You can use inline styles to add custome styling to <option> tags.

For eg : <option style="font-weight:bold;color:#09C;">Option 1</option> This will apply the styles to this particular <option> element only.

Then you can use a bit of javascript magic to apply the inline styles to all of the <option> elements within a <select> tag like so :

var select = $(document).getElementById('#select-element-id')

var option = select.children('#option-element-id')

option.css('font-weight', 'bold')

option.css('font-size', '24px')

You can also use <option value="" disabled> <br> </option> to add a line-break between the options.

Leaving here a quick alternative  using class toggle on a table  The behavior is very similar than a select  but can be styled with transition  filters and colors  each children individually    x000D   x000D  function toggleSelect     x000D   if  store classList 0       hidden    x000D      store classList    viewfull  x000D      x000D    else   x000D      store classList    hidden  x000D      x000D    x000D   store   x000D    overflow-y  scroll  x000D    max-height  110px  x000D    max-width  50  x000D     x000D    x000D   hidden   x000D    display  none x000D     x000D    x000D   viewfull   x000D    display  block x000D    x000D   x000D   store  nth-child 4    x000D    background-color  lime  x000D    x000D   x000D  span  font-size 2rem cursor pointer  x000D   lt span onclick  toggleSelect    gt   lt  span gt  x000D    lt div id  store  class  hidden  gt  x000D    x000D   lt ul gt  lt li gt  lt a href   keylogger  gt keylogger lt  a gt  lt  li gt  lt li gt  lt a href   1526269343113  gt 1526269343113 lt  a gt  lt  li gt  lt li gt  lt a href   slow  gt slow lt  a gt  lt  li gt  lt li gt  lt a href   slow2  gt slow2 lt  a gt  lt  li gt  lt li gt  lt a href   Benchmark  gt Benchmark lt  a gt  lt  li gt  lt li gt  lt a href   modal  gt modal lt  a gt  lt  li gt  lt li gt  lt a href   buma  gt buma lt  a gt  lt  li gt  lt li gt  lt a href   1526099371108  gt 1526099371108 lt  a gt  lt  li gt  lt a href   1526099371108o  gt 1526099371108o lt  a gt  lt  li gt  lt li gt  lt a href   pwnClrB  gt pwnClrB lt  a gt  lt  li gt  lt li gt  lt a href   stars 20u  gt stars 20u lt  a gt  lt  li gt  lt li gt  lt a href   pwnClrC  gt pwnClrC lt  a gt  lt  li gt  lt li gt  lt a href   stars   gt stars  lt  a gt  lt  li gt  lt li gt  lt a href   wello  gt wello lt  a gt  lt  li gt  lt li gt  lt a href   equalizer  gt equalizer lt  a gt  lt  li gt  lt li gt  lt a href   pwnClrA  gt pwnClrA lt  a gt  lt  li gt  lt  ul gt  x000D    x000D    lt  div gt  x000D   x000D   x000D

Some properties can be styled for lt option gt  tag    font-family color font-  background-color   Also you can use custom font for individual  lt option gt  tag  for example any google font  Material Icons or other icon fonts from icomoon or alike   That may come handy for font selectors etc    Considering that  you can create font-family stack and insert icons in  lt option gt  tags  eg        lt select gt           lt option style  font-family   Icons    Roboto   sans-serif   gt a        lt  option gt           lt option style  font-family   Icons    Roboto   sans-serif   gt b         lt  option gt       lt  select gt    where   is taken from Icons and the rest is from Roboto   Note though that custom fonts do not work for mobile select

There are only a few style attributes that can be applied to an  lt option gt  element  This is because this type of element is an example of a  quot replaced element quot   They are OS-dependent and are not part of the HTML browser  It cannot be styled via CSS  There are replacement plug-ins libraries that look like a  lt select gt  but are actually composed of regular HTML elements that CAN be styled

Here s some ways to style  lt option gt  along with the  lt select gt  if you re using Bootstrap and or jquery  I understand this isn t what the original poster is asking but I thought I could help others that stumble onto this question   You can still achieve the goal of styling each  lt option gt  separately  but may need to apply some style to the  lt select gt  as well  My favorite is the  Bootstrap Select  library mentioned below     Bootstrap Select Library  jquery   If you re already using bootstrap  you can try the Bootstrap Select library or the library below  since it has a bootstrap theme     Note that you are able to style the entire select element  or the option elements separately   Examples           Dependencies  requires jQuery v1 9 1   Bootstrap  Bootstrap   s dropdown js component  and Bootstrap s CSS  Compatibility  Unsure  but bootstrap says it  supports the latest  stable releases of all major browsers and platforms   Demo  https   developer

You can style the option elements to some extent   Using the   CSS tag you can style the options inside the box that is drawn by the system   Example    ddlProducts      border-radius 15px   background-color red      That will look like this

It s 2017 and it IS possible to target specific select options  In my project I have a table with a class  variations   and the select options are in the table cell td  value   and the select has an ID select pa color  The option element also has a class option  attached   among other class tags   If a user is logged in as a wholesale customer  they can see all of the color options  But retail customers are not allowed to purchase 2 color options  so I ve disabled them   lt option class  attached  disabled gt color 1 lt  option gt   lt option class  attached  disabled gt color 2 lt  option gt    It took a little logic  but here is how I targeted the disabled select options   CSS  table variations td value select pa color option attached disabled   display  none  important      With that  my color options are only visible to wholesale customers
