This is my PURE CSS solution     Add  scrolling yes to your iframe    lt iframe src  your iframe link  width  100   scrolling  yes  frameborder  0  gt  lt  iframe gt    The trick      lt style gt      html  body  iframe   height  100         html   overflow  hidden     lt  style gt    You don t need to worry about responsiveness

I had this same issue but found the following that works great   The key to creating a responsive YouTube embed is with padding and a container element  which allows you to give it a fixed aspect ratio  You can also use this technique with most other iframe-based embeds  such as slideshows   Here is what a typical YouTube embed code looks like  with fixed width and height     lt iframe width  560  height  315  src    www youtube com embed yCOY82UdFrw    frameborder  0  allowfullscreen gt  lt  iframe gt    It would be nice if we could just give it a 100  width  but it won t work as the height remains fixed  What you need to do is wrap it in a container like so  note the class names and removal of the width and height      lt div class  container  gt    lt iframe src    www youtube com embed yCOY82UdFrw    frameborder  0  allowfullscreen class  video  gt  lt  iframe gt    lt  div gt    And use the following CSS     container       position  relative       width  100        height  0       padding-bottom  56 25        video        position  absolute       top  0       left  0       width  100        height  100        Here is the page I found the solution on   https   www h3xed com web-development how-to-make-a-responsive-100-width-youtube-iframe-embed  Depending on your aspect ratio  you will probably need to adjust the padding-bottom  56 25   to get the height right

You have to use absolute position along with your desired height  in your CSS  do the following    id-of-iFrame       position  absolute      height  100

You should note that div tag behaves like nothing and just let you to put something in it  It means that if you insert a paragraph with 100 lines of text within a div tag  it shows all the text but its height won t change to contain all the text   So you have to use a CSS  amp  HTML trick to handle this issue  This trick is very simple  you must use an empty div tag with class  clear  and then you will have to add this class to your CSS  Also note that your have  wrap in your CSS file but you don t have any tag with this id  In summary you have to change you code to something like below   HTML Code        lt  -- Change  id  from  container  to  wrap  -- gt       lt div id  wrap  gt               lt div id  header  gt           lt  div gt            lt div id  navigation  gt                lt a href     class  navigation  gt home lt  a gt               lt a href  about php  class  navigation  gt about lt  a gt               lt a href  fanlisting php  class  navigation  gt fanlisting lt  a gt               lt a href  reasons php  class  navigation  gt 100 reasons lt  a gt               lt a href  letter php  class  navigation  gt letter lt  a gt           lt  div gt           lt div id  content   gt               lt h1 gt Update Information lt  h1 gt               lt iframe name  frame  id  frame  src  http   website org update php  allowtransparency  true  frameborder  0  gt  lt  iframe gt                lt  -- Add this line -- gt               lt div class  clear  gt  lt  div gt           lt  div gt           lt div id  footer  gt           lt  div gt            lt  -- Add this line -- gt           lt div class  clear  gt  lt  div gt       lt  div gt    And also add this line to your CSS file    clear  display  block  clear  both
