CSS - Stupid And Very Simple Css Question... Background Color?

Hi,

I am trying to apply a background color to an item other than the body but I cannot make it display in IE 6 or 5.5. I have tried applying it to both <div>'s and <p>'s. Does IE not support the background-color property outside of the page background?

Hi there people,

I have a question about CSS but before I start off asking this question I'll introduce myself.

I'm a new user of this great forum, my name is Dwight and I'm a student on the "Graphical Lyceum Amsterdam" where I follow the education for "Multimedia Designer".

Ok so now you know me a little, I'll start off asking my question.

Question: I have to change the layout for a html page that askes for information from different asp pages, but that's not my problem . The problem is that I have to make some td's a different color -the background that is- but the problem is that I can't change the html page itself (it is automaticly generated and I don't have permission to change it).
So my question is can someone tell me how I can change the color of some (not all!) td's with CSS without making classes?

Tnx, Dwight

Hey Guys!

I'm going absolutely bonkers trying to find out how to change the color of the background of a certain element on my site. I installed Vanilla forums on my site and am trying to customize the css script.

If you look at the page, you will see an annoying white in the body. I am trying to make the background of that #F6F6F2. Could you guys possibly put me in the right direction?

Thanks!

Having an issue with the background color in a div.

The color shows up in I.E. but not in Firefox.

I have a div with a width of 100%. Inside the div is an unordered list with two list items.

Here is the css:

div#nav {
width: 100%;
margin: 0;
background-color: #EAE9E4;
}

#nav ul {margin: 0; padding: 0; }

#nav li {
list-style: none;
float: left;
margin: 0;
padding: 0;
width: 15%;
font-size: 11px;
line-height: 20px;
white-space: nowrap;
}

Essentially this will be a navigation aid below the banner of the webpage. The list items will contain anchors which will appear as "buttons". The containing div extends to the end and I want it to have a background color.

Any help appreciated.

i wanted usersto choose their own style sheet by giving them different links like red, green, blue which will take them to different layouts or background color page. the problem was that worked only for that particular page but if they click on any link or menu from that page it will take them back to the default color.
is there any way that i can set so that their choice will stay throught their surfing ?
any thoughts ?

I want to display text when I hover over certain areas of an image, so I am using an image map, no href, and assigning the text using ALT=. As a result, the text shows up as a tooltip. It works great except that the background color in the tooltip box is a very dated yellow color that looks inconsistent with the rest of my page. Is there any way to change the background color?

(I am trying to avoid scripts because I've never used them and don't really have time to learn how, at this point)

Thanks, Beth

Take a look at the main menu on this site:
http://www.infund.net

Why doesn't the grey stretch across the entire table? Here's the code I have:

Code:

a.mainlevel:link, a.mainlevel:visited {
	width: 100%;
	background: url(../images/bluebug.png) no-repeat;
	font-family: Trebuchet MS, Verdana, Geneva, Arial, Helvetica, serif;
	font-size: 11px;
	text-align: left;
	padding-left: 30px;
	background-color: #c2c2c2;
	margin-bottom: 1px;
	white-space: nowrap;
	text-align:left;
	}

a.mainlevel:hover, a.mainlevel:hover {
	text-decoration: underline;
	background: url(../images/redbug.png) no-repeat;
	font-family: Trebuchet MS, Verdana, Geneva, Arial, Helvetica, serif;
	vertical-align: middle;
	font-size: 11px;
	font-weight: bold;
	color: #8B1414;
	text-align: left;
	padding-left: 30px;
	background-color: #c2c2c2;
	width: 100%;
	white-space: nowrap;
	margin-bottom: 1px;
	text-align:left;
	}

Hello,

I have been trying to figure this out, but have been unsuccessful. I am using a modalPopupExtender, but when the popup comes up, my background is still active. I suspect it has to be something in my css file, but would appreciate some help on this. I suspect it is the css that is causing this, but cannot figure out what. TIA!

Here is the code for the MPE:

<cc1:ModalPopupExtender ID="MPE1" runat="server"
TargetControlID="btnShowModalPop"
PopupControlID="divPop"
BackgroundCssClass="modalBackground"
PopupDragHandleControlID="panelDragHandle"
DropShadow="true"/>


Here is the code in my css file:

.modalBackground {
background-color:Gray;
filter:alpha(opacity=70);
opacity:0.7;
}

.modalPop {
background-color:Gray;
border-width:3px;
border-style:solid;
border-color:Black;
padding:0;
width:250px;
color:White;



}

.drag
{
background-color:#ff0000;
cursor: move;
border: solid 2px white;



}










I found the issue by referencing a blank css file and slowly adding statements in. It was a combination of the following which prevented the backgroundcssclass to not be shown propertly:

#body div div { background: url(images/body_tr.gif) top right no-repeat; }

#body div div div { background: url(images/body_bl.gif) bottom left no-repeat; }
#body div div div div{ background: url(images/body_br.gif) bottom right no-repeat; }


#body div div div { background: url(images/body_bg.gif) bottom left no-repeat; }
#body div div div div { background: url(images/body_bg.gif) bottom right no-repeat; }


#body .inner div { background: none; }

I ended up add these bg imgs in my master page div tags directly and is working fine.....for now :P

Hi,

I am trying to set background color on hover for a single table of links, rather than the entire document like the below example shows.

http://www.projectseven.com/tutorials/css/pseudoclasses/

I have tried various ways, I do not want to use javascript for this and I am aware of the way to apply background color to the .td field but this also applys to the normal text not just links.

So my question is how do I apply the background hover color to one table of links instead of the body. Thanks!

Hi all,

I haven't been working with CSS that long and I've searched for a fix but couldn't get anything to work. I can't get a background color to display in Firefox but it does in IE. Inside my "mainwrap" I have two columns and for some reason when I set my background to white for the "mainwrap" it just doesn't show up in Firefox.

Thanks for your time!

I've been trying various fixes with my template, so that the grey background color in the sidebar, extends beyond the content to the bottom of the page.

Alas... nothing is working.

Here's my code:

Code:

#l_sidebar { color: #cccccc; background-color: #3a3a3a; width: 160px; float: left; float: left; margin-top: 0; margin-bottom: 20px; padding: 0 15px 15px 15px; }
#l_sidebar p{
        margin: 0px;
	line-height: 16px;
        padding: 0px 0px 5px 0px;
	}
#l_sidebar h2 {
	color: #ffbfea;
	font-size: 18px;
	font-family: Verdana, Helvetica, Arial, Sans-Serif;
	font-weight: bold;
	list-style: none;
	padding: 10px 0px 10px 0px;
        margin: 0px;
	}


#l_sidebar ul {
	list-style: none;
	margin: 0px;
	padding: 0px 0px 20px 0px;
	}
	
#l_sidebar li {
	list-style: none;
	margin: 0px;
	padding: 0px;
	}
	
#l_sidebar ul li {
	list-style: none;
	margin: 0px;
	padding: 6px 0px 5px 0px;
	}
	
#l_sidebar ul li a {
	color: #c04080;
	text-decoration: none;
	}

#l_sidebar ul li a:hover {
	color: #c04080;
	text-decoration: underline;
	}


#r_sidebar { color: #c04080; background-color: #3a3a3a; width: 160px; float: right; position:relative; margin-top: 0; margin-bottom: 20px; padding: 0 15px 15px 15px; }
#r_sidebar p{
        margin: 0px;
	line-height: 16px;
        padding: 5px 0px 10px 0px;
	}
#r_sidebar h2 {
	color: #ffbfea;
	font-size: 18px;
	font-family: Verdana, Helvetica, Arial, Sans-Serif;
	font-weight: bold;
	list-style: none;
	padding: 10px 0px 10px 0px;
        margin: 0px;
	}

#r_sidebar ul {
	list-style: none;
	margin: 0px;
	padding: 0px 0px 20px 0px;
	}
	
#r_sidebar li {
	list-style: none;
	margin: 0px;
	padding: 0px;
	}
	
#r_sidebar ul li {
	list-style: none;
	margin: 0px;
	padding: 6px 0px 5px 0px;
	}
#r_sidebar ul li a {
	color: #c04080;
	text-decoration: none;
	}

#r_sidebar ul li a:hover {
	color: #c04080;
	text-decoration: underline;
	}

Hello All. I'm working on an assignment for an introductory level html/css class. The assignment asks me to change the Window Background color to 666666. How do i do this? So far i've only be able to change background colors of element tags, which is not what i need. This was the Example give for this particular step.

Edit: i tried to link a picture for a visual. For some reason its blocked to new members.

Any help would be appreciated.

What is wrong with this? I can't seem to see any of the background colors in Firefox or Camino? I have tried setting the background color in the body, and by enlosing the rest of the elements within a containing "main" div... but neither seem to work. Any ideas?

Right now the property is just "background" but I have tried...

background-color:

I am using a Wordpress template called Arthemia Premium. I want to change the background color in the headline section, but nothing "sticks" when I change the hex color codes in the style.css.

Tell me what to post here and I will.

Thanks

BTW I have very basic knowledge of CSS

Here is my code:

Code:

body { 
background-color: yellow; 
margin-left: 20%; 
margin-right: 20%; 
border: 1px dotted gray; 
padding: 10px 10px 10px 10px; font-family: sans-serif; 
}

None of the attributes such as background color, margins, border, padding are showing up when I test it out. Can someone help me?
