Websites like Wordpress and Tumblr allow designers to create themes that users can select. In general how would you architect a website to be flexible enough to allow custom themes for users?
Take a look on how Django does it. Django uses a Model-View-Controller-like approach in which you use views to populate a context, and then use that context to process a template. Note that Django has its own MVC terminology.
For example, if we say that our context reads as follows (in pseudo code),
author = 'mntnoe'
title = 'My Title'
content = '<p>This is my content</p>'
we could use the following template:
<h1>{{ title }}</h1>
<div class="author">Author: {{ author }}</div>
<div class="content">
{{ content }}
</div>
Now, you are free to replace the template (or collection of templates) with another one without affecting how the site works.
Seperate content from formatting by using proper html and css. That means using css files for the style rather than inline style inside the html.
You can make several css files (themes if you wish), and switch between them using javascript.
Let your serverside technology of choice simply generate easy to adjust, by css and images, html. A great site of examples is http://www.csszengarden.com/. It emits the same html every time but uses different css and images to style it. Take a look at the html they generate to get ideas.

We're using the WordPress REST API to power a static site. The site is "headless" in the sense that we don't use a WordPress theme; we rely on the content being exposed via the REST API.
Some of the default Gutenberg blocks - the Buttons block for instance - have styles with hashed class names associated with them that don't seem to be exposed in the API. This would be kind of ok if the class names were predictable but, since they aren't, we have no way of providing the styles on our end.
If we do render the blocks in a theme, the styles are rendered in the footer
Here's an example of the style block for the default Buttons block looks like in a WordPress theme
The Rest API endpoint exposes the markup in content.rendered (including the classnames) but no styles
Is this expected behavior for using Gutenberg and the WordPress REST API? If so, is the correct solution to expose the styles via a custom field (for lack of a better term) on the API?
The unique id (hash) in the classnames are randomly generated each time the blocks are parsed, even when directly calling the REST API. Unfortunately, the inline style attributes like .alignleft are absent from the content markup in the REST API. Being a REST API, it makes sense that style specific information isn't included; this keeps data and presentation of the data separate. It also prevents bloating the API by including style-specific information that would be rarely used outside of WordPress theme.
In your scenario, if you wish to style the resulting HTML content without worrying about the unique id, I'd suggest using css partial selectors, eg:
div[class*="wp-container-"] .wp-block-button{
...
}
Alternatively, as you mentioned, its possbile to extend the REST API to include the styles. While I haven't built a working example of this for styles, when blocks where introduced I ended up extended the REST API to include extra meta data. I'd suggest looking at render_block_data to handle adding in the styles into the content.
Eg. For the buttons block, the serialized content stored in the database as:
<!-- wp:buttons {"layout":{"type":"flex","justifyContent":"center"}} -->
<div class="wp-block-buttons"><!-- wp:button -->
<div class="wp-block-button"><a class="wp-block-button__link">Hello</a></div>
<!-- /wp:button --></div>
<!-- /wp:buttons -->
By using parse_blocks() you can obtain all the block properties into an array and get style information that way. I think this approach is do-able if you just add the generated classnames and not the inline styles. I am keen to know if you find a better way...
I am a beginner in laravel, and having some trouble in laravel CSS layouts.
I have multiple links in my web, for example:
testing.com/main
testing.com/AboutUs
testing.com/ContactUs
which I used a layout stored in /layouts/main.blade.php in the views folder.
Inside the layout, I wrote all the css link that is based on the public folder.
For ex:
<link href="stylesheet" href="/css/styles.css">
And it works fine on all the links except for the ones with sub-links, for example:
testing.com/main/Clients
testing.com/main/Solutions
The CSS seem to have dissapear when I navigate to sub-links.
Am I not properly declaring the CSS in Laravel? The CSS works perfectly when it is not a sub-link.
You should use the Laravel helpers to add assets to your views as they generate the correct URLs. Either use URL::asset('css/styles.css') or asset('css/styles.css') if you need to get a link to an arbitrary asset. Alternatively, you can be a bit cleverer and get Laravel to do some extra hard lifting:
{{ HTML::style('css/site.css') }}
{{ HTML::script('js/site.js') }}
{{ HTML::image('images/logo.png') }}
These will write your HTML for you as well as generating the links to the assets.
You can use
asset('css/styles.css')
It's work fine with me!
Typo3 provides option to add multiple images to a page content, but all the images are wrapped under some default <div> tags. I want these images to be wrapped under <ul> and <li> tags instead and giving my own custom CSS ids and classes to it.
There are not many resources on TYPO3 for me to approach this issue. Can TYPO3 allow to use custom tags for the page content elements?
UPDATE
From Jost's answer was able to get my images displayed, but how do I split the image details?
My each image will have title, alt-text, image-path and image-link. Now, using TypoScript how do I retrieve this, because each details has to go in separate tags.
Check the TypoScript object browser. There you will find the object tt_content, which contains the rendering definitions for content elements. The rendering definition for images is found at tt_content.image.20, for example
tt_content.image.20.imageStdWrap.dataWrap = <div class="csc-textpic-imagewrap" style="width:{register:totalwidth}px;"> | </div>
The default definitions given there are usually provided by the static TypoScript of CSS-styled-content. You can overwrite them in your own TS, but when updating to a newer TYPO3-version, the default template may change, which could result in additional wrappers.
Update
Most content rendering in TYPO3 is defined in the TypoScript object tt_content. You can browse all TS-objects that will be used on a page by selecting the "Template" module and the page in question, and then choose "TypoScript Object Browser" in the selectbox at the top of the window. To understand what that stuff means, knowledge of TypoScript is necessary (Tutorial, Reference).
You can add your own TypoScript, which may override existing settings. You can do that in the Template-module too, but usually this is done by creating a file containing the script somewhere in the fileadmin folder and including it from the Template module.
The above enables you to edit the markup of the page. (Additional) CSS is usually defined in external files, that are included by a PAGE object (see the reference about that).
This post is a bit older but I want to add the following:
If you want to understand how the different content elements are wrapped, you may have a look into the css_styled_content extension. I assume that you have included the "Static Template (from extension)" in your main Typoscript template.
You can find the setup.txt here:
typo3/sysext/css_styled_content/static/setup.txt
There you´ll find the line Jost mentioned in line 860 (TYPO3 version 6.1), for example. And of course a lot of other definitions, too.
But check to read the documentation and tutorials on typo3.org.

Is is possible to define regions in the template, that would pull content from the page?
Let's say I have in my template the following structure:
<div class=sidebar></div>
<div class=content></div>
And from the page content, I would like to pull some html content to the sidebar, and other content to content div.
Is this possible?
With Swig as the Engine
Yes, this is possible. Seehttps://github.com/assemble/boilerplate-swig, in particular, this example, which shows how to use {% macro %} tags to accomplish what you're asking about.
If you want to use Swig, be sure to look at the readme as the assemble-swig repo as well. You have to register swig as the current engine in assemble:
assemble: {
options: {
engine: 'swig'
}
}
With Handlebars as the Engine
If the sidebar content will always be the same, on every page then you can use partials for this. Even if the URLs or active classes change on each page, this should work.
However, dynamic content using template or "block" inheritance, e.g. extend can be achieved with Handlebars helpers.
But since layouts are used with assemble this is a bit trickier to do with "out-of-the-box" helpers. To clarify, just about any helper I can think of will work great with assemble out-of-the-box, except for this - specifically because of how layouts work.
My suggestion is that you add to the existing feature request(s) for this on assemble and/or the handlebars-helpers project to add your use case and thoughts on what you want to achieve:
https://github.com/assemble/assemble/issues/38
https://github.com/assemble/handlebars-helpers/issues/16
#jonschlinkert You should update assemble's documentation, cause start with Assemble isn't so easy and a lot of things are little hidden.
So Luis, you can try this method, which currently works great for me too!
Assemble: Multiple points of content insertion in layout?
I am working on an Ubercart installation on a Drupal site we are producing. Everything is going smoothly, but I am now trying to setup the order page template (uc_order module), so that the frontend developers can style it up.
The page is the one you view when you go to user/[UID]/order/[ORDER-ID].
I understand how to use hooks, preprocess, theming and template functions within Drupal, but currently I cannot see a way of changing any of the markup on the "order panes" that make up the page. It goes without saying that I don't want to touch any of the module's code.
So, one of the pages is the 'Bill To' address pane:
<div class="order-pane pos-left">
<div class="order-pane-title">Bill to: </div>
Name<br>
Address<br>
Town<br>
Postcode<br>
</div>
Essentially I would like to put a class in the div, so that it looks like this:
<div class="order-pane pos-left bill-to">...</div>
<div class="order-pane pos-left ship-to">...</div>
<div class="order-pane pos-left payment">...</div>
<div class="order-pane pos-left comments">...</div>
...
I just cannot see a way of doing this.
Any help would be much appreciated.
Have you checked the latest version of UC? The release note states:
The biggest change, though, is that order invoice templates now use the theme system to allow customizations. Instead of altering the module files directly, it is now correct to override them in the theme, just like node and page templates.
...and if I am not mistaken (a few months have passed by since I worked with UC), the invoice IS the page displayed by the URL you provided.
If my memory failed me (I haven't a UC installation handy to verify myself), a possible workaround (admittedly far from elegant, but still allowing you not to change the module's code) would be to alter the HTML with jQuery once the page has been loaded.
A more hack-ish workaround would be to maintain your own page callback for that URL, and just alter the menu definition in the UC code [yes, it's still hacking the code, but in this case you just need to modify one line in the UC code, and can maintain your code in a separate module].
HTH,
Mac.
You can create youre own panes or a single pane for everything, look up hook_pane, or you can insert the classes using jquery.
