I'm using Kickstrap to theme my bootstrap app and my client wants users to be able to change themes on the fly. I know that to change the theme, all you have to do is change the directory in the themes.less file but I don't know the best way to go about this. Also, I want to remember a user's theme preference so I need to store a cookie to do this, but I'm not entirely sure if it's possible to read cookies straight into LESS as variables.
Basically, I just want a dropdown menu that allows users to select a theme from a list.
Any suggestions would be great! Thanks!
Assuming you're just using plain HTML/CSS/JavaScript and not a server-side framework, there are a few ways to do this. One involves actually modifying the LESS source code but let me offer some simpler ways:
I would try keeping theme.less blank, so it will just show a default Bootstrap theme.
then you can load your Kickstrap theme on a separate line like this:
<link rel="stylesheet/less" type="text/css" href="kickstrap.less" />
<link rel="stylesheet/less" type="text/css" href="mytheme.less" />
<script src="less.js"></script>
Two theme files
Of course, your theme might have two files, like variable.less and bootswatch.less which may not work keeping them separate:
<link rel="stylesheet/less" type="text/css" href="kickstrap.less" />
<link rel="stylesheet/less" type="text/css" href="variables.less" />
<link rel="stylesheet/less" type="text/css" href="bootswatch.less" />
<script src="less.js"></script>
So instead, you can just #import the variables.less file into bootswatch.less.
#import "variables.less";
And then use the original example from above.
<link rel="stylesheet/less" type="text/css" href="kickstrap.less" />
<link rel="stylesheet/less" type="text/css" href="bootswatch.less" />
<script src="less.js"></script>
By the way, if you're not using LESS client-side, no worries. Just use the compiled CSS files for each instead.
<link rel="stylesheet/less" type="text/css" href="css/kickstrap.css" />
<link rel="stylesheet/less" type="text/css" href="css/bootswatch.css" />
Writing to the DOM
As far as changing this in the DOM, I would try taking advantage of the cssIfy() function already in kickstrap.js. This will take a string (the .css filename) and write it as a stylesheet to the DOM. If you need to write it as a .less file, you can probably just manipulate this function easily. Maybe something like this:
function lessIfy(filePath) {
var linkElement = document.createElement("link");
linkElement.setAttribute("rel", "stylesheet/less");
linkElement.setAttribute("type", "text/css");
linkElement.setAttribute("href", filePath);
document.getElementsByTagName('body')[0].appendChild(linkElement);
}
If you do it this way, you'll need to make sure less.js loads afterwards, so try either appending it before that or (worse) loading less.js again after that.
Take a look at how the "Included Themes" option changes the themes as you select them.

I have this Plugin I want to use, it is a slider plugin, here's the link to it: https://github.com/seiyria/bootstrap-slider
I want use it using the CDN: https://cdnjs.com/libraries/bootstrap-slider
So in my header of the html I have it like this:
<head>
<title>Slider Test</title>
<link rel="stylesheet" type="text/css" href="bootstrap/css/bootstrap.min.css">
<script src="//cdnjs.cloudflare.com/ajax/libs/bootstrap-slider/9.2.0/bootstrap-slider.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/bootstrap-slider/9.2.0/bootstrap-slider.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/bootstrap-slider/9.2.0/css/bootstrap-slider.css"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/bootstrap-slider/9.2.0/css/bootstrap-slider.min.css"></script>
</head>
And then I try to use one of the examples they show on their page: http://seiyria.com/bootstrap-slider/
Example 21:
<input id="ex21" type="text"
data-provide="slider"
data-slider-ticks="[1, 2, 3]"
data-slider-ticks-labels='["short", "medium", "long"]'
data-slider-min="1"
data-slider-max="3"
data-slider-step="1"
data-slider-value="3"
data-slider-tooltip="hide" />
As a result all I get is a text box. Am I not using the plugin or referencing it the right way ?
First: you only need either the full or the minfied versions. In your example code you're including both.
For development purposes I propose to remove the includes of the minified files (the one with the .min suffix.
Secondly, you are including the stylesheets through script tags. You need to include a stylesheet using a link tag.
Lastly, I do not see an include of the Bootstrap JavaScript itself, you'll need to include it as well.
I would also update the path to the bootstrap-slider files. Using two slashes at the start could lead to strange behaviour. Update them to use https:// as the prefix.
After these changes your head section should look like
<head>
<title>Slider Test</title>
<link rel="stylesheet" type="text/css" href="bootstrap/css/bootstrap.min.css">
<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-slider/9.2.0/css/bootstrap-slider.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/js/bootstrap.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-slider/9.2.0/bootstrap-slider.js"></script>
</head>
I have a Vb.net MVC application that utilises Kendo UI (in the Bootstrap theme). I was told I had too many/conflicting css and js files declared but I'm struggling to figure out what my minimum requirements are. I'm also aware I may have some in the wrong order. I tried to fix this but have now managed to cause all dropdowns to display object [object] instead of the selected value.
I have the following declared...
<link href="#Url.Content("~/Content/kendo/2016.1.112/kendo.common-bootstrap.min.css")" rel="stylesheet" type="text/css" />
<link href="#Url.Content("~/Content/kendo/2016.1.112/kendo.bootstrap.min.css")" rel="stylesheet" type="text/css" />
<link href="#Url.Content("~/Content/kendo/2016.1.112/kendo.mobile.common.min.css")" rel="stylesheet" />
<link href="#Url.Content("~/Content/kendo/2016.1.112/kendo.bootstrap.mobile.min.css")" rel="stylesheet" type="text/css" />
<link href="#Url.Content("~/Content/kendo/2016.1.112/kendo.dataviz.bootstrap.min.css")" rel="stylesheet" />
<script src="#Url.Content("~/Scripts/jquery-2.1.4.min.js")"></script>
<script src="#Url.Content("~/Scripts/kendo/2016.1.112/jszip.min.js")"></script>
<script src="#Url.Content("~/Scripts/kendo/2016.1.112/kendo.all.min.js")"></script>
<script src="#Url.Content("~/Scripts/kendo/2016.1.112/kendo.mobile.min.js")"></script>
<script src="#Url.Content("~/Scripts/kendo/2016.1.112/kendo.aspnetmvc.min.js")"></script>
Any help appreciated as I have no backup of the file before I started 'messing' and now do not know what was there originally and in which order. :(
All the help you need is here : http://www.telerik.com/blogs/which-css-files-to-use-in-your-kendo-ui-project
After reading the article, I am still not sure that if you use kendo.mobile, you still need kendo.common for the css and kendo.all.min for the js if your application is also desktop.
I cant seem to find a way to exclude my layout in express. I tried doing
response.render("index",{layout: false});
but that disables the css for the page. Is there something im missing here? What is the best way to disable the layout but keep the css?
Also, I'm using app.use(express.static("public")); and my css is in the public folder.
This is happening because your layout is including the CSS. Try instead making a layout that just has the code to include your css and nothing else. Like so:
/* Using handlebars templateing for this example */
<link rel="stylesheet" type="text/css" href="styles.css" />
{{{ body }}}
This will just include the css and then display your content.
<link rel="stylesheet" type="text/css" href="styles.css" /> is the code to include your css
{{{ body }}} is the code to include your content.
However it is not possible to include css without a layout unless it is in your content.
So if you want to use {layout: false} the css inclusion code(<link rel="stylesheet" type="text/css" href="styles.css" />) has to be in your content
I have a master page with the following lines inside my <head> tags.
<link href="Styles/Style.css" rel="stylesheet" type="text/css" />
<script src="Scripts/navmenu.js" type="text/javascript"></script>
When I navigate to a page that uses URL routing, the lines above generate the following HTML.
<link href="../../Styles/Style.css" rel="stylesheet" type="text/css" />
<script src="Scripts/navmenu.js" type="text/javascript"></script>
Based on the mapped URL, the stylesheet link is correct. How can I get the script link to also be correct?
P.S. I tried setting runat="server" in the script link but that just seems to confuse ASP.NET. The entire project fails to compile based on bogus errors reported in my JavaScript file. (The javascript file runs fine otherwise.)
It looks like the best answer is this:
<link href="Styles/Style.css" rel="stylesheet" type="text/css" />
<script src='<%= ResolveClientUrl("~/Scripts/navmenu.js") %>' type="text/javascript"></script>
Note that if I use the ResolveClientUrl() for the stylesheet <link> tag, it doesn't work. Apparently, there is special handing for this tag.
I have a page where there is a lot of text, probably 15 pages, I wan't to be able to add a header at the begining of every page when the user prints the document.
Is this possible with CSS or JavaScript/jQuery????
You can use classic CSS by targeting media using media attribute.
Example:
<link rel="stylesheet" type="text/css" media="all" href="all.css" />
<link rel="stylesheet" type="text/css" media="print" href="print.css" />
Add your <header></header> in your page, position it with CSS, if you don't want it to be included in a browser do:
header {
display: none;
}
in your all.css
And in your print.css:
header {
display: block;
}
Print layouts change depending on the browser, default fonts installed, and any other custom settings used. How would you know where the page divisions are?
Your best bet may be to produce a PDF of your documentation.
