HTML modules, iframes, and responsiveness

[NumNum]

I am trying to place an iframe in an html module and keep it responsive. It appears none of the html tags I use to keep the iframe from bleeding outside the module when in lower settings than desktop mode.

The iframe contains a index page locally that displays a photo banner slider from jsson as seen here.

Take a look at this:

No luck yet, but I'm still playing around with it.

[NumNum]

Ok, I seem to be able to make it responsive vertically, but not horizontally.

I've tried the aformentioned css tricks without much success.

Any other ideas I can try?

I'll see if a developer can free up a few minutes to take a look.

I started looking at what you're doing, but first I have a few questions. Do you need to use an iframe and include a separate page? Or could you put the jssor banner directly in the HTML module? I think jssor natively supports resizing and Responsive, so if you are able to do it without the iframe, I don't think there would be an issue.

That said, if you use a percentage width on the iframe it seems to resize horizontally better than with the fixed pixel width.

[NumNum]

David, thank you for your time.

Admittedly I do not need to use an iframe, I could use the html module with just the jssor banner directly in the html module, but I am not sure how to link/point to the banner index page.

I did try 100% width but it made no change on responsiveness.

I haven't seen your specific code but are you assigning the div a unique ID or class? You should be doing that whether your are using an iFrame or not, otherwise the div will inherit the relative CSS used elsewhere.

[NumNum]

I'm not 100% sure how to do this. I see the tutorial on https://www.w3schools.com/html/html_id.asp but cannot wrap my head around the rational of it, so i don't understand how it works.

[Wayne Luke]

You add id="mycustomid" to the iframe tag and then you use #mycustomid in the CSS to target it. IDs are more specific than Classes and each ID must be unique on the page.

NumNum, when dealing with iframes, I use FireFox (I am sure Chrome has the exact same option), and right-click some content inside the iframe (in this case your photo) and choose "This Frame --> Open Frame in New Tab".

That opens your https://ragedink.com/banner_slide/with-jquery.html directly which lets you then test the responsiveness by itself. As you can see it is fully responsive and looks great. So that gives you a strong hint that the issue with the responsiveness is _outside_ the HTML in with-jquery.html.

I see a bunch of hardcoded width: 800px. So I backed up to find your IFRAME, and found this:

<iframe id="banner" src="banner_slide/with-jquery.html" style="border: 0; width: 800px; height: 535px; overflow: auto;"></iframe>

That is forcing the iframe to 800 width, and not letting it be responsive. You should try changing:

width: 800px

to

max-width: 800px

then it can't be any bigger than 800px but it can be smaller. You probably want to remove the height:535px altogether.

Thank you, I did try this both with just the max-width and max-width and max-height and it stays in responsive mode even when on desktop when viewed inside the vbulletin tags. I have left it in that format for now. It is fully responsive on its own when viewed in a seperate browser as described.

You can't use fixed widths and heights. You have to use percentages that maintain the aspect ratio.

It should look something like this:


<head> or <headinclude>

<meta name="viewport" content="width=device-width,

initial-scale=1">
</head>

<css_additional.css>

.div1 {

background-color: #FFFFFF;

position: relative;

width: 100%;

padding-top: 56.25%; /* 16:9 Aspect Ratio */

}



.iframe1 {

position: absolute;

top: 0%x;

left: 0%;

bottom: 0%;

right: 0%;

text-align: center;

font-size: 2.0rem;

color: #FFFFFF;

}

.iframecode1 {

background: #FFFFFF;

color: #000000;

font-weight:bold;

font-size: 2.0rem;

padding-bottom: 20px;

}



<div class="div1">

<div class="iframe1">

<div class = "iframecode1">iframecodehere</div>

<p>Description Text Here</p>

</div>

</div>

Disclaimer: I typed this before I finished my first cup of coffee so it may have errors but it should give you the general idea.

Send you a pm with an example.

[David Grove]

Can you post the code that you are using in your HTML module and the Javascript code that you're using to initialize the jssor slider on the separate page?

[NumNum]

Sure;

Html module

<iframe id="banner" src="banner_slide/with-jquery.html" style="border: 0; max-width: 800px; max-height: 535px; overflow: auto;"></iframe>

I'm not sure about the javascript code, do you mean what is in the html index page, or one of the files in the js folder?

[David Grove]

We can start with what is in the html index page.

[Wayne Luke]

What happens if you copy the code from banner_slide/with-jquery.html directly into the HTML module on the vBulletin page?

[NumNum]

if I leave the body tags it displays blank, if i remove the body tags it is also blank.
