In order to easily distinguish between production and staging web site, I would like to apply different CSS styles, based on the Rails environment.
What is the best way to accomplish this please?
You can use Rails.env.production? and add some class to div, body etc...
If you want to do it global in you application layout add something like:
<!-- application_layout -->
<body class="<%= Rails.env.production? ? 'prod-class' : 'dev-class' %>">
</body>
If is only for some div or element:
<div class="<%= Rails.env.production? ? 'prod-class' : 'dev-class' %>">
</div>

I'm trying to create a fixed Navbar using Project Clarity
I'm using it in my Angular project, they are using FlexBox, I have tried putting in position: fixed but it doesn't seem to work, anyone have any ideas ?
<clr-header class="header-6">
In order to fix the header so that content scrolls underneath it, your application needs to have the correct Application Layout. Our components work within this structure because A properly structured layout enforces an optimal, consistent experience across applications.
The general structure for A Clarity Application layout takes this form:
<div class="main-container">
<div class="alert alert-app-level">
...
</div>
<header class="header header-6">
...
</header>
<nav class="subnav">
...
</nav>
<div class="content-container">
<div class="content-area">
...
</div>
<nav class="sidenav">
...
</nav>
</div>
</div>
Obviously, you can get rid of the parts that may not be relevant to your app like: alert-app-level, subnav etc ...
You can see this working in a quick demo I made with inspiration from Bob Ross. As you can see the content scroll underneath the application header.
if someone has also either very this problem, or another problem where some css does not work within Angular:
Since we mostly structure our UI code in multiple components in Angular, and since each component puts its own host-tag in the generated DOM between the actual html tags, the clarity library has some problems with it.
So as a workaround, if you still want to be able to keep your current htmls as they are, you can define this css in each your component's css file:
:host { display: contents; }
This causes the component's box not to render; means the host tags are still visible in DOM, but they will not have any effect regarding CSS. And any clarity CSS will work again.
I'm about to start a new project using Aurelia and I'm considering to use it in conjunction with CSS BEM methodology.
First question: Is this basically considered a good match or are there any alternatives which "fit" better with Aurelia?
Main question:
Best explained with an example for some custom Aurelia view (an app header):
<template>
<div class="AppHeader">
<span class="AppHeader-logo"></span>
<span class="AppHeader-text"></span>
<app-menu></app-menu>
</div>
</template>
When embedded into another view, this leads to a resulting DOM like this (simplified):
<app-header>
<div class="AppHeader">
<span class="AppHeader-logo"></span>
<span class="AppHeader-text"></span>
<app-menu>
<!-- ... -->
</app-menu>
</div>
</app-header>
Obviously, the wrapper div with the AppHeader class is kind of superfluous since there's also the app-header tag. Unfortunately it doesn't seem to be possible to assign the CSS class AppHeader (which is needed for BEM) to the base element of the view (the template tag in the view file).
Are there any alternative ways that I'm not aware of or is it considered "good" practice (or at least acceptable) to have many wrapper elements inside views which somehow bloat the DOM?
I just realized, that putting custom classes on the custom elements themselves (the template) actually works, so I can simply write something like this:
<template class="AppHeader">
<span class="AppHeader-logo"></span>
<span class="AppHeader-text"></span>
<app-menu></app-menu>
</template>
Edit / Additional info
This won't work if the view is a "base view" of a route since the template element won't be rendered at all in this scenario but is replaced by the router-view element.
I believe that even a hundred extra DOM nodes is not a problem for contemporary browsers but if it's really important to avoid them you may try custom tags instead of classes (see list of restrictions here https://en.bem.info/methodology/faq/#why-are-custom-tags-not-used-for-blocks-in-bem).
Perhaps the #containerless will solve your problems:
In your view model:
#containerless
export class AppHeader {
...
}
In this way, the <app-header> container will not be rendered.
If your component is a view-only component, you can declare containerless in the <template> tag:
<template containerless>
<div class="AppHeader">
<span class="AppHeader-logo"></span>
<span class="AppHeader-text"></span>
<app-menu></app-menu>
</div>
</template>
This question may sound a bit weird/novice/stupid. Please bear with me.
The below code is a small portion of a webpage I have created using CSS,
HTML and coldfusion.
<head>
---------------------Part 1--------------------------------------
<CFIF CompareNoCase('#aid#', 0)>
<cfinclude template="show.cfm">
<cfabort>
</CFIF>
-----------------------------------------------------------------
<link rel="stylesheet" href="styles/style.css?1322665623">
</head>
---------------------------PART 2------------------------------------
<body id="wp-home">
<div id="wrapper">
<div class="header left">
<h1>Name Of Client</h1>
<div class="tagline">
<span class="left blair">home</span>
<span class="headerline"></span>
<span class="right blair">antiques</span>
</div>
</div>
--------------------------------------------------------------------
As you see, I have included a css file, style.css which contains all the style classes required to display PART 2 correctly.
Problem is, whenever part 1 is active ( is true), the same
css is applied to elements in file SHOW.CFM also. This totally messes up the page's original display.
For the time being I have placed a tag below the link to stop page from processing and the css file being loaded.
I have checked show.css multiple times and can confirm that no class from styles.css is used in it.
Hence, my question is if I can stop the styles from style.css to be applied on elements loaded from SHOW.CFM
Pardon me if the question is insanely stupid ;)
If a selector matches then a rule will apply until overridden by a rule (which sets the same property) further down the cascade.
You can either change your selectors to stop them matching the elements you don't want them to match, or you can override all your rules in that section.
HTML5 allows scoped stylesheets, but only Firefox supports it so far. There is also a polyfill JavaScript.
Therefore, you'll have to adapt your markup and styles so that it only matches part2, and not part1. In a pinch, you can precede every selector with #wrapper. For example, if a rule says a{color:red}, substitute that with #wrapper a {color:red;}.
By the way, part1 should probably be a child of <body> instead of <head>.
Use the pseudo-class :not():
.myStyle:not(.classWhereYouDontWantToApplyTheStyle) {
...
}
What about using if else instead of just if to determine which css file you should include? In other words, include styles.css only when part 2 displays. That way, you avoid inheritance and scoping issues altogether.
I'm building a table cell using two bound ember.js views on data. When I do that, ember.js inserts its metamorph tags such that it can update the view later.
<td>
<a data-ember-action="14">
<div id="ember2065" class="ember-view">
<script id="metamorph-102-start" type="text/x-placeholder"></script>
02/04/2012
<script id="metamorph-102-end" type="text/x-placeholder"></script>
</div>
#
<div id="ember2072" class="ember-view">
<script id="metamorph-103-start" type="text/x-placeholder"></script>
$61.81
<script id="metamorph-103-end" type="text/x-placeholder"></script>
</div>
</a>
</td>
These tags cause the date and the price below to line wrap within the cell. Is there a CSS styling that I can apply to these tags to make them not effect line breaking?
It strongly depend on your full case. It seems to me that using views is superfluous here, but maybe I am missing some information.
Here are some working samples: http://jsfiddle.net/MikeAski/QCbGN/
Maybe providing more context would help to have better sample.
Put this in your stylesheet to prevent line breaks from ember views:
div .ember-view {
display: inline;
}
i have a submit button with the code inside a form
<li>
<input id="zip" name="zipcode" type="submit"
class="zip-button" value="Find" tabindex="{counter name=tabindex}"/>
</li>
.zip-button{
height:30px;
------}
.zip-button:focus,.zip-button:hover{------}
for some reason the zip is not getting any style.but if manually add it in jquery like
$("#zip").css({"height":"30px",...});
its working.As am very new to styling i couldn't figure it.
Sometimes the cascade in CSS is a possible reason for the that case. Another rule with higher precedence is able to overwrite the definition. Firebug is a great tool for "debugging" css code.
It shows, how the browser interprets the style sheets.
Is your css directly in the page like that? if so, that is the reason. You need to use inline styles, a style tag or an external css file.
inline:
<input style='height:30px;' ...
style tag:
<html>
<head>
<style type='text/css'>
.zip-button{ height:30px; }
</style>
...
external file
sometimes we might be referring to minified css(abc.css.min) file in which some classes might be missing (my case)instead of the original source css.this might result in styles missing for few class which are absent in css.min ....we can find out this using FireBug...in this case we need to go back and set reference right...[am a beginner so bare with my technical terms usage]
