Getting the Math Right
The article width on Markdawn is exactly 608px. It’s a multiple of 16, the base font size on the web. It’s also exactly 16*2 less than 640px, the standard image width on the web and Instagram.
Matching 608px wide text content with 640px wide image is a little bit tricky, but it gives a nice visual feedback to the reader. The CSS code to do this looks something like this:
.content {
width: 608px;
margin: 0 auto;
}
.content img {
width: 105.25%;
height: auto;
margin: 10px -2.63%;
}
For iPhone we have to recalculate both the content and image widths:
@media (max-width: 320px) {
.content {
width: 90%;
}
.content img {
width: 111.11%;
margin-left: -16px;
margin-right: -16px;
}
}
Get the math right folks, because it hurts without it. I use math to give more vibrancy to Markdawn design, thinking outside of box and placing controls on margins of content area. As a closing argument and also as future reminder: always remember who you are building the product for.
