt this CSS in the stylesheet you created in Tutorial 1. Keep the HTML structure from Tutorial 1 and use CSS to improve the presentation.
* {
box-sizing: border-box;
}
.club-card {
width: 300px;
padding: 20px;
border: 2px solid #365fd0;
}
Expected Output
The width includes the padding and border.
