Background-color Css - css

I am using bootstrap 3.0 and the following is my HTML code , I am facing a problem with the background color.
HTML code
<div class="container" id="pictures">
<div class="row">
<div class="col-md-12">
<h1>Collection</h1>
</div>
</div>
</div>
CSS code (I have targeted the H1 tag using this css code)
#pictures h1 {
padding:10px 0;
color: #fff;
font-size:60px;
background-color: #f92735;
text-align: center;
margin: 60px 370px;
border-radius: 10px;
margin-top: -65px;
}
Heres the problem , as i size down my browser horizontally , the background color disappears . can somebody tell me why ?

The problem come from the following styles you have applied for h1
margin: 60px 370px;
It means it required minimum (370+370) width to show your h1 tag. Reduce the margin to less number then you can see it in small screens also.
#pictures h1 {
padding:10px 0;
color: #fff;
font-size:60px;
background-color: #f92735;
text-align: center;
margin: 60px 30px;
border-radius: 10px;
margin-top: -65px;
}

Div tag border with title

I need to display a border around a div tag with a title in the border itself. In order to do this, this is what I have come up with so far
.componentWrapper {
border: solid cadetblue;
border-radius: 40px;
padding: 10px;
width: 95%;
}
.componentTitle {
font-size: 18px;
width: 15%;
background-color: white;
margin-top: -25px;
}
<div class='componentWraper'><p class='componentTitle'>This is the title</p>This is the component body text</div>
As you can see I am using margin property to push the title up on top of the border. I am not sure if this is the proper approach to do this and I have the following questions.
I am positioning the title using pixels (margin) and a fixed value (-25px). This is a site that has to work on mobile phones, tablets as well. Is this an acceptable approach?
I am setting the background-color to white so that the border does not appear behind the text, is this an ok approach?
Is there a better and more acceptable way to do this, I do not want to use fieldset because we have little control over the border (border-radius).
There are three logical ways you can use to achieve this.
You can use a <fieldset> with a legend which is the basic HTML way of doing this. You can find more information about this here.
Use custom CSS with positioning, not negative margins or etc.:
body {
background: #fff;
}
.componentWraper {
margin: 40px; /* just for contrast */
position: relative;
border: 2px solid tomato;
border-radius: 12px;
padding: 20px;
}
.componentWraper .componentTitle {
position: absolute;
top: -25px;
background: #fff;
padding: 0 10px;
}
<div class='componentWraper'>
<p class='componentTitle'>This is the title</p>This is the component body text</div>
Use custom CSS with pseudo-elements:
body {
background: #fff;
}
.componentWraper {
margin: 40px; /* just for contrast */
position: relative;
border: 2px solid tomato;
border-radius: 12px;
padding: 20px;
}
.componentWraper::before {
content: 'This is the title';
position: absolute;
top: -10px;
padding: 0 10px;
background: #fff;
}
<div class='componentWraper'>This is the component body text</div>
I think you're on the right track. I'd make a few changes to have more control over the styling. You can use ems or pixels.
Wrap the title and content in a new div and give that a negative margin:
<div class='componentWrapper'>
<div>
<div class='componentTitle'>This is the title</div>
<div class='componentContent'>
<p>This is the component body text</p>
</div>
</div>
.componentWrapper div {
margin-top: -1em;
}
Set your title to display: inline-block and use padding to control the white space around it (instead of using width)
.componentTitle {
font-size: 18px;
background-color: white;
display: inline-block;
padding: .5em;
}
codepen
snippet:
.componentWrapper {
border: solid cadetblue;
border-radius: 40px;
padding: 10px;
width: 95%;
margin-top: 1em;
}
.componentWrapper div {
margin-top: -1.2em;
}
.componentTitle {
font-size: 18px;
background-color: white;
display: inline-block;
padding: .5em .3em;
}
<div class='componentWrapper'>
<div>
<div class='componentTitle'>This is the title</div>
<div class='componentContent'>
<p>This is the component body text</p>
</div>
</div>
This is what I came up with. I wanted to get rid of the negative margin, but couldn't figure out a way to do that.
See the Pen offset title by Yvonne Aburrow (#vogelbeere) on CodePen.
HTML
<div class="componentWrapper">This is the component body text</div>
CSS
.componentWrapper {
border: 1px solid blue;
border-radius: 40px;
padding: 16px;
width: 95%;
margin: 3em;
}
.componentWrapper:before {
content: "this is the title";
font-size: 18px;
width: 10%;
background-color: white;
border: 1px solid blue;
border-radius: 12px;
display: block;
margin-top: -29px;
padding: 3px;
}
I am not sure how a screen reader would deal with the title text being in the CSS (or how you would scale that up if you have a lot of different titles.

Px to Em conversion incorrect when positioning paragraph?

I'm experiencing an odd issue when trying to position a (inline-block) paragraph using em values vs. px.
Body font size = 16px = 1em
I positioned the paragraph ("Organization Name") to have a top margin of 20px and left margin of 10px:
body {
font-size: 16px;
width: 60em;
border: 1px solid black;
}
#topHeader {
min-height: 4.69em;
margin-top: .31em;
border-bottom: 1px solid black;
}
#topHeader img {
float: left;
height: 70px;
width: 100px;
margin-left: .63em;
}
#headerTitle {
display: inline-block;
font-size: 2em;
margin: 20px 0px 0px 10px;
}
#topUserLinks {
display: inline;
float: right;
}
#topUserLinks a {
display: inline-block;
margin-right: 10px;
}
#topNav {
padding-left: 400px;
margin-top: 5px;
}
#topNav a + a{
margin-left: 30px;
}
<header id="topHeader">
<img src="" alt="Organization Image Here">
<p id="headerTitle">Organization Name</p>
<div id="topUserLinks">
Sign Up
Login
</div>
<nav id="topNav">
Link 1
Link 2
Link 3
Link 4
Link 5
</nav>
</header>
I then converted the paragraph positioning to the em equivalent of 1.25em top and .63em left:
body {
font-size: 16px;
width: 60em;
border: 1px solid black;
}
#topHeader {
min-height: 4.69em;
margin-top: .31em;
border-bottom: 1px solid black;
}
#topHeader img {
float: left;
height: 70px;
width: 100px;
margin-left: .63em;
}
#headerTitle {
display: inline-block;
font-size: 2em;
margin: 1.25em 0em 0em .63em;
}
#topUserLinks {
display: inline;
float: right;
}
#topUserLinks a {
display: inline-block;
margin-right: 10px;
}
#topNav {
padding-left: 400px;
margin-top: 5px;
}
#topNav a + a{
margin-left: 30px;
}
<header id="topHeader">
<img src="" alt="Organization Image Here">
<p id="headerTitle">Organization Name</p>
<div id="topUserLinks">
Sign Up
Login
</div>
<nav id="topNav">
Link 1
Link 2
Link 3
Link 4
Link 5
</nav>
</header>
Obviously I expected the positioning of the paragraph to remain the same. As you can see in the above snippet, it's margins seemed to double!
I can easily correct this by just reducing the em values, but I really want to understand why this happened in the first place.
My conversions from px to em are correct ((20/16=1.25)(10/16=.63)), so I am struggling to understand this issue. Any advice or insights you could offer would be appreciated!
You #headerTitle paragraph is set to a font size of 2em, so that's the measure of your em margins. (I.e. 1em is now around 32px for that element.) Forget about matching px with em in this way, though. If you want your em margins based on the root document's em setting, set the font size of the html element to 16px or 1em and then use rem instead of em for the margins.
(As an aside, the organisation name there isn't really a paragraph. I'd either use a heading element or just a div as a container.)

Fix the alignment of two child divs

The project is to create a micro-blogging website similar to Twitter. I chose to name the site Chirper (how clever of me). Each post is structured by a parent div, an avatar div and a content div. The avatar and content divs are displayed inline, but they are not aligned properly. Any help is appreciated.
HTML:
<div class="chirp">
<div class="chirp_avatar_region">
<img src="img/avatar/default.png" alt="Avatar" width="64" height="64">
</div>
<div class="chirp_content">
<p>

</div>
The div's aren't aligned how I want them to be (level and 100% of the parent).
I can't post images, so here is a link to an imgur page: http://imgur.com/Mn9mE5q
Relevant CSS:
body {
font-family: Verdana, Geneva, sans-serif;
color: #000;
background-color: #666;
font-size: 1em;
}
/* Containers */
div {
margin-top: auto;
margin-left: auto;
margin-right: auto;
margin-bottom: 10px;
border-style: solid;
border-width: 3px;
border-color: #000;
padding: 10px;
}
div.pane {
width: 70%;
background-color: 0099FF;
}
div.chirp {
border-width: 1px;
margin-bottom: -1px;
width: 80%;
padding: 5px;
}
div.chirp_avatar_region {
display: inline-block;
width: 10%;
height: 100%;
text-align: center;
/*border-style: none;*/
}
div.chirp_content {
display: inline-block;
width: 80%;
height: 100%;
/*border-style: none;*/
}
div.chirp_avatar_region > img, div.chirp_content > p {
margin-top: 0;
vertical-align: middle;
}
You can either float your inner divs then clear the float following the container
or
use vertical-align:top to position your divs at the top of the container
Not entirely sure, but what I think is happening is that by defining position:inline-block, it's putting them on the same line, and making the line-height the height of the chirp_content container. In a sense anyway.
Set to vertical-align:top; and it should solve it.
Ex.
.chirp_content, .chirp_avatar_region{ vertical-align:top; }
JS Fiddle
Give to the avatar_region a float: left, and remove its width: and height: setting. Remove the chirp_content div, it circumvents the inlining.

Vertically align inline object without height or width

Given the following html:
<div class="body">
<div class="banner">
<div class="name">

<a href="http://www.example.com">
<span class="bold">Test Link</span><br/>
</a>
</h2>
</div>
<div class="title">

How can I vertically align .link a (the button) within .link without giving a height or width? Like this...
Here's my fiddle
Here is one way that you can do it. Your HTML is good, no need to change anything.
For the CSS:
.body { width: 920px; }
.banner {
background-color: #454545;
border-bottom: 3px solid #F9F9F9;
height: 100px;
margin: 0 0 5px;
padding: 0;
display: table;
}
.banner > div {
outline: 1px dotted yellow; /* optional to show cell edges... */
display: table-cell;
}
.banner .name {
width: 25%;
vertical-align: top;
padding-top: 25px; /* control top white space */
text-align: center;
}
.banner .name h2 {
color: #F9F9F9;
max-height: 55px;
text-transform: uppercase;
margin: 0;
padding: 0;
}
.banner .title {
width: 50%;
vertical-align: top;
padding-top: 25px;
}
.banner .title h3 {
font-size: 15px;
font-weight: bold;
line-height: 15px;
margin: 0px 0 0 0;
padding: 0;
}
.banner .title p {
font-size: 12px;
max-height: 35px;
overflow: hidden;
margin: 0;
padding: 0;
}
.banner .link {
width: 25%;
vertical-align: middle;
text-align: left; /* set to left, center or right as needed */
}
.banner .link a {
margin-left: 25px; /* controls left offset */
background-color: #FA9800;
border-radius: 5px 5px 5px 5px;
cursor: pointer;
display: inline-block; /* use inline-block if you want to center element */
font-size: 12px;
font-weight: bold;
height: 23px;
line-height: 23px;
text-align: center;
text-decoration: none;
width: 100px;
}
See the fiddle at: http://jsfiddle.net/audetwebdesign/jsG8F/
How This Works
The trick is to use display: table on your .banner container and then display: table-cell on your child div elements, and set the % widths to 25%, 50%, 25% respectively for .name, .title, .link.
You can then use vertical-align and text-align to control vertical and horizontal placement of the various text blocks.
I added comments related to using padding-top to control white space from the top of the banner.
For the .link a element, you can adjust the left margin (or right) as needed.
These CSS rules offer you a lot of fine control over the placement of the various elements within the banner.
Backwards Compatibility
The display: table-cell property is backwards compatible back to IE8.
Reference: https://developer.mozilla.org/en-US/docs/Web/CSS/display
If the size of the element and banner are fixed, use margin-top to offset the element.
Marc Audet was very close but I ended up going a slightly different route.
I gave .link a a fixed top margin and made margin-left: auto; and margin-right: auto; and that did the trick.
Here is the fiddle for reference.

Background-color without height

I am building a fixed width site, 970px, centered, with a gradient as the surround. Originally the fixed width portion was white with several horizontal areas (menu, search area, product selection area) having a different background. This was accomplished simply with a background color of white for a div that is the next child of the body, which contained all the content of the page, and an override to the background color when needed. This worked fine.
Can I make these horizontal areas have the same background as the gradient, which will obviously be different at different places in the page? I thought I would simply keep the background-color transparent (the default) at all levels until I came to the parent of content I want white, making that parent's background-color #FFFFFF. This works if I specify a height to the area. However, the main body of the website will be of indeterminate height, and must be white (or something other than the gradient!). Are there any techniques through which I can force an element and its contents into a white background without specifying a height on that element?
Thanks.
Thanks for the response. I should clarify with code so that the question is clear. Sorry for that.
Here is sample HTML that illustrates the problem:
<body>
<div id="Page">
<div id="Header">
<div id="HeaderNavigationSection">
<div id="HeaderNavigationMenu">
<ul>
<li>Menu Item One</li>
<li>Menu Item Two</li>
</ul>
</div>
</div>
<div id="HeaderBannerSection">
<a href="#">
<img id="CompanyLogo" alt="Company Logo" src="" height="45" width="200" />
</a>
<p id="BannerSloganOne">Banner Slogan One Text</p>
<p id="BannerSloganTwo">Banner Slogan Two Text</p>
</div>
<div id="HeaderSearchSection">
<div class="HeaderSearchSectionLine">
<p class="HeaderSearchBoxLabel">Search Label One and Related Search Area</p>
</div>
<div class="HeaderSearchSectionLine">
<p class="HeaderSearchBoxLabel">Search Label Two and Related Search Area</p>
</div>
</div>
</div>
</div>
</body>
First, here is CSS that works, using a page-level white background color and a section level different background color (yellow for illustration). This works throughout my code. I do not show any resets or basic settings. Note that the commented-out CSS for the #HeaderBannerSection is not needed (it appears in the code that doesn't work, which is shown after this code).
html {
height: 100%;
background-color: #D4D4D4; /* surrogate for browser-specific gradient */}
body {
text-align: center;}
#Page {
width: 970px;
margin: 0px auto 10px auto;
line-height: 1.2;
font-family: Calibri, Arial, Helvetica, sans-serif;
font-size: 12px;
color: #000000;
text-align: left;
background-color: #FFFFFF;}
#HeaderNavigationSection {
height: 30px;
background-color: #FFFF00;}
#HeaderNavigationMenu {
display: inline;
float: right;}
#HeaderNavigationMenu li {
display: inline;
float: left;}
#HeaderNavigationMenu li a {
display: inline;
float: left;
margin: 8px 0px 10px 0px;
padding: 0px 10px 0px 10px;}
#HeaderBannerSection {
/*width: 970px;*/
/*background-color: #FFFFFF;*/}
#CompanyLogo {
display: inline;
float: left;
width: auto;
margin: 10px 0px 10px 10px;}
#BannerSloganOne {
display: inline;
float: left;
width: 330px;
margin: 20px 0px 20px 80px;}
#BannerSloganTwo {
display: inline;
float: right;
width: 300px;
margin: 20px 10px 20px 0px;
text-align: right;}
#HeaderSearchSection {
clear: both;
height: 68px;
background-color: #FFFF00;}
.HeaderSearchSectionLine {
clear: both;}
.HeaderSearchBoxLabel {
display: inline;
float: left;
margin: 10px 0px 0px 10px;}
Here are the changes to that CSS that attempt to make the html-level background color (namely the gradient) the default, through transparency, except where specifically overridden where desired (in this example, for the #HeaderBannerSection (with code from above commented out as needed)):
#Page {
width: 970px;
margin: 0px auto 10px auto;
line-height: 1.2;
font-family: Calibri, Arial, Helvetica, sans-serif;
font-size: 12px;
color: #000000;
text-align: left;
/*background-color: #FFFFFF;*/}
#HeaderNavigationSection {
height: 30px;
/*background-color: #FFFF00;*/}
. . .
#HeaderBannerSection {
width: 970px;
background-color: #FFFFFF;}
. . .
#HeaderSearchSection {
clear: both;
height: 68px;
/*background-color: #FFFF00;*/}
This code does not work. The background-color for the section that should be white instead remains the gradient. This is true unless I specify a height for the section, then it all works. But I won't be able to specify the height for the main section (not shown) unless I do a jQuery to determine rendered height and then do a jQuery css height setting (not ideal, and haven't even tried it yet to see if it works). Incidentally, the offending code does work in IE6 and IE7 (at least as rendered in Expression Web 4 SuperPreview).
Thanks again for any help you can give me.
For your banner section try this jsfidle
the min-width property forces the div to have a specific minimum width if the content inside it is not enough to fill it (it will be the specified width by default until the content in it is so much that the div has to expand)
I've changed the background colour so that you can see the actual div # work
feel free to change to #FFFFFF once you are sure you have gotten it correct.
