Unit 6 Website Development - Tutorial 2
2.15 Control image sizes using width: 100% and height: auto
Make images responsive without stretching them.
What You Are Adding
Images should usually be allowed to shrink to fit their container. Width: 100% makes the image use the available width, while height: auto keeps the original proportions.
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.
img {
max-width: 100%;
height: auto;
display: block;
}

The image fits the container and keeps its shape.
