YouвЂ™ll notice I also put the inside the anchor tag with a class of hidden вЂ“ this is because the browser wont download an elements background-image if it is not visible on the page.Д¬reating a flashing effect as the slide changes, whilst the browser downloads the image.

the background-repeat to no-repeat so it didnвЂ™t repeat the image in the spaces I want the background-color to fill.ДЄfter that it was just a case of outputting the image as a background-image on the specific slide.

the background-position to 50% 50% so it will be centered horizontally and vertically.

the background-size to contain so that the image will scale down horizontally and vertically.

the background-color for the border when the image is the wrong dimensions.

So punch that into the aspect ratio calculator above and you get: Which worked perfectly and only took me about an hour to implement. So my next attempt was to try using the aspect ratio with a background-image. That worked fine until it went on to mobile.Д«ecause the height needed to respond to the width of the element. The wrapping would then have a background-color that would work as a border for images that donвЂ™t fit the right proportions of the slider. So my initial thought was to use an image with a max width and height, inside a with a set height, styled as a table cell, with the vertical-align set to middle.

I needed to build an image slider that you could upload any sized image in without it looking crap or making the page jump all over the place as the slider does itвЂ™s thing. They are a small company and want their monthly budget to go into work that will make them money (i.e SEO and social media marketing).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).TheyвЂ™re dealing with upwards of 30 companies вЂ“ 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).TheyвЂ™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.Д®xample 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, hereвЂ™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.Д®asy enough but it takes some thinking about. вЂњhвЂќ represents the height of your element and вЂњwвЂќ represents the width.

IвЂ™m always forgetting how to do the equation and it takes energyвЂ¦but hereвЂ™s how it works, if you want to do it manually:

Well you can always use the calculator above вЂ“ thatвЂ™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 itвЂ™s container has a width of 200px.ДЄnd whatвЂ™s so powerful about this, is that when that then scales down to 146px, itвЂ™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 itвЂ™s easy to achieve, but when it comes to iframes, embeds and вЂ™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 вЂњaspect ratioвЂќ is the correlation between the height and width of an element.
