CSS transition effect makes image blurry moves image 1px in Chrome

Question

I have some CSS that on hover  a CSS transition effect will moves a div   The problem  as you can see in the example  is that the translate transition has the horrible side effect of making the image in the div move by 1px down right  and possibly resize ever so slightly   so that it appears out of place and out of focus     The glitch seems to apply the whole time the hover effect is applied  and from a process of trial and error I can safely say only seems to occur when the translate transition moves the div  box shadow and opacity are also applied but make no difference to the error when removed    The problem only seems to happen when the page has scrollbars  So the example with just one instance of the div is fine  but once more identical divs are added and the page therefore requires a scrollbar the problem strikes again

None of this worked  what worked for me is scaling image down  So depending on what size you want the image or what resoultion your image is  you can do something like this   x000D   x000D   ok         transform  perspective 100px  rotateY 0deg  scale 0 5         transition  transform 1s        object-fit contain     ok hover        transform  perspective 100px  rotateY -10deg  scale 0 5         Demo Preview Stuff     bad      max-width  320px     object-fit contain     transform  perspective 100px  rotateY 0deg      transition  transform 1s     bad hover        transform  perspective 100px  rotateY -10deg      div        text-align  center       position  relative       display  flex    h3      position  absolute      bottom  30px      left  0      right  0           b       display  flex    x000D   lt center gt   lt h2 gt Hover on images lt  h2 gt   lt div class  b  gt   lt div gt     lt img class  ok  src  https   www howtogeek com wp-content uploads 2018 10 preview-11 png  gt     lt h3 gt Sharp lt  h3 gt   lt  div gt    lt div gt     lt img class  bad  src  https   www howtogeek com wp-content uploads 2018 10 preview-11 png  gt     lt h3 gt Blurry lt  h3 gt   lt  div gt    lt  div gt    lt  center gt  x000D   x000D   x000D   The image should be scaled down  make sure you have a big image resoultion

2020 update  If you have issues with blurry images  be sure to check answers from below as well  especially the image-rendering CSS property  For best practice accessibility and SEO wise you could replace the background image with an  lt img gt  tag using object-fit CSS property    Original answer Try this in your CSS   your-class-name                     -webkit-backface-visibility  hidden      -webkit-transform  translateZ 0  scale 1  1      What this does is it makes the division to behave  quot more 2D quot    Backface is drawn as a default to allow flipping things with rotate and such  There s no need to that if you only move left  right  up  down  scale or rotate  counter- clockwise  Translate Z-axis to always have a zero value  Chrome now handles backface-visibility and transform without the -webkit- prefix  I currently don t know how this affects other browsers rendering  FF  IE   so use the non-prefixed versions with caution

Just found another reason why an element goes blurry when being transformed  I was using transform  translate3d -5 5px  -18px  0   to re-position an element once it had been loaded in  however that element became blurry   I tried all the suggestions above but it turned out that it was due to me using a decimal value for one of the translate values  Whole numbers don t cause the blur  and the further away I went from the whole number the worse the blur became   i e  5 5px blurs the element the most  5 1px the least    Just thought I d chuck this here in case it helps anybody

You need to apply 3d transform to the element  so it will get its own composite layer  For instance    element      -webkit-transform  translateZ 0       transform  translateZ 0       or   element      -webkit-transform  translate3d 0 0 0       transform  translate3d 0 0 0       More about layer creation criteria you can read right here  Accelerated Rendering in Chrome    An explanation   Examples  hover green box      Problem  Transition may cause blink effect on sibling elements  OSx Lion  Chrome 30    Solution  An element on its own composite layer   When you use any transition on your element it cause browser to recalculate styles  then re-layout your content even if transition property is visual  in my examples it is an opacity  and finaly paint an element     The issue here is re-layout of the content that can make an effect of  dancing  or  blinking  elements on the page while transition happens  If you will go to settings  check  Show composite layers  checkbox and then apply 3d transform to an element  you will see that it gets it s own layer which outlined with orange border     After element gets its own layer  browser just needs to composite layers on transition without re-layout or even paint operations so problem have to be solved

I had a similar problem with blurry text but only the succeeding div was affected  For some reason the next div after the one that I was doing the transform in was blurry  I tried everything that is recommended in this thread but nothing worked  For me rearranging my divs worked  I moved the div that blurres the following div to the end of parents div  If someone know why just let me know   before  lt header class  quot container quot  gt         lt div class  quot transformed div quot  gt             lt span class  quot transform wrapper quot  gt               lt span class  quot transformed quot  gt  lt  span gt               lt span class  quot transformed quot  gt  lt  span gt             lt  span gt          lt  div gt          lt div class  quot affected div quot  gt          lt  div gt        lt  header gt    after  lt header class  quot container quot  gt      lt div class  quot affected div quot  gt      lt  div gt     lt div class  quot transformed div quot  gt         lt span class  quot transform wrapper quot  gt           lt span class  quot transformed quot  gt  lt  span gt           lt span class  quot transformed quot  gt  lt  span gt         lt  span gt      lt  div gt     lt  header gt

For me  now in 2018  The only thing that fixed my problem  a white glitchy-flicker line running through an image on hover  was applying this to my link element holding the image element that has transform  scale 1 05   a      -webkit-backface-visibility  hidden     backface-visibility  hidden     -webkit-transform  translateZ 0  scale 1 0  1 0      transform  translateZ 0  scale 1 0  1 0      -webkit-filter  blur 0      filter  blur 0     a  gt   imageElement      transition  transform 3s ease-in-out
