Highlighting Current Page Menu Tab Using HTML and CSS - html

Can someone please offer me some advice?
I'm trying to customise a website and its HTML Nav Menu. By default, the menu already highlights the current tab for all existing pre-built pages.
http://webservices.retrotorque.com
I've added a new page to the website - Website Design - and I've added a tab to the menu for that page. All fine. But I can't find a way of making that tab become highlighted for only when that page is viewed.
Here is the existing code for one of the default tabs, which works fine.
<li class="first <#tag:homesection /#>">
Home
Here's my code for the menu tab I've created for my new page:
<li class="levelone <#tag:webdesignsection /#> ">
Website Design
<li>
My problem is that I can't find where to define:
<#tag:webdesignsection /#>
So I may need to find another solution.
I've thought of another approach:
<li class="levelone active">
Website Design
<li>
This code does work, but only in so much as the tab is always highlighted, whichever page is being viewed.
Is there a way of wrapping this up in a 'conditional'? So that it only applies when viewing the websitedesign page. And I could have a non-active alternative, conditionally set up for when viewing any of the other pages.
Thanks.

i think you should put JQuery there that can addClass and removeClass active from li element.
there is for example
var url = document.URL;
$('#example li a[href="'+url+'"]').parent().addClass('active');

Is it accessible to style button tags to look like links? [duplicate]

This question already has answers here:
Anchor or Button in React SPA?
(3 answers)
Closed 9 months ago.
I see a lot of discussion on the internet about <a> tags that look like buttons, and rules that all links must obey. However, I am confused about <button> tags that are styled to look like links.
I am creating a single-page-app and my navigation component is responsible for rendering / hiding different sections of the website. Only one section would be visible at a time, so I'm treating each section as if it was a unique page with its own route.
My navigation controls are buttons, instead of links. I did this because there is nothing valid that I'm aware of, which I can put inside the hrefs (given that the hidden content is not present in the DOM).
I read on the internet that buttons must have styling to identify the priority of the button, for accessibility reasons. Ideally, I want the buttons to look like links since they behave similarly to links (although not identical).
Are there any accessibility concerns with styling buttons to look like links? Would it make more sense to style these buttons as buttons? If they should look like buttons then what should be the priority? Does it make more sense just to hide the hidden "pages" with css, so that I can turn the buttons into <a> tags and add an href?
Here is the typical markup for single page apps
<div>
<nav>
<ul>
<li>
<button data-name="Skills">Skills</button>
</li>
<li>
<button data-name="Projects">Projects</button>
</li>
<li>
<button data-name="History">History</button>
</li>
<li>
<button data-name="Employment">Employment</button>
</li>
<li>
<button data-name="Contact">Contact</button>
</li>
</ul>
</nav>
<div id="content-panel">
Home
</div>
</div>
The part at the bottom div#content-panel represents the Home page. It will be replaced with the other pages using JavaScript, which will contain the main content of the website.
For those who stumble across this, please don't use <a> without an href, it results in an element that is not longer focusable with the keyboard.
The following fiddle shows this. Try using Tab to focus the links.
You could obviously add tabindex="0" to add them back to the focus order, but this is an anti-pattern and if you ever find yourself doing this it is an indication that you have made a mistake with your HTML.
<div>
<nav>
<ul>
<li>
<a data-name="Skills">Skills</a>
</li>
<li>
<a data-name="Projects">Projects</a>
</li>
<li>
<a data-name="History">History</a>
</li>
<li>
<a data-name="Employment">Employment</a>
</li>
<li>
<a data-name="Contact">Contact</a>
</li>
</ul>
</nav>
<div id="content-panel">
Home
</div>
</div>
If you are building a SPA in a fashion similar to that described by the OP you should still be using anchors <a> for navigation.
There are a few things you should consider:
When each section is shown you should update the URL on the site via JavaScript.
If your site also has Server Side Rendering (SSR) and can function in a limited fashion without JavaScript (recommended as JavaScript does fail more often than you think due to network errors, JS errors for certain scenarios you missed etc. etc.) then the href of the anchors should point to the correct URL.
On SPA navigation it is recommended that once the new page is loaded you programatically set focus on that pages <h1>. You can do this by adding tabindex="-1" to the <h1> (which allows it to receive focus programatically without being added to the focus order of the page) and then using header1.focus()
For an even better experience for people who use a screen reader it may also be beneficial to add an aria-live section to the page with the value of assertive that announces "loading" once a link is clicked. <div aria-live="assertive"><!--add "loading" here programatically when the link is clicked, remove it once the page has loaded--></div>
I have a reasonably long answer with a bit more detail of this technique here that explains why.
To answer the original question finally!
You can style a button to look like a link. However consistency across a site is key.
So make sure that if that is the styling you use for buttons that the majority of buttons look the same.
Also if you make a button look like a standard link then really you should make your links look different to your buttons styled as links.
This avoids confusion as a button has the expectation it will change something on the current page or submit a form, a link has the expectation of changing the page / URL / navigation.
However the advice is not quite the same for a link styled like a button. It has become acceptable that links can be styled like buttons if they are a Call To Action for example. Yet again though, consistency across a site is key for a great user experience.
As stated on MDN Navigation expects to have a links as children. So if you want to prevent any accesibility issue, I suggest you to stick to them, just remove the href attribute and add a type="button" to your a tags.
Anything that looks like something else fools the user. This applies to a link looking like a button, a link looking like plain text, an h1 looking like an h2, a ul looking like an ol, etc. When the user is fooled, the user can get confused or be misled into errors. With a link that looks like a button, for example, the user may press Space to activate it and be surprised to find that it is not activated, but instead the page is scrolled.

HTML - Keeping the Same Item on Navigation Bar for All Pages

I own a website at https://shadowdragonp.github.io/ using a somewhat well-known template called "Squadfree."
On the navigation bar, there are your typical buttons, such as "home", "about", "contact", etc. However, there is also a drop-down menu (not hyperlinked) called "Portals" that takes you to various sub-directories. Although the navigation bar changes depending on the sub-directory, the "portals" menu will always be the same on every page.
The "portals" menu will include more items on the list as time goes on. I do not want to edit all of the pages when I add an item to the portal menu, so I am looking for a way to possibly reuse code for the HTML. All suggestions are welcome!
<li class="dropdown">
Portals <b class="caret"></b>
<ul class="dropdown-menu">
<li>Music</li>
<li>Games</li>
<li>Software</li>
<li>Image Gallery</li>
</ul>
</li>
Add a new html file to a directory something like PortalSubMenu.html. write the code you want to reuse inside of this newly created html document. In your case its gonna be the code your wrote above. Now assign an Id to your navigation bar lets say id="menu". Once done write the following script just before the ending of body tag ''.
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript">
//wait until the dom is fully loaded
$(document).ready(function () {
//adds PortalSubMenu.html content into "#menu" element
$('#menu').load('PortalSubMenu.html');
});
</script>
Don't forget to remove the Portal navigation drop down from man page as this will be coming from separate source. For more info take a look at this Stack Overflow thread Link
I hope you will achieve what you are looking for but I still recommend you to use some server side rather then plain html. because in that case you will generally have a master page or Layout page where you can define things that will stay same across your websites.

Customizing Nested Tabs (HTML/CSS)

Right now at my job, I'm tasked with creating a monitoring dashboard site. I'm thoroughly looking through a lot of different design choices and what my company wants, but all the templates I'm looking at for dashboards aren't formatted the way the company wants: a nested tab feature, not a side bar navigation.
Upon looking through a bunch of nested tab examples, one of them caught my attention which was Zozoui's Nested Tabs. This isn't something I've seen from BootStrap and JQuery UI, so I don't even know how to begin with starting something like this, but I'd like to change a couple of things here and there, like right before the second set of tabs, have a description of the first current tag.
So in short, how do I create my own nested tab feature like Zozoui's Nested Tabs?
You can make a menu and a div for contents when you click a specific tab it's contents should show in that div.do it by jquery or js.
HTML
<nav id="menu">
<a id="item1">item1</a>
<a id="item2">item2</a>
.
.
.
</nav>
<div id="contents">
<div>
jquery
$("#menu a").click(function{
$("contents").html(//something that you want);
});

html navigation page-jump

I am creating a website with navigation that causes a page-jump. But when the page-jump event is executed my page will not load properly, and most content above the called is not loaded. Here is a copy of my navigation:
<div id="navbar-type">
<ul>
<li>BEAR SOUP</li>
<li>FIAT MOTORS</li>
<li>NEWSEUM</li>
<li>TEXAS PARKS</li>
<li>ZACH THEATRE</li>
<li>GUINNESS</li>
</ul>
</div>
How can I fix the code so that the items above the page-jump are visible?
Thanks
you just need to put <a name="bear-logo"> where you want the page to scroll to when the user clicks the link and the same for the others. For example, if you wanted to scroll to the <p> tag below, you could do it like this:
BEAR SOUP
<!--More Code-->
<a name="bear-logo">
<p>Bear Soup:</p>
There doesn't seem to be any error in the displayed HTML. However, you shouldn't need to include the target for inline page anchors.
I assume you actually have the links on the page. For example, <a id="bear-logo"></a>, <a id="fiat-logo"></a>, and so on.
Moreover, the issue you describe seems to indicate that there is some invalid code elsewhere on the page (perhaps JS or jQuery). I'd recommend commenting out sections of your HTML until you isolate the interfering culprit.
BTW, have you considering using a simple jQuery script to flow the navigation to the logos instead of just abruptly jumping to them?

Linking within a page with Bootstrap

I'm very confused about how linking to an element within a page works. I'm learning the starter template for Twitter Bootstrap, and it contains the following code in the navbar:
<ul class="nav navbar-nav">
<li class="active">Home</li>
<li>About</li>
<li>Contact</li>
</ul>
I understand that within the list elements are anchor tags to #about and #contact, but where is the content defined for this? In the example site, the .starter-template div stays the same whenever I click the navbar buttons. What do I have to do to change the div whenever a navbar button is clicked? I tried doing this, but it just made a giant link as you would expect:
<a name="about">
<div class="container">
<div class="starter-template">
<h1>About.</h1>
<p class="lead">#about</p>
</div>
</div>
</a>
Thank you for any help!

The links are placeholders. If you want to keep them the same, such as #about, you'd want to define an element in your page with that ID. For example, make a longer page, and include the following tag:
<h1 id="about">Here's the About Content</h1>
Clicking the link will jump to that spot in the page.
Wikipedia uses this approach to jump to sections in an article. For example, inspect the <span> tag containing the "See Also" text here:
http://en.wikipedia.org/wiki/Twitter_Bootstrap#See_also
However, since they are placeholders in the Bootstrap template, the idea is that you'll put in your own links as you see fit. For example, if you wanted to add a link to Yahoo, you'd enter your own HREF, like so:
Yahoo
Or target any other link in your site.
They're just placeholders. And if you want those targets to exist, you have to create the pages at the URLs they point to.
Such hash links can behave a little differently if you're developing a Single-page Application (SPA), but I think I've covered the simpler answer to what's confusing you. I.e., hash links attempt to jump to an ID within the page, but an element with that ID needs to exist for anything noticeable to occur.
This behavior is built into HTML; it's not something unique to using Bootstrap.
