Override browser form-filling and input highlighting with HTML CSS

Question

I have 2 basic forms -- sign in and sign up  both on the same page  Now  I have no problem with the sign in form auto-filling  but the sign up form auto fills as well  and I don t like it   Also  the form styles get a yellow background which I can t manage to override and I don t want to use inline CSS to do so  What can I do to make them stop being colored yellow and  possibly  auto filling  Thanks in advance

The REAL problem here is that Webkit  Safari  Chrome       has a bug  When there s more than one  form  on the page  each with an  input type  text  name  foo        i e  with the same value for the attribute  name    then when the user returns to the page the autofill will be done in the input field of the FIRST  form  on the page  not in the  form  that was sent  The second time  the NEXT  form  will be autofilled  and so on  Only  form  with an input text field with the SAME name will be affected   This should be reported to the Webkit developers   Opera autofills the right  form    Firefox and IE doesn t autofill   So  I say again  this is a bug in Webkit

The form element has an autocomplete attribute that you can set to off  As of the CSS the  important directive after a property keeps it from being overriden   background-color  white  important    Only IE6 doesn t understand it   If I misunderstood you  there s also the outline property that you could find useful

Since the browser searches for password type fields  another workaround is to include a hidden field at the beginning of your form    lt  -- unused field to stop browsers from overriding form style -- gt   lt input type  password  style    display none    gt

After trying a lot of things  I found working solutions that nuked the autofilled fields and replaced them with duplicated  Not to loose attached events  i came up with another  a bit lengthy  solution   At each  input  event it swiftly attaches  change  events to all involved inputs  It tests if they have been autofilled  If yes  then dispatch a new text event that will trick the browser to think that the value has been changed by the user  thus allowing to remove the yellow background   var initialFocusedElement   null      inputs      input type  text       var removeAutofillStyle   function       if   this  is   -webkit-autofill          var val   this value          Remove change event  we won t need it until next  input  event        this  off  change            Dispatch a text event on the input field to trick the browser     this focus        event   document createEvent  TextEvent        event initTextEvent  textInput   true  true  window            this dispatchEvent event           Now the value has an asterisk appended  so restore it to the original     this value   val          Always turn focus back to the element that received         input that caused autofill     initialFocusedElement focus            var onChange   function          Testing if element has been autofilled doesn t       work directly on change event    var self   this    setTimeout function         removeAutofillStyle call self        1        inputs on  input   function       if this     document activeElement        initialFocusedElement   this          Autofilling will cause  change  event to be         fired  so look for it      inputs on  change   onChange

I ve read so many threads and try so many pieces of code  After gathering all that stuff  the only way I found to cleanly empty the login and password fields and reset their background to white was the following      window  load function         setTimeout function                input -webkit-autofill                val                  css  -webkit-box-shadow    0 0 0px 1000px white inset                attr  readonly   true               removeAttr  readonly                    50         Feel free to comment  I m opened to all enhancements if you find some

The screenshot you linked to says that WebKit is using the selector input -webkit-autofill for those elements  Have you tried putting this in your CSS   input -webkit-autofill       background-color  white  important      If that doesn t work  then nothing probably will  Those fields are highlighted to alert the user that they have been autofilled with private information  such as the user s home address  and it could be argued that allowing a page to hide that is allowing a security risk

Sometimes autocomplete on the browser still autocompletes when you just have the code in the  lt form gt  element   I tried putting it in the  lt input gt  element as well and it worked better    lt form autocomplete  off  gt   AND   lt input autocomplete  off  gt    Support for this attribute however is ceasing  please read https   bugzilla mozilla org show bug cgi id 956906 c1  https   bugzilla mozilla org show bug cgi id 956906    Another work around that I ve found is taking out placeholders inside of the input fields that suggest that it is an email  username   or phone field  ie   Your Email    Email   etc       This makes it so that browsers don t know what kind of field it is  thus doesn t try to autocomplete it

If it s in input field you re trying to  un-yellow        Set a background-color with css    let s say  ccc  light gray   Add value  sometext   which temporary fills the field with  sometext   optional  Add a little javascript to make the  sometext  clear when you go to put the real text in    So  it might look like this    lt input id  login  style  background-color   ccc   value  username      onblur  if this value      this value  username         onfocus  if this value   username   this value        gt

Please try with autocomplete  none  in your input tag    This works for me

User · Answer

Why not just put this in your css   input --webkit-autocomplete     color  inherit    background  inherit    border  inherit      That should take care of your issue  Although it does raise a usability issue because now the user can t see that the form was autofilled in the way he she is used to    edit  After posting this I saw that a similar answer was already given and that you commented on it that it didn t work  I don t quite see why because it did work when I tested it

Autocomplete off is not supported by modern browsers  The easiest way to solve autocomplete I found was a little track with HTML and JS  The first thing to do is change the type of the input in HTML from  password  to  text     lt input class  input input-xxl input-watery  type  text  name  password   gt    Autocomplete starts after window loaded  That s OK  But when the type of your field is not  password   browser didn t know what fields it must complete  So  there will be no autocomplete on form fields   After that  bind event focusin to password field  for ex  in Backbone    focusin input name password     onInputPasswordFocusIn     In onInputPasswordFocusIn  just change the type of your field to password  by simple check   if  e currentTarget value                 e currentTarget  attr  type    password        That s it    UPD  this thing doesn t work with disabled JavaSciprt  UPD in 2018  Also found some funny trick  Set readonly attribute to the input field  and remove it on the focus event  First prevent browser from autofilling fields  second will allow to input data

You can disable auto-completion as of HTML5  via autocomplete  off    but you CAN T override the browser s highlighting  You could try messing with   selection in CSS  most browsers require a vendor prefix for that to work   but that probably won t help you either   Unless the browser vendor specifically implemented a vendor-specific way of overriding it  you can t do anything about such styles that are already intended to override the site s stylesheet for the user  These are usually applied after your stylesheets are applied and ignore   important overrides  too

You can also change the name attribute of your form elements to be something generated so that the browser won t keep track of it  HOWEVER firefox 2 x  and google chrome seems to not have much problems with that if the request url is identical  Try basically adding a salt request param and a salt field name for the sign-up form   However I think autocomplete  off  is still top solution

After 2 hours of searching it seems Google Chrome still overrides the yellow color somehow  but I found the fix  It will work for hover  focus etc  as well  All you have to do is to add  important to it   input -webkit-autofill  input -webkit-autofill hover  input -webkit-autofill focus  input -webkit-autofill active       -webkit-box-shadow  0 0 0px 1000px white inset  important      this will completely remove yellow color from input fields
