HTML comments not visible in Outlook - html

I’m using comments in some HTML code to make identifying elements easier for future updates. The HTML is being used to create an email in Outlook.
When I comment using
<!— MY COMMENT —>
it is not visible when I view the email source! I can see the HTML code, but the comments I have added are not visible.
The email is composed using a VBO through Blue Prism (not sure if it’s relevant but adding for clarification).
Can anyone shed any light on why this could be happening and how I can make these comments visible.
Thanks!

Keep in mind Outlook messages are shown and edited using Word, so it converts the original HTML to its internal representation and then back to HTML. See if hidden text would work any better.

Rendering HTML template in Email clients

I have HTML template completely written with div, a, img, button elements with inline CSS styling. It renders perfectly in HTML editors but not in Email clients. Should it be completely written in table form for Email clients? Here is my code:
Look it on JSFiddle
I believe your particular question is dependent on which email-client you are targeting. It would be helpful if you could specify which email-client you are looking to use, as well as which parts of your html are not working, because certain email-clients may not support certain parts of your code.
For example, as defined here,
Outlook has the following problems for rendering HTML:
Outlook does not “understand” HTML bulleted list tags
Outlook uses Times New Roman as the default font
Outlook may add a page break to an email if it exceeds 1800px
Outlook cleans up paragraph and margin spacing
Outlook does not support background images
Which you may be able to fix by using specific techniques, such as, as you mentioned, wrapping with tables. I found a link here that may be helpful if you are trying to resolve the rendering on Outlook.
If there is another specific email-client you need to target, there should be posts on stack overflow or on the web for resolving them as well.
Good luck!
You do have to use tables in email HTML and then use CSS and formatting to mask it. Here's a handy guide you can use for email HTML.

Gmail cleans html on email forward?

I've noticed that when you forward an html email from Gmail (not sure about other providers), the html structure changes in the process. The forwarded html loses all the ids declared inside the original html, also some other 'cleaning' happens on the html too.
Can anybody explain why this happens or if it's possible to avoid? Or is it totally dependent on the smtp provider?
I have an app that monitors emails on a specific inbox and tries to parses it, but as I said when the user forwards his email to this inbox (from gmail), the email html structure gets cleaned and my code can no longer parse the html because a lot of the ids are gone.
Due to this, I have to find a new way to parse what I require from the email, like using regular expressions on the plaintext section of the MIME message.
I've searched about this matter and I couldn't find any single piece of information.
Gmail strips head tag and Ids and classes on pre-processor. That means when you forward or reply, to gmail, these items never existed so are not included on reply.
As Gmail removes head tag, id, classes and more, the best way is to use inline CSS style.
Tip: An inline style loses many of the advantages of a style sheet (by mixing content with presentation). Use this method sparingly.

How do I merge 2 HTML documents and their styles correctly?

I'm the author of an email client and one of things I'm in the process of doing is adding support for HTML editing. The editor itself it build upon a HTML rendering control that I've written from scratch, however it supports most HTML and CSS fairly well. The issue I'm having is formatting the reply to HTML email with the user's reply template, which is also HTML (with a different style sheet). So cleanly merging two HTML documents with their own styles without either of them being messed up by the other document's styles.
When the user replies to a HTML email, I parse out the content of the tag and put it into a that forms part of the reply. That div's style shows a line down the left margin to inform the user that it's quoting the original email. Gmail does the same thing. Anyway the styles from the HTML block as saved separately and then insert into the head part of the new document.
What happens of course is that if the original email defined a style for say a link, that style affects all the links outside the original quoted area. So things like my signature at the bottom and the From/To header rendering that is part of the reply template all get that styling from the source HTML.
I'm wondering if there is an easy straight forward solution to containing all the original styles to just the quoted part of the document? Something like namespacing? Or limited scope styling?
The solution I've come to is to add all the incoming styles from the multiple documents to a global style sheet. Styles are matched by first checking the count of properties is the same, then enumerating each property and comparing it's value. This basically gives the software a minimum number of styles to correctly render the content. It could be really slow in a pathological case but so far it's working well in practice.
As an aside, recently I've noticed a lot of email clients striping all the style out of replies. Which to be honest seems like the cheap and nasty solution to the issue. Even if it does give a consistent look.

Red Font (In Firefox) <img> tags in HTML not seen by JSoup

EDIT: Self-Answered. JSoup does indeed find all image tags.
I'm trying to scrape something off https://www.flickr.com/explore and I ran into a problem.
In the source code, the main images on that website are written in red font, and they don't get found by my JSoup select method (or with the getElementsByTag method). It would be much easier if you guys went to the website and checked the source code yourself because of formatting issues but I'll try to include the bare minimum here.
EDIT: I just tried viewing the source code through chrome and IE, and the image tags are not red, so I'm assuming it's firefox formatting. But the question remains, JSoup doesn't see those image tags. (Second edit at the end of the post)
EDIT 3: Removed my pasted code to put this print screen in: http://i.imgur.com/o8fNPnZ.png
Notice how the red blocks are the main user uploaded images (that I want), and you can see other img tags that are not red (but those are only things like tiny logos). When I run the code
Elements imageElements = doc.select("img");
and then print it, I get all the tags that are not red.
I'm not very experienced with HTML or CSS, is there something specific that I don't know? Or is it something in my code? Is there a way to retrieve the "red" font images as well?
EDIT 2: OK so I narrowed it down to red HTML font in firefox being an error of some kind. If I hover over it, it says: No space between attributes.
Now I'm a little more confused since flickr is a huge website and it obviously still works since I see the images. Can this be some sort of "anti-scraping" thing they have going on? Is there still a way for me to download the images?
Answering my own question.
I was mistaken, JSoup does indeed find ALL the img tags. I'm not 100% sure where my mistake was since I saw it yesterday and have changed my code since then, but I'm assuming it was my misuse of .select which would exclude those images (my code in this question was simplified for argument's sake).
I'll leave this question up because it might help someone else running into errored HTML in source code since there are a few helpful tips in the comments

HTML Code too long

I have a quick question I have an HTML Signature for may emails. I need to implement them into my exchange server`s transport rules.
Unfortunately the limit is at 4096 characters and my HTML signature is 8950 Characters.
I would like to know if there is an HTML code that will access a public URL and then gets the necessary HTML content from the public URL, so that I can circumvent the limitation.
Thanks for your help
It should be normal HTML stuff i guess, Office 365 Microsoft is what I am using.
I have my company logo comming from the server, does this mean Gmail user will not be able to see my logo? I am bringing it in via a URL
every time I try to place the HTML code it shows the actual signature, any idea how i can change that?
regards
Its difficult to code for HTML emails as different email clients deal with html emails in different ways.
You could
1. Reduce spacing used in html tags, inline styling.
2. Modify markup so as to use lesser tags
Best would be to reduce the signature content, remove unnecessary parts.
In case you cant do, so you could use a image of your signature & link a image tag.[NOT RECOMMENDED] This wont work in gmail since it blocks image loading by default.
Maybe posting your signature might help?
