Is it possible to set the equivalent of a src attribute of an img tag in CSS

Question

Is it possible to set the src attribute value in CSS  At present  what I am doing is    lt img src  pathTo myImage jpg   gt    and I want it to be something like this   lt img class  myClass   gt     myClass       some-src-property  url  pathTo myImage jpg      I want to do this without using the background or background-image  properties in CSS

You can define 2 images in your HTML code and use display  none  to decide which one will be visible

Some data I would leave in HTML  but it is better to define the src in CSS    lt img alt  Test Alt text  title  Title text  class  logo  gt    logo       content url     images logo png

Any method based on background or background-image is likely to fail when user prints the document with  print background colors and images  disabled  Which is unfortunately typical browser s default   The only print-friendly and cross-browser compatible method here is the one proposed by Bronx

You can convert it with JS       image-class   each function        var processing     this  attr  src          this  parent   css   background-image   url   processing              this  hide

User · Answer

No you can t set the image src attribute via CSS  The closest you can get is  as you say  background or background-image  I wouldn t recommend doing that anyway as it would be somewhat illogical   However  there is a CSS3 solution available to you  if the browsers you re targeting are able to use it  Use content url as described in Pacerier s answer  You can find other  cross-browser solutions in the other answers below

Or you could do this which I found on the interweb thingy   https   robau wordpress com 2012 04 20 override-image-src-in-css    lt img src  linkToImage jpg  class  egg  gt     egg     width  100     height  0    padding  0 0 200px 0    background-image  url linkToImage jpg     background-size  cover      So effectively hiding the image and padding down the background   Oh what a hack  but if you want an IMG tag with alt text and a background that can scale without using JavaScript   In a project I m working on now I created a hero block twig template   lt div class  hero  gt     lt img class  image  src     bgImageSrc            alt     altText     style  background-image  url    bgImageSrc       gt   lt  div gt

If you are trying to add an image in a button dynamically based on the context of your project  you can use the   take to reference the source based on an outcome   Here I am using mvvm design to let my Model Phases 0  value determine whether I want my button to be populated with images of a lightbulb on or off based on the value of the light phase   Not sure if this helps   I m using JqueryUI  Blueprint  and CSS   The class definition should allow you to style the button based on whatever you d like        lt button gt                                lt img class    Model Phases 0     light-on    light-off    src    Model Phases 0       Images LightBulbOn png       Images LightBulbOff png     gt                                  lt img class    Model Phases 0     light-on    light-off    src    Model Phases 0       Images LightBulbOn png       Images LightBulbOff png     gt        lt img class    Model Phases 0     light-on    light-off    src    Model Phases 0       Images LightBulbOn png       Images LightBulbOff png     gt

There is a solution that I found out today  works in IE6   FF  Opera  Chrome     lt img src  willbehidden png    style  width 0px  height 0px  padding  8px  background  url newimage png    gt    How it works    The image is shrunk until no longer visible by the width  amp  height   Then  you need to  reset  the image size with padding  This one gives a 16x16 image  Of course you can use padding-left   padding-top to make rectangular images  Finally  the new image is put there using background  If the new background image is too large or too small  I recommend using background-size for example  background-size cover  which fits your image into the allotted space     It also works for submit-input-images  they stay clickable   See live demo  http   www audenaerde org csstricks html imagereplacecss  Enjoy

Put several images in a  controlling  container  and change the container s class instead  In CSS  add rules to manage images  visibility depending on the container s class  This will produce the same effect as changing img src property of a a single image   HTML    lt span id  light  class  red  gt       lt img class  red  src  red png    gt       lt img class  yellow  src  yellow png    gt       lt img class  green  src  green png    gt   lt  span gt    CSS    light                  light                    display  none           all images are hidden  light red      red       display  inline         show red image when  light is red  light yellow   yellow    display  inline            or yellow  light green    green     display  inline            or green   Note that it will preload all images  like with CSS backround-images  but unlike changing img src via JS

I know this is a really old question however no answers provide the proper reasoning for why this can never be done   While you can  do  what you are looking for you cannot do it in a valid way   In order to have a valid img tag it must have the src and alt attributes   So any of the answers giving a way to do this with an img tag that does not use the src attribute are promoting use of invalid code   In short  what you are looking for cannot be done legally within the structure of the syntax   Source  W3 Validator

If you don t want to set a background property then you can t set the src attribute of an image using only CSS   Alternatively you can use JavaScript to do such a thing

They are right  IMG is a content element and CSS is about design  But  how about when you use some content elements or properties for design purposes  I have IMG across my web pages that must change if i change the style  the CSS    Well this is a solution for defining IMG presentation  no really the image  in CSS style    create a 1x1 transparent gif or png  Assign propery  src  of IMG to that image  Define final presentation with  background-image  in the CSS style    It works like a charm

Here is a very good solution -  http   css-tricks com replace-the-image-in-an-img-with-css   Pro s  and Con s        works with vector image that have relative width height  a thing that RobAu s answer does not handle       is cross browser  works also for IE8       it only uses CSS  So no need to modify the img src  or if you do not have access do not want to change the already existing img src attribute    -  sorry  it does use the background css attribute
