They have nobody in-house that has Photoshop skills (or Photoshop for that matter).Each banner needs to be sliced to fit the slider (as there is information all over the banners that cannot be cropped off).They’re dealing with upwards of 30 companies – none of whom send through banners the same size.On a monthly basis, companies send them banners promoting offers on their products (i.e Panasonic might send them through a banner that advertises a 2 year warranty).They’re a small company that need to be able to manage the site themselves.I actually come up with this the other day when I was trying to build a slider for a small electronics store. This ones a little more complicated but is very, very useful. Then place your video inside it with absolute positioning.Įxample 2: Image slider (with varying image sizes) You basically create a wrapping that does all the aspect ratio stuff.

This is the most common use of this method and you might not need to even work out the aspect ratio as there are some pretty common sizes (shown in the code below).

So now you understand the core concept, here’s some examples of how to use it with the full CSS. So basically divide the width of your element by 100 and then divide the height of your element by that.Įasy enough but it takes some thinking about. “h” represents the height of your element and “w” represents the width. I’m always forgetting how to do the equation and it takes energy…but here’s how it works, if you want to do it manually: Well you can always use the calculator above – that’s why I made it.
So how do you work out the padding-bottom? Making this super awesome for responsive web design. You have an empty and it’s container has a width of 200px.Īnd what’s so powerful about this, is that when that then scales down to 146px, it’s height will be 73px (which is still in proportion to its width). This is because when you set the padding-bottom as a percentage, it will be worked out as a percentage of the width. So the best way to make elements use an aspect ratio is to set the height to 0 and give the padding bottom as a percentage. Now, with images it’s easy to achieve, but when it comes to iframes, embeds and ’s it can be a little tricky. Think of the way an image scales down its height in proportion to its width in responsive design. The “aspect ratio” is the correlation between the height and width of an element.
