Resizing Images Html/css

I have a couple of images in a facebook app. The problem is that the image is quite big and I need it to look well whether it is accessed from a computer or phone. Setting it to so

Solution 1:

Set the width and height on the img tags to be percentages (of their container):

<imgsrc="http://..."alt=""width="50%"height="30%" />

Adjust percentages to your needs.

Solution 2:

Try this

img
 {
    width:100%;/*adjust this value to your needs*/max-width: the size of the image;/* so it wont get bigger and pixelated*/height:auto;
 }

another option if possible, is to use media queries, so for different browser sizes, you can load different size of the image.

here is a fiddle to see if this is what you are trying to achieve
