I'm following the book http://pragprog.com/book/rails4/agile-web-development-with-rails and my scss files aren't working.
The css file is this one:
.store {
h1 {
margin: 0;
padding-bottom: 0.5em;
font: 150% sans-serif;
color: #226;
border-bottom: 3px dotted #77d;
}
/* An entry in the store catalog */
.entry {
overflow: auto;
margin-top: 1em;
border-bottom: 1px dotted #77d;
min-height: 100px;
img {
width: 80px;
margin-right: 5px;
margin-bottom: 5px;
position: absolute;
}
h3 {
font-size: 120%;
font-family: sans-serif;
margin-left: 100px;
margin-top: 0;
margin-bottom: 2px;
color: #227;
}
p, div.price_line {
margin-left: 100px;
margin-top: 0.5em;
margin-bottom: 0.8em;
}
.price {
color: #44a;
font-weight: bold;
margin-right: 3em;
}
}
}
and the html file the following:
<% if notice %>
<p id="notice"><%= notice %></p>
<% end %>
<h1>Your Pragmatic Catalog</h1>
<% #products.each do |product| %>
<div class="entry">
<%= image_tag(product.image_url) %>
<h3><%= product.title %></h3>
<p><%= sanitize(product.description) %></p>
<div class="price_line">
<span class="price"><%= product.price %></span>
</div>
</div>
<% end %>
The CSS is loading properly, but not being applied. However if add a surrounding div with the class "store" it works. The book doesn't refer this situation, and I believe it should "automatically" apply the style, right?
Thanks.
**EDIT********
I found the problem. For those who may encounter the same issue, check the file:
app/assets/views/layouts/application.html.erb
body tag should have the following code:
<body class="<%= controller.controller_name %>">
Great that you found out the solution. But im trying to explain what happened behind the scene.
The way you are using the css is not a general convention. This facility comes with some additional gem. Check this link https://stackoverflow.com/a/4564922/1160106. With these gems you are able to design your css more DRY way.
General Convention
if you want to apply style to the following h1 element
# Here "store" class is the parent element of "h1"
<div class="store">
<h1> some text </h1>
</div>
Will require following way of css
#Here also "store" is written before "h1"
.store h1
{
#some designs
}
Whats happening in your case?
Probably you are maintaining controller wise css files. And presuming that you have a stores_controller. Thats why the classes for your stores_controller is encapsulated in .store {} block. Like
.store {
h3 {font-size: 120%;}
}
So it is clear that your h3 elements require a parent element having store class. And you are doing so by adding class="<%= controller.controller_name %>" with your body tag. Undoubtedly the <body> tag is parent of all following nodes. Now when you are hitting stores_controller it sets class="store" and your styles are working.
The approach is really DRY and recommendable.
As per your code all the styling is between the .store { } block, so it will not reflect as long as you surrounding div with the class "store"
For example
.store {
h3 {
font-size: 120%;
font-family: sans-serif;
margin-left: 100px;
}
}
is same as
.store h3 {
font-size: 120%;
font-family: sans-serif;
margin-left: 100px;
margin-top: 0;
margin-bottom: 2px;
color: #227;
}

<p>A CSS dropdown menu example using tetrapod groups as navigation items. The "Mammals" item provides an example of a multi-level dropdown. See the HTML Dog Dropdowns tecnhique article for more information.</p>
<p>Tetrapods are a major group of animals containing those that evolved from fish and developed four limbs. They comprise the major sub-groups of amphibians, reptiles, mammals, and birds. "Tetrapod" literally means four-footed.</p>

This looks like an I.E. standards mode issue. Add a line in your HEAD section to force I.E. 11 mode:
<meta http-equiv="x-ua-compatible" content="IE=11">
You can experiment with lower version numbers until it breaks again.
Oops, just spotted your Edit, too late.
Typically, to insert a Glyphicon inside a Bootstrap 3 app, it's as simple as:
<span class="glyphicon glyphicon-envelope"></span>
etc. In many apps, however, it is typical for Glyphicons to be "customized" so that they appear with numeric superscripts like so:
Above, this red/white "5" bubble might indicate that the user has 5 notifications. I'm wondering how this "numeric superscript" effect can be achieved in Bootstrap 3.
You mean something like this?
This is just some CSS basic styling, there is afaik no "standard" and certainly no special HTML tags nor "secret" bootstrap features that supports it. Below my suggestion - modify so it fit your expectations :
.rw-number-notification {
position: absolute;
top: -7px;
right: -6px;
padding: 3px 3px 2px 3px;
background-color: red;
color: white;
font-family: arial;
font-weight: bold;
font-size: 10px;
border-radius: 4px;
box-shadow: 1px 1px 1px silver;
}
markup :
<span class="glyphicon glyphicon-envelope">
<span class="rw-number-notification">7</span>
</span>
demo with some examples -> http://jsfiddle.net/rqfthhkx/
NB: Not completely related, but I do believe, though, that it is common practice to use the <i> tag when you are using glyphicons, fontawesome etc
<i class="glyphicon glyphicon-envelope"></i>
at least it renders as exactly the same -> http://jsfiddle.net/rqfthhkx/1/
Font Awesome
Example:
<i class="fa fa-envelope text-primary">
<span class="number-notification">7</span>
</i>
The .number-notification CSS is the same, except it seems impossible to adjust the position of the number container to fa-xx sizes and different font-sizes. The solution is to wrap the <i> element into <h> elements and specify the relative position in rem units :
.number-notification {
position: relative;
padding: 3px 3px 2px 3px;
background-color:red;
color:white;
font-family: arial;
font-weight:bold;
font-size: 10px;
border-radius: 4px;
box-shadow:1px 1px 1px silver;
}
.fa .number-notification {
top: -1rem;
right: 1rem;
}
h3 .fa .number-notification {
top: -1.2rem;
right: 1.2rem;
}
h2 .fa .number-notification {
top: -1.5rem;
right: 1.5rem;
}
h1 .fa .number-notification {
top: -2.2rem;
right: 1.8rem;
}
This should look more or less the same with different font sizes.
New fiddle -> http://jsfiddle.net/b86oj9gd/
I am trying to align a set of "buttons" made out of DIV elements that are arranged along the bottom of a web page using the CSS display: inline-block. I've attached a fiddle which illustrates the issue.
The problem is that this current code works on all modern browsers except Safari (7, 8). I don't know if this is a bug in WebKit that Safari uses, or something that I've allowed to happen by not using the right incantations.
The thing that triggers the unwanted behavior is the nested DIV.btn-sub; however, removing that text is not an option to "fix" the issue.
Here's the expected behavior (snap taken from Firefox 34, similar behavior on IE 9, 10, and latest Chrome):
Here's what happens on Safari:
Any help here would be appreciated!
It's usually best practice to use a list when creating inline-blocked elements in a row/list, such as a navigation.
The issue here seems to be the block being set with a padding directly; relative it's parent. Which somehow is turning it into a margin or something similar.
You can try stripping CSS until you get a full height out of the blocks, and then add another inner div which you can call .btn-padding which contains your top padding.
Here is similar.
body, html {
height: 100%;
margin: 0;
background: green;
}
#wrap {
display: block;
width: 100%;
position: fixed;
bottom: 0px;
height: 50px;
border:0;
background-color: blue;
color: #fff;
}
#btnls {
display: block;
list-style-type: none;
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}
#btnls li {
display: inline-block;
margin-right: 10px;
background-color: purple;
min-width: 158px;
max-width: 300px;
height: 50px;
text-align: center;
vertical-align: middle;
cursor: pointer;
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
}
#btnls li .btn-padding {
display: block;
padding-top: 10px;
width: 100%;
height: 50px;
}
#btnls li .btn-padding .sub-btn {
display: block;
font-size: x-small;
margin: 0;
padding: 0
}
<div id="wrap">
<ul id="btnls">
<li>
<div class="btn-padding">Foo
<div class="sub-btn">Bar</div>
</div>
</li>
<li>
<div class="btn-padding">Foo</div>
</li>
<li>
<div class="btn-padding">Foo</div>
</li>
</ul>
</div>
I am having trouble centering my navigation bar, I have tried display:inline-block and then align center like most posts suggest but it doesn't seem to be working.
HTML:
<!--Navigation-->
<div class="band navigation">
<nav class="container primary">
<div class="sixteen columns">
<ul>
<li>Home</li>
<li>About Us</li>
<li>Projects</li>
<li>Contact Us</li>
</ul>
</div>
</nav>
</div>
CSS:
nav.primary{
display: table;
margin: 0 auto;
}
nav.primary ul, nav.primary ul li {
margin: 0px;
}
nav.primary select {
display: none;
width: 100%;
height: 28px;
margin: 21px 0;
}
nav.primary ul li {
display: inline;
float: left;
position: relative;
}
nav.primary ul li a {
display: inline-block;
line-height: 49px;
padding: 0 14px;
color: white;
text-transform: uppercase;
text-decoration: none;
font-weight: bold;
letter-spacing: 0.08em;
background: ##999999;
}
nav.primary ul li a:hover {
background: #2ecc71;
cursor: pointer;
}
Ok finally got it:
nav.primary ul li {
display: inline;
float: left; <---
position: relative;
Remove the float: left;
Since the navigation is the full width of the containing div, there is no need to mess with floats, the list items will line up with just display: inline;
I tried something else that works... It seems to work better than trying to build in something custom thus far in my experience with Skeleton... Although it produces a bit less pretty markup for the HTML, the rigidity of the final result works for me. Here is my code so that you can see what I did to achieve the desired effect:
<div class="row">
<div class="two columns offset-by-three">
Portfolio
</div>
<div class="two columns">
About
</div>
<div class="two columns">
Contact
</div>
</div>
What you can see here is that the skeleton framework allows for the columns to operate naturally and restack at lower resolutions without any extra code. The only tricky part really is setting up the offset on the left most item.
Have you tried nav.primary ul {text-align: center;}
As well as keeping the left/right margins to auto, this worked for me when I was using the skeleton framework.
What would be the best way to write this old CSS using LESS?
.paginationContainerTop {width:100%; margin-bottom:10px;}
.paginationContainerTop .paginationNav {float:right; text-align:right;}
.paginationContainerBottom {width:100%; margin-top:10px;}
.paginationContainerBottom .paginationNav {float:right; text-align:right;}
Based on my understanding, it would be something like:
.paginationNav {
float: right;
text-align: right;
}
.paginationContainerTop {
margin-bottom: 10px;
.paginationNav;
}
.paginationContainerBottom {
margin-top: 10px;
.paginationNav;
}
You don't need to nest .paginationNav; as a mixin inside your other divs.
Tom is right, it seems Top/Bottom should be IDs, and might not even be necessary? I'm imagining your HTML to look something like this:
<div id="header">
<div id="paginationNavTop">
<div id="paginationNav">[nav stuff]</div
</div>
</div>
[body stuff]
<div id="footer">
<div id="paginationNavBottom">
<div id="paginationNav">[nav stuff styled differently]</div
</div>
</div>
If that's the case, you could write this as your CSS:
.paginationNav {float: right; text-align: right;}
#header .paginationNav {margin-bottom: 10px;}
#footer .paginationNav {margin-top: 10px;}
instead of having Top and Bottom specific styles.
In LESS, you could nest the code like this:
.paginationNav {float: right; text-align: right;}
#header {
.paginationNav {margin-bottom: 10px;}
}
#footer {
.paginationNav {margin-top: 10px;}
}
The simple answer is
.paginationContainerTop, .paginationContainerBottom {width:100%;}
.paginationNav {float:right; text-align:right;}
.paginationContainerTop {margin-bottom:10px;}
.paginationContainerBottom {margin-top:10px;}
but that's doing you a disservice. It looks like you're using classes for what should be IDs. If I'm reading your code correctly, you probably want to break the shared properties out into classes and then use IDs (#paginationContainerTop instead of .paginationContainerTop) for the properties that are specific to individual elements. However, in this case you're specifying a property (width: 100%) that is the default unless it inherits something you've changed, so the CSS can be further trimmed to:
.paginationNav {float:right; text-align:right;}
.paginationContainerTop {margin-bottom:10px;}
.paginationContainerBottom {margin-top:10px;}
Also note that I've taken away the .paginationContainerTop/Bottom qualification from your .paginationNav styles: unless you need to override something or this will create a conflict, there's no need to specify an inheritance chain.
.paginationContainerTop {
width: 100%;
margin-bottom: 10px;
.paginationNav {
float: right;
text-align: right;
}
}
.paginationContainerBottom {
width: 100%;
margin-top: 10px;
.paginationNav {
float: right;
text-align: right;
}
}
i just used this tool to convert your css to less:

hope this helps :)
