Sorry if it's a silly question, but in fact I can not see the problem or I did not have this experience well, because I'm a beginner. I'm developing through Dreamweaver CC and my CSS has worked perfectly there, but when I switch to browsers, only the Header comes up with the correct color and size formatting. The other sections are not formatted.
#topo {
background-color: #C4EF25;
margin: 0px;
padding: 0px;
width: 100%;
height: auto;
}
;
#menu {
background-color: #174BF3;
margin: 0px;
padding: 0px;
width:
}
;
#corpo {
background-color: #cccccc;
width: 100%;
height: auto;
clear: both;
/* nao permite outro obj flutuar sob a seção corpo */
}
;
#rodape {
background-color: #FDFC0D;
margin: 0px;
padding: 0px;
}
;
