Regarding differences in variable named class selector

[mpsn]

Hi, what's the difference b/t:

.header  img

{

width:200px;

height:220px;

margin-top:-10px;/*we have to overlap and go past the header padding of 10px (see above)*/

border-right:1px solid black;

}

 

compared w/

:

      img.header

    {

        /*etc*/

    }

 

I tried the img.header and the image takes up entire space in my header, whereas .header img{/*stylle info*/}.

 

Any hope appreciatedd

.header img selects any IMG that's a descendant of any class=header element.

 

img.header selects any IMG with a class=header.

 

You need to find yourself a tutorial or book on CSS.
