Web Languages and Standards





Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services using a wide variety of languages and standards, including the familiar HTML, JavaScript and jQuery, ASP and ASP.NET, PHP, ColdFusion, CSS, PHP, Flex and Flash, but also the implementation of a broad list of standards including XML, WSDL, SSDL, VoiceXML and many more.

I need to create a set of dropdowns that are related to each other in coldfusion. The second dropdown should update itself based on what is selected in the first. Both will draw data from queries but from 2 separate data tables (cities and states). When the form finally submits, want to be able to retrieve id numbers from each dropdown

HTML5 and CSS3 Fundamentals

Build a website from the ground up by first learning the fundamentals of HTML5 and CSS3, the two popular programming languages used to present content online. HTML deals with fonts, colors, graphics, and hyperlinks, while CSS describes how HTML elements are to be displayed.

For some reason, maybe due to schema or lack thereof, my JSON documents are flagged with "Unexpected character sequence in member name".

And also, the member names do not have quotes around them when I first open the document, but then either through process of saving or modifying the documents, the member names get surrounded with double-quotes.

 View: "vAnnouncements",


"View": "vAnnouncements",

I could use some help with this!

I just recently ran "Get Latest" from the TFS, so the double-quotes problem corrected as a result.  But I am still getting the "Unexpected character" thing.

I am getting frequently below err message  while watching videos.
The browser I am using is Chrome.

please advise how to fix this issue.

I want to query a database and include the output in a table on a Wordpress page. I have the PHP code that queries the database, and it works correctly, but I can't figure out how to output that onto my Wordpress page.

I've looked into several widgets, like InsertPHP, but I can't figure out exactly how they work.
I found this page:


And want to use


on shared hosting website with hostgator.

I copied the html to a file called index.htm
the css text as a file called index.css
and the js text as a file called index.js

When I go to the website, I get a blank page.  If I show source, I DO see the HTML, so the code is there.

But don't know what I am doing wrong / what I need to do (I really don't know web design. My experience is really front page from YEARS ago : )

redis used as cache data in at some point if we want to persist to SQL/No SQL is there a straight forward way?
I am just looking for a simple, light jquery plugin. I want to load a popup box/window on my home page that displays this months specials/discounts. I don't want it to be intrusive, so I want to be able to control the placement. Ideally it will pop up from the bottom right portion of the screen. I also want to be able to choose the look and styling.

I cannot even believe the trouble I had with trying to google what I need. All I could find were modals or tooltips or onclick or windows that were fixed in the center of the screen. I tried several different wording on searches and went several pages deep in results, and cannot seem to find something that fulfills those requirements.

I figure someone on here might know of something off hand that they could recommend. Thanks!
Some random examples:

<!DOCTYPE html>

What are these for?  What is their origin?

Can these references be viewed?  For example, the one for HTML4 I can go to the strict.dtd page, but what about the one for HTML5?  Or are they proprietary / confidential?  How do web programmers take advantage of them?

I am trying to put together some pertinent questions in regards to our corporate website, in terms of technology, hosting, support, roles & responsibilities etc. This is to assist in an independent review of the website by a 3rd party from both accessibility, performance, security etc. Can you suggest some relevant 'fact finding' questions that if you needed to understand the setup of a website, and its hosting, and all the various technology components used to develop and maintain the site. It is not something I have ever had responsibility for, so having some queries in order to get a better understanding would be most useful.
Explain how TypeScript fits into Angular?

I coded Angular 4 and am pretty sure I used TypeScript. But, I can not recall exactly where.

Please refresh my memory.

I am trying to quantify risks with the current 'management' and roles & resp[responsibilities of our websites 'content management system' (concrete5). I have never administered a content management system for a website before, but my overall understanding on permissions is there is an admin level role which allows overall control, and then there are author level roles, which allow a number of users to edit content on specific pages or areas of the site. My concern, from a contingency perspective, is we only have 1 officer with admin permissions on the CMS, and the others are only author level roles. The concern being if the 1 current admin was unavailable for example ill health for a few months, what would grind to a halt in terms of the overall CMS management?

Back to the 'I have never administered a content management system for a website before' - if you are a CMS admin, what activities/maintenance/monitoring requires admin level permissions in a solution, or put another way, if nobody logged in as an admin for numerous weeks, what could the knock on effect be? I was also hoping to establish some standard maintenance checklists that the CMS admin has to perform, so if they were unavailable another officer could pick up their duties and would have an easy 'how to guide' on which to follow. Ideally supplemented with formal training.
i am trying to manually write some css that simply involves a banner image with some text overlaid. Turns out it's not a simple as I thought. I'm only onto the second media query, and I'm running into trouble. Mostly because I'm stuck in the intermediate level of css and have not yet advanced to expert.

Here is the page: https://www.stadriemblems.com/products/enamel-pins-test/
The css is here, but you can also find it by viewing the source of the page: https://www.stadriemblems.com/static/css/enamel.css

Right Now it's only going to display in the initial desktop viewport size, so you son't be able to help me if you're on a mobie device.

Here are some problems I am running into right off the bat.

I want the text to be centered vertically. It sort of seems like it's working, but it isn't exactly. See the two image attachments for how it looks on my 1440 monitor and how it looks on my 1080 monitor.

That also leaves the issue of height. I have the height set to be a static 1440px at the largest size, but because there is a background image, and without a set width, there's nothing to expand the div. I have the width set to 100% and the background set at "contain" but I guess all those things aren't compatible. I guess I need some advisement as to what to do in this situation.

Basically, my end result is that for all media queries, I want the image to always be 100% width with a proportional height, and for the text to always be vertically centered and fit …
Can anyone explain the best practices in regards to link labelling specific to usability/accessibility best practices. A 3rd party who do some basic maintenance of our website have numerous image based links on the homepage which simply state "click here". If you hover over the link it does give a bit more detail on where the links takes the user but I am still not sure that is sufficient, and the label itself should be meaningful, but I am trying to emphasis the risk in them using this kind of practice. I have seen these guidelines, but I cannot find anything specific in WCAG to link labelling best practices to assist users with disabilities e.g. visual impairments. I want to draw out the types of user this type of configuration could impact - to make them improve and use more appropriate labelling.


Just saying it 'looks poor' isn't having much weight in the argument.
Need a YouTube based webinar, with chat service

I need to create the MP4 of a live webinar, where I use OBS to live stream myself to YouTube, with my green screen replaced with a professional looking image. But I need one to many chat services.

So, how much I do this?

I wish I could use a comprehensive webinar solution, but they either do not support the green screen technology (WebinarJam) OR they are too expensive (GoToWebinar).

So, my solution is to use:

1) OBS for green screen removal
2) Live OBS stream to YouTube
3) YouTube handles audio

But I need a chat service my attendees can use to submit comments and questions.  


Hi Experts,

I have the following code which works fine for Win8 OS, while in Win7 it gives me an error, "cannot connect to the server".

Someone already helped me set this up in one Win7 pc, however now I need to move this over to another pc.

            Set objHTTP = New WinHttp.WinHttpRequest

            objHTTP.Open "POST", url, False
            objHTTP.SetRequestHeader "Content-Type", "application/x-www-form-urlencoded"
            objHTTP.Send "grant_type=client_credentials&client_id=MyID&client_secret=MySecretID"

Given the below soapclient - how can I a) check the version of tls that it is using, and b set it to 1.2 if it is not using that already?  I had assumed the browser I was using would control that side of things, but just want to double check!

//Create the client
$client = new SoapClient($url);
$datetimestamp = date("YmdHis");

I have a web page that displays and plays my voice messages stored elsewhere on the web. I am having a problem with the Chrome built in audio control running in an iframe. Here is what it looks like:audio control in iframeHere is the code:
<a href='https://api.twilio.com" . $recording->uri . "' target='newframe'>Play</a>
<iframe name='newframe' frameborder='0' height='150' width='300'></iframe>

Open in new window

As you can see, there is a big black area above the audio control.

I can wrap the iframe in a div to round the corners:audio control in iframe with round cornersCode:
<div style='display:inline-block;height:150px;overflow:hidden;border-radius:27px>
<iframe name='newframe' frameborder='0' height='150' width='300'></iframe>

Open in new window

But if I try to reduce the height of the iframe and div, the audio control just gets smaller and I loose the time slider"shorter iframeCode:
<div style='display:inline-block;height:54px;overflow:hidden;border-radius:27px>
<iframe name='newframe' frameborder='0' height='54' width='300'></iframe>

Open in new window

I tried just reducing the height of the div or iframe without reducing the other but then the audio control is out of the frame.

Any idea of how to reduce the height of the iframe without changing the audio control?

I am thinking of using the HTML5 audio control instead (as in the sites below) but I am not sure how to load and then play a new message from the <a> link.

Hello experts,

Could you please advice on this.
Thank you very much in advance for your feedback.

Hi everybody.
I really don't understand how to change the overlay background color in this template: https://colorlib.com/preview/#amado.
I mean: if you hover the mouse on products, a dark semi-transparent overlay appears. The template uses a scss file. In the index a fiola called style.css is linked, but that file is empty and with developer tools I see all styles are set in  style.scss, but I'm not able to find the value that I have to change. I confess I'm totally new to sass, scss.
I post here the scss file:
@import 'theme_color';
@import 'variables';
@import 'mixin';
@import 'responsive';
