import css file into less file

Question

Can you import  css files into  less files      I m pretty familiar with less and use it for all my development  I regularly use a structure as follows    import  normalize      styles here   import  mixins    import  media-queries    import  print     All imports are other  less files and all works as it should   My current issue is this  I want to import a  css file into  less that references styles used in the  css file as follows    import     style css     small       font-size 60        type       other styles here   The  css file contains a class called  type but when I try to compile the  less file I get the error NameError   type is undefined   Will the  less file not import  css files  only other  less ones     Or am I referencing it wrong

From the LESS website      If you want to import a CSS file  and don   t want LESS to process it    just use the  css extension        import  lib css   The directive will just be left as is  and end up   in the CSS output    As jitbit points out in the comments below  this is really only useful for development purposes  as you wouldn t want to have unnecessary  imports consuming precious bandwidth

If you want your CSS to be copied into the output without being processed  you can use the  inline  directive  e g     import  inline      timepicker jquery ui timepicker css

Try this     import  lib css     From the Official Documentation       You can import both css and less files  Only less files import   statements are processed  css file import statements are kept as they   are  If you want to import a CSS file  and don   t want LESS to process   it  just use the  css extension      Source   http   lesscss org

since 1 5 0 u can use the  inline  keyword   Example   import  inline   not-less-compatible css    You will use this when a CSS file may not be Less compatible  this is because although Less supports most known standards CSS  it does not support comments in some places and does not support all known CSS hacks without modifying the CSS  So you can use this to include the file in the output so that all CSS will be in one file    source  http   lesscss org features  import-directives-feature

Change the file extension of your css file to  less  You don t need to write any LESS in it  all CSS is valid LESS  except of the MS stuff that you have to escape  but that s another issue    Per Fractalf s answer this is fixed in v1 4 0

You can force a file to be interpreted as a particular type by specifying an option  e g     import  css   lib     will output   import  lib     and   import  less   lib css     will import the lib css file and treat it as less  If you specify a file is less and do not include an extension  none will be added

[css] import .css file into .less file
