css - how to combine menubar's code with page 's code? -

I have a PHP page that has a CSS script. I want to place the menu bar on that page. To show the menu bar on that page without disturbing CSS settings on that page? Settings for the menu bar:

  & lt; Style type = "text / css" & gt; .memobar {margin: 0 auto; Padding: 0; } Html {background: #ffffff; } Body {width: 900px; Height: 1000 pixels; Overflow: Auto; Background: #ffffff; } Div # menu {margin: 40px 0 95px; Text-align: center; Status: Completed; } Div # menu span {font-size: 22px; Padding-left: 14px; } Div # copyright (font): 11px 'Trebchett MS'; Color: #fff; Text-align: center; Clear: left; Status: Completed; Top: 546px; Width: 560px; } Div # Copyright One {Color: # 425B7B; } Div # copyright a: hover {color: #fff; } & Lt; / Style & gt;  

Page settings:

  & style; Style = "text / css" & gt; Body {font-family: Times New Roman, Vardana; Font-size: 22px; Width: 900 pixels; Height: 70px; Margin-left: auto; Margin-right: auto; Margin-top: 6px; Background Image: URL ("wood_texture2.jpg"); } & Lt; / Style & gt;  

Change the object name in the menubar's CSS code * Menu bar. For example, in the page css, body means 'apply this style to the page'.

If you change * with * .menubar and

  class = "menubar"  

in the menu bar object, then the menu bar Choose the top style.
