When you display images on a white background (but also on other colors)\u00a0you’d want to add a border to the image. But adding a ‘normal’ CSS border doesn’t always look very well.<\/p>\n

The solution: semi-transparant borders that are not positioned around<\/strong>, but on<\/strong> the images. This subtle design element will make your galleries look way better. (Facebook, Flickr, Google, … they all use it)<\/p>\n

\"no<\/a>
No border around\/on the images<\/figcaption><\/figure>\n
\"semi-transparent<\/a>
Semi-transparent border on images<\/figcaption><\/figure>\n

Adding this borders can be done very easily using CSS.<\/p>\n

Technique 1: outline<\/h3>\n

A first solution is using the outline<\/code> and outline-offset<\/code> property in CSS:<\/p>\n

img.image {\r\n    outline: 1px solid rgba(0, 0, 0, 0.1);\r\n    outline-offset: -1px;\r\n}<\/code><\/pre>\n
This is very easy and works perfectly in a lot of browsers, but sadly it isn’t supported in Internet Explorer 9 & 10, which have together a market share of over 15% (on the desktop).<\/p>\n
Technique 2: psuedo element<\/h3>\n
Using the :after<\/code> pseudo element has much better browser support. All modern browsers support it.<\/p>\n
div.image-container:after {\r\n    border: 1px solid rgba(0, 0, 0, 0.1);\r\n    content: '';\r\n\r\n    position: absolute;\r\n    top: 0;\r\n    right: 0;\r\n    bottom: 0;\r\n    left: 0;\r\n}<\/code><\/pre>\n
The \u00a0above CSS code will use a pseudo element to position the border right on top\u00a0the image.<\/p>\n
Even though working with the pseudo element is better supported, it can be a bit harder to get it working. People often tend to forget how CSS really works. So mind that the parent div should have position:\u00a0relative<\/code> and that\u00a0:after<\/code> doesn’t work on img<\/code> elements. (Look it up, because explaining all this would lead us way too far from the original topic.)<\/p>\n","protected":false},"excerpt":{"rendered":"
