To be honest I have avoided using srcset or the picture image because of the complexity and indeed I often find that I have optimised the largest image to a smaller filesize than most people are using in their srcsets anyway and without much loss of quality.

If on the other hand you just want lower or higher quality versions of the exact same image then you use srcset on the img tag and not the picture element. A picture of a forest for desktop but a picture of a single tree on small screen. I think the main thing to consider is that if you want different images then you use the picture element. I would much rather get a crappy image than no content at all. I find that high bandwidth images simply do not load when I have a slow connection. If images have been set with a max-width of 100% then you may also find your images will be squashed because the height will be 250px and the width will be the max-width available and will not match the original aspect ratio. Note that your img-fluid class in bootstrap will be contrary to what you want as that sets the width to 100% and height to auto which is the reverse of what you wanted.Īlso note that by setting the height of the image to 250px it may mean that the image width is massive or tiny unless you have chosen specific aspect ratio images to use and the image may overflow or be too small. The css will then set its width to auto and its height to 250px or whatever you set it to be. It has nothing to do with what you have set up in the html and the image displayed will be the image that was selected in the picture element. It will not make the image fill the width unless it happens to match the width available. That will make the image 250px tall and maintain its aspect ratio. You would then set the image width to auto but not as an attribute in the image tag.

( Edit: Just having looked at caniuse it may be that a few older browsers will recognise srcset but not picture but I wonder if the complexity it adds is worth the price?)Īssuming your images don’t have the same height to begin with then you would need to do this with css preferably and set the image height to the height you want. I am unsure of why you have duplicated the srcet in the img tag as I believed the img tag was a fallback for those that didn’t understand the picture tag or srcset attribute but I guess it may also be a fall back for those that don’t understand the source tag. (I suggest reading that whole article a few times. The media attribute is a directive that the browsers must use if conditions are met.

However srcset and sizes are down to the browsers discretion to choose and if you want full control you would need to use the media attribute on the source tag. You also have width=“auto” which is invalid and will have no effect.

Your code is giving some validator errors anyway and you need the sizes attribute on your source tag when using the format you have. Not just the large seascape made smaller or cropped badly. A large seascape image on desktop may be changed for a small sand-castle on small screens.

It’s not usually used when you just provide lower/higher quality versions of the same image. The picture element is mainly for art-direction in that you deliver different images at various widths/ resolutions. Wow you like making life hard for yourself don’t you That means if somebody has a slow connection he gets the picture with the lowest resolution on his 4x device and thinks i have crappy images on my site? If you write articles the pictures you place in your text can have all kind of different sizes…Īlso i did read that this takes the internet speed into account? What i have in “sizes” is just a placeholder because i don’t get what to put in there. If i don’t do that the picture is stretched over the whole 12 columns.īut non tutorial i did read does set a fixed width or height? I need to take out img-fluid and set width and height. I also made 500H x 360W and 1000H x 720W for 2x and 4x device pixel radio.

The first image is 250H x 180W and that’s the sizes you see on a normal FHD PC Monitor. The second image can have different widths. In this case i want to show two images side by side width the same height.

When Bootstrap 3.2 came out, it came out with an additional helper class to make it easier to make iframes (like YouTube embeds) responsive while maintaining a certain aspect ratio.I have a hard time understanding the sizes on srcset or how to set them. Responsive video embeds that maintain aspect ratio

embed-responsive-item when you want to match the styling for other attributes. Rules are directly applied to, ,, and elements optionally use an explicit descendant class.
