Bootstrap 4 menu - menu

I'm trying to make a two-lines menu with bootstrap 4, and I found some examples on the web:
https://www.codeply.com/go/DpHESPqZsx
https://www.codeply.com/go/cxXqBnGrPx
In the first example they use "div class='navbar'" to create the menus.
<div class="navbar">...</div>
In the second example they use "nav class='navbar'" to create the menus.
<nav class="navbar">...</nav>
Which is the correct way? Which one should be used?
I have another question. Why do they NOT use the bootstrap grid with the rows and columns? When should you use it?
Thank you very much

Div and nav are similar element, in terms of what they do. However, nav is better in this situation because you want to have semantic markup. It is because of SEO and more readable for developers.
And why they are not using grid is probably because they haven't implemented it yet and should be coming. Their grid system is done with flex currently, but should change. And CSS Grid does not work that great with IE11.
You should use Grid when you feel that it will be easier to structure your site. It's a great tool, and combine it with Flex is so easy and comfortable

The difference is that a div has no meaning and a nav Element has a semantic meaning (indicating that there is a navigation). You can remove every div and span from a website and have no difference about the semantic structure of a page, every other element has a meaning: For example, states that there is the main content, says here is the header-part of the site.
These parts tell for example search engines what's on a site. So if you have the text "Stackoverflow" in your Element somewhere, google (and other search engines) know that you have a stackoverflow link in your navigation. If you have it in your Tag, you probably have a text about stackoverflow.
Keep in mind: These are some simplified examples.

The html5 nav tag has semantic meaning.
Please follow the Bootstrap docs. The grid (row>col) should not be used in the Navbar as it's not a supported component. Using the grid inside the Navbar will through off alignment, spacing and the responsive behavior controlled by the navbar-expand-* classes. I'm the author of both Navbar examples from Codeply you posted.

tabulator paginationElement styles problem

I have a question about paginationElement in Tabulator.
As per tabulator documentation, i created a DIV and used paginationElement in Table setup to render the paginator in the DIV. Well, it works. But with a drawback, no styling works, no colors, no highlighting of current page. So it is kinda inconvenient.
Is there a way to resolve this?
Otherwise, i am really happy with Tabulator! Thank you for the great work!
Cheers
You might have to style the pagination footer by css as the location of it has been changed by paginationElement.
This is because all of the table styling is based around the pagination element being inside the table.
Moving it outside the table will mean you will need to apply the styles yourself. The classes that denote that you are on the current page etc will still be applied, you just need to tell the browser how to style them.
The Styling Documentation contains more information on the classes used by tabulator and how to style the table

Kentico Widgets :: Matching fields with HTML structure of Web Part

I really hope I'm making sense with this one.
I'm trying to create a widget from a custom webpart that I created. It's nothing special at all as you can see:
<h3>Header</h3>
<p>Intro Copy</p>
<ul>
<li>List item one</li>
<li>List item two</li>
<li>List item three</li>
</ul>
I now want to be able to create a widget from this and create new fields that will be used to populate the above DOM. What do I need to do in order or do this.
In an example I saw for the demo site, they populated the bg image with:
style="background-image: url('{% ResolveUrl(PathToImage) %}');"
That was however done on the front facing part of the CMS and I'm trying to do it within the solution.
Any thoughts?
It's all in your layout or code behind. Your layout can have that code (but in ASCX format) and it will work just fine. OR you can add literal controls to the page based on the fields and what the user has entered.
Doing it in your layout is more restrictive and specific to that one application but allows you to use multiple new webpart layouts. Using the code approach allows you to be more dynamic but doesn't allow you to use the built-in layouts of the webpart/widget.
I would just use the Transformable Web Part in the Marketplace...it does exactly what you want it to do. Create a custom web part, and you use a Transformation to style the Web Part Properties into the DOM elements.

Reason why i built it!
I've done something similar in the past, using what I call generic web parts. I wrote a blog on it last year - it might help out with what I think you're trying to achieve:
http://www.mattnield.co.uk/Posts/Show/generic_web_parts_for_rapid_development
Why are you choosing to go with Widgets? If you want to access any field inside the transformation within the web part it's feasible by the same way as you define in inbuilt web parts.
If you want to perform any function like onload etc. then you need to use kentico API to access any data.
If you provide more insight on what is required, I can help further

Display content part in Orchard

I would like to be able to specify exactly where a ContentPart is rendered in a view.
For example, in my Content.Summary.cshtml I want to wrap my title and first image from the gallery (I'm using ZenGallery) in an anchor tag. I thought I would be able to do it like this but the gallery template is not rendered.
<a href="#Url.ItemDisplayUrl((IContent)Model)">
<h2>#Model.ContentItem.TitlePart.Title</h2>
#Display(Model.ContentItem.ZenGalleryPart)
</a>
But if I do the following then the gallery template (ZenGallery.Summary.cshtml) is shown along with all other parts.
#Display(Model.Content)
I understand that the recommended way to do this is probably using Placement.info, is that right? But this way makes more sense to me and would allow for more fine grain control of the end markup. How could I achieve the markup I'm looking for?
This should give you a pretty good start on doing precisely what you want: http://weblogs.asp.net/bleroy/archive/2011/07/31/so-you-don-t-want-to-use-placement-info.aspx

How Can I Use Shadowbox to Extract Text Only from Webpage?

I have an article set up in Joomla that displays Terms and Conditions for the site users. I would like this to show up in a shadowbox when a user clicks a link. Here is the current anchor text example:
Terms and Conditions
This works out great for displaying the entire web page, but what I would like to do is just display the article text on the page (plain with a white background). Is this in someway possible with shadowbox? If so, how?
If I'm understanding you correctly - you want to suppress the modules and other periphery from your 'page' when it is loaded in the shadowbox.
Add ?tmpl=component to the url of your link.
You can do this with a div element and css shadow effect.
How to show/hide div is explained here:
http://www.randomsnippets.com/2008/02/12/how-to-hide-and-show-your-div/
How you can add shadow is explained here:
http://placenamehere.com/article/384/css3boxshadowininternetexplorerblurshadow/
I believe there are some components to do this - but you may have to get creative to do it without pulling the whole page with an a href tag.
In the database there's a particular area that holds that specifically and you could write a little query to just pull that information specifically and put it in the shadowbox, but what that query would look like I'm not sure.

Web accessibility and h1-h6 headings - must all content be under these tags?

At the top of many pages in our web application we have error messages and notifications, 'Save' and other buttons, and then our h1 tag with the content title. When making a web application accessible, is it ever acceptable to have content above the top-level structure tag like we do here?
As a screen reader user I don't like content above the main heading. Normally I navigate by headings so would miss the error message. A better solution is to output an h1 heading above the error message, then leave the rest of your headings in tact giving you two h1 headings.
Yes (you can put stuff above them). The H simply means Heading. It's a question of what the heading relates to I guess.
My only caveat is, H2 shouldn't really be above H1, and H3 Shouldn't be above H2. But I don't think it's an actual rule.Websites have menus, warning, notifications. It's acceptable to put them above the rest of your content. I don't see how it would affect accessibility as long as your content is ordered logically. Look at the page CSS turned off. Does it look logical? That's the most important part of accessibility.
Although some people do go that extra mile and have the menu as the last item in the markup and use CSS to bring it back to the top. Personally, I find that solution counter productive. The menu is still important, it belongs at the top of the page.
Yes, just consider it is in that order that the user will get the information. So, if you just did an operation it sounds like a good idea to get any message related to it as the first thing. If it is a notification that appears on any page unrelated to what you are doing, I wouldn't put it above, as it might be a little weird.
Also you can use a text browser that doesn't use styles, it should look like a document with appropriate headers.
Heading tags are used to indicate the hierarchy of the content below it. You should only have one h1 tag and it should be the first content to appear on your page (this is usually the name of the site). Also, you shouldn't skip heading tags when drilling down through different tiers of content.
In your case, you can still use CSS to position items above the h1 tag as long as it is in the correct order in the html.
I assume the elements above the heading are used by JavaScript. In that case, it's preferable if they are created by JavaScript, not included in the source of the page.
To return to your original question, it is probably best that they be at the foot of the page. However, if they are hidden using the CSS "display: none;" or "visibility: hidden;" properties then they will not be seen by most (perhaps all?) screenreaders or by many other assistive technologies, and so should not be an issue. I've written a fairly detailed explanation of why accessibility technology ignores such elements.
Of course if somebody disables CSS things are going to look pretty messy. If there is content on the page that can be used even when CSS and/or JavaScript are disabled, then putting those elements at the bottom of the page will at least make things less cluttered.
