HTML img scaling

Question

I\'m trying to display some large images with HTML img tags. At the moment they go off the edge of the screen; how can I scale them to stay within the browser window?

<

Answer 1

I think the best solution is resize the images via script or locally and upload them again. Remember, you're forcing your viewers to download larger files than they need

Answer 2

Only set the width or height, and it will scale the other automatically. And yes you can use a percentage.

The first part can be done, but requires JavaScript, so might not work for all users.

Answer 3

No Javascript required.

Percent only works for the width of an element, but height:100%; does not work without the correct code.

CSS

html, body { height:100%; } 

Then using a percentage works properly, and dynamically updates on window resize.

<img src="image.jpg" style="height:80%;">

You do not need a width attribute, the width scales proportionately as the browser window size is changed.

And this little gem, is in case the image is scaled up, it will not look (overly) blocky (it interpolates).

img { -ms-interpolation-mode: bicubic; }

Answer 4

css is enough :

width : desired_width;
height: auto;/*to preserve the aspect ratio of the image*/

Answer 5

I know that this question has been asked for a long time but as of today one simple answer is:

<img src="image.png" style="width: 55vw; min-width: 330px;" />

The use of vw in here tells that the width is relative to 55% of the width of the viewport.

All the major browsers nowadays support this.

Adding max-width: 100%; to the img tag works for me.
