recently I decided to create a Tumblr using this theme
I'm a Firefox user, and I noticed that this theme slows down the browser a lot. After some investingation and asking, the culprit seems to be the possibility to add an animated particle background that, even when disable, causes high cpu usage.
This particle function is inside a script called "s.js", that contains other part of the theme.
Is there any way to clean up the code from everything related to this particle background, and still leave the theme functional?
Thanks
OK
Option 1:
Search for all of the libraries that are being called from the js file you linked to s.js apart from ParticleJS.
Images Loaded: https://unpkg.com/imagesloaded#4.1.3/imagesloaded.pkgd.min.js
Isotope: https://unpkg.com/isotope-layout#3.0.4/dist/isotope.pkgd.min.js
Infinite Scroll: https://unpkg.com/infinite-scroll#3.0.2/dist/infinite-scroll.pkgd.min.js
Fitvid: https://cdnjs.cloudflare.com/ajax/libs/fitvids/1.2.0/jquery.fitvids.min.js
Photoset grid: https://cdnjs.cloudflare.com/ajax/libs/photoset-grid/1.0.1/jquery.photoset-grid.min.js
Magnific Popup: https://cdnjs.cloudflare.com/ajax/libs/magnific-popup.js/1.1.0/jquery.magnific-popup.min.js
Caveat, these are specific versions of each file and you could run into compatibility issues, if you need to link to a specific version.
Combine all the code from these files into a single file, then you could run it through a minifier: https://javascript-minifier.com/
For this solution to work you also need somewhere to host the file somewhere.
Option 2:
Link to all of the above files individually in your template. For example before the closing <body> tag you would need to add
<script type="text/javascript" src="https://unpkg.com/imagesloaded#4.1.3/imagesloaded.pkgd.min.js"></script>
... then add each of the other scripts. There may be a dependency order to these also, hopefully they are the same as in the header of the s.js file.
The drawback with this is instead of making a single http request to return a single js file, the template will request 6 separate js files (so this might be slower than the current system you have now).
Option 3:
If you can't host the file somewhere, you would have to actually copy the code from each js file into your template.

Here is a link to my site, http://johnathonpowers.bigcartel.com
Trying to play around with images on my product pages...well actually created a test page.
Unable to figure out a few things:
Where does one host a jquery file?
Do I need to have the jquery src for both jquery.min.js (many use the one hosted by google, if I am understanding any of this correctly) and jquery.elevatezoom.js?
If I end up not liking the zoom is this still an appropriate way to have a large image with small thumbnails beneath (perhaps I will explore how to click on the big image to open a full-screen version).
Should all my pictures be the same size? Right now I have square format photos and rectangle...it might end up looking horrible.
Do I put any code into CSS or just the layout and the specific page I want the images to take place?
Will these images replace the ones I upload through bigcartel's system?
There is already a jquery entry in the layout...do I just add to the end of this same section the additional src?
This is what I added to layout:
<script src="http://s000.tinyupload.com/index.php?file_id=24823496361920795072" type="text/javascript"></script>
This is my test page:
<img id="zoom_01" src="http://i.imgur.com/1L86Fcms.jpg" data-zoom-image="http://i.imgur.com/1L86Fcm.jpg"/>
$("#img_01").elevateZoom();
<head><script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js" type="text/javascript"></script></head>
<img id="product_zoom" src="http://i.imgur.com/1L86Fcms.jpg" data-zoom-image="http://i.imgur.com/1L86Fcm.jpg" class="fade_in">
Thanks again for all the help and honestly probably biting off more than I can chew. I just wanted to play around with it and see if it would work/was something I liked, but seems like I have gone down a rabbit hole into a whole other world, way above my rudimentary html skillset.
Here is where I first saw the jquery stuff:
Can I integrate an Internal zoom on my products in my big cartel store?
The best place to host your javascript files is on a server that you have control over -but if you don't have any webspace, you can easily host files with a service like Dropbox or Google Drive.
The Luna theme you're using already loads jQuery in the <head> portion of your Layout, so you don't need to include that script again (and you'll get errors in your browser's javascript console if you try).
Since you're using a separate image zooming library that has a bunch of custom CSS, you'll probably want to have your CSS file hosted on a separate server as well. It's a good idea to put any files you're including in the Layout section, following the same format as the existing theme files.
It looks like the javascript file you're hosting on tinyupload.com is just bringing up a download page instead of actually loading the javascript content into the page, so you'll definitely need to change how that's loaded. Otherwise the HTML code you're using looks like it should work.
I have created a simple - HelloWorld.html Webpage with HTML, JavaScript, CSS.
When I run it from Eclipse IDE, It works perfectly on browser.
What it does is like: the page has 5 buttons,
and hellow World is displayed from 5 different <div>'s
that remains hidden and appears as inline after button click.
When I navigate to the work-space and try to open the HelloWorld.html file in browser manually, nothing comes correctly.
All properties: positions and bgcolors etc declared in external css file has no effect on browser.
I know it sounds stupid, but I'm just hating myself for this.
Does anyone know why is it behaving in this way?
PS:
1. I have no Server-side scripting in the file.
2. HTML, JS, CSS are different file.
My best guess would be that you are trying to use the css file with a realtive path, which changes when you don't host it temporarily as eclipse IDE does.
First, open the developer toolbar (f12) & check the network tab to see if the css file is being loaded at all.
Try using an absolute path instead & see if it changes anything.
In my Exp. i have seen this kind of problems many times, the Inbuilt browser of eclipse some times does not support all features especially when you doing like designing purpose.
you can use MS-IE 6 or Above version for same.
or you can try some other browsers like:- Mozilla,Chrome etc.
because it has features for developers for scripting , div , css and many more . so u can check with them.
Thanks,

It's because of file manager from which you have opened.
You just need to see the link in browser.
If it has a "content//:" in start then the css or JavaScript file you have linked in the HTML will not work.
What you need to do is change your file manager or create link manually.
To create a link manually you should use "file///:"in start for example if your file is in download then you should use something like that....
file:///storage/emulated/0/Download/My%20Web/index.html
Or you can use ZArchiver file manager and go to your file and use open with option to open file in browser.
I have a page with a lots of javascript. However, the page once rendered remains static, there are no moving things or special effects, etc... It should be possible to render the same HTML without any javascript at all using only the plain HTML and CSS. This is exactly what I want - I would like to get a no javascript version of the particular page. Surely, I do not expect any dynamic behavior, so I am OK if buttons are dead, for example. I just want them rendered.
Now, I do not want an image. It needs to be an HTML with CSS, may be embedded with the HTML, which is fine too.
How can I do it?
EDIT
I am sorry, but I must have not been clear. My web site works with javascript and will not work without it. I do not want to check if it works without, I know it will not and I really do not care about it. This is not what I am asking. I am asking about a specific page, which I want to grab as pure HTML + CSS. The fact that its dynamic nature is lost is of no importance.
EDIT2
There is a suggestion to gram the HTML from the DOM inspector. This is what I did the first thing - in Chrome development utils copied as HTML the root html element and saved it to a file. Of course, this does not work, because it continues to reference the CSS files on the web. I guess I should have mentioned that I want it to work from the file system.
Next was to save the page as complete with all the environment using some kind of the Save menu (browser dependent). It saves the page and all the related files forming a closure, which can be open from the file system. But the html has to be manually cleaned up of all the javascript - tedious and error prone.
EDIT3
I seem to keep forgetting things. Images should be preserved, of course.
I have to do a similar task on a semi-regular basis. As yet I haven't found an automated method, but here's my workflow:
Open the page in Google Chrome (I imagine FireFox also has the relevant tools);
"Save Page As" (complete page), rename the html page to something nicer, delete any .js scripts which got downloaded, move everything into a single folder;
On the original page, open the Elements tab (DOM inspector), find and delete any tags which I know cause problems (Facebook "like" buttons for example) (I also try to delete script tags at this stage because it's easier) and copy as HTML (right-click the <html> tag. Paste this into (replace) the downloaded HTML file (remember to keep the DOCTYPE which doesn't get copied;
Search all HTML files for any remaining script sections and delete (also delete any noscript content), and search for on (that's with a space at the start but StackOverflow won't render it) to remove handlers (onload, onclick, etc);
Search for images (src=, url(), find common patterns in image filenames and use regular expressions to replace them globally. So for example src="/images/myimage.png" => |/images/||. This needs to be applied to all HTML and CSS files. Also make sure the CSS files have the correct path (href). While doing this I usually replace all href (links) with #;
Finally open the converted page in a browser (actually I tend to do this early on so that I can see if any change I make causes it to break), use the Console tab to check for 404 errors (images that didn't get downloaded or had a different name) and the Network tab to check if anything is still being loaded from the online version;
For any files which didn't get downloaded I go back to the original page and use the Resources tab to find them and download manually;
(Optional) Cull any content which isn't needed (tracker images/iframes, unused CSS, etc).
It's a big job. I'd love a tool which automated all that, but so far I haven't found one. The pages I download are quite badly made (shops) which have a lot of unusual code, so that's why there are so many steps. You might not need to follow every step.
I have downloaded a aspx webpage and saved it as html. I open it in IE and chrome and it takes time to load + some parts are missing. All the text is there but the onmouseover is not working properly and some css is not displaying correctly. Was the content not downloaded completely? i.e is it missing sme javascript, css or else?
I have done what you describe on many occasions for the purposes of putting together a prototype of new functionality in an existing application.
You will likely need to do a couple of things:
Ensure the paths to your JS and CSS resources are right (removing the unneccessary JS files, if any)
Also, you will likely need to update the paths in your CSS to any image resources in your page
I am building a website using PHP and JavaScript, and I feel that I have a good grasp on where to include my JavaScript, but a more specific situation has come up that has me confused. I currently have all of my JavaScript in one external file, which is being included on every PHP page.
Let's say that I have a paragraph with an id='myParagraph' and I need to highlight this paragraph in red with JavaScript on page load. This paragraph is only on ONE PHP page and my website has about 50 different pages. I immediately assumed that I should throw some code into my one external JavaScript file, something like:
$('#myParagraph').css('color', 'red')
and the paragraph would be highlighted when that page loads.
My question is: is this the best way to do it? To my understanding, every time I load a page it will be searched for an element with the id myParagraph, yet 98% of my pages won't even have that id. Is this wasteful? Should I instead include the following code:
function highlightParagraph()
{
$('#myParagraph').css('color', 'red')
}
in my one JavaScript file and then put some inline JavaScript in the PHP file with the id myParagraph to call the function highlightParagraph() when it's loaded? That way, only the one page with myParagraph will be searched and highlighted.
I feel like option 2 is the best, but I read all the time not to use inline JavaScript.
edit: I realize that for this example you would just use CSS. I'm just using it to get my question across
You should have a one "big" js file with the infrastructure functions and all the pages should have a reference to it.
Then each page should reference another js file with the functions related only.
The good things about using external js files are:
The files are cached after the first download => Faster surfing.
Separate of concerns, you keep the presentation tier away from the scripting tier.
Another important note:
The best way to change css is with css... not javascript.
I
If you change the element style on DOM ready, just add the element definition
#myParagraph{color: red;}
The problem with inline JavaScript is you might be starting with a few lines now, but in a few weeks or months, it will add up and be a lot of inline JavaScript.
That is bad, because inline JavaScript can't be cached by the browser like JavaScript files that you include with <script src="path/to/file.js" />.
That's bad because you add a lot of content that will be fetched every single page view by the user, adding load on your server bandwidth and slowing page load for the user.
If it's just a few selectors, don't worry; The time wasted on it won't cause any browser to sweat.
Though, if it becomes a lot of code for a different page/module of your site, you might want to split it into a different JavaScript file and include just that file when certain pages are loaded.
That way, the browser will cache that file and save that bandwidth for you and the user.
I wouldn't be too surprised if many people disagree with me (violently even) but I don't have a problem with putting a javascript tag with specific javascript for that page in the header if it will reduce the number of files or overall complexity of the project. Most of the core things that are done everywhere should of course be separated in another file but if it is a one page deal, then I would go for cleanliness.
The same goes for css, if it is specific to that page just put a css tag in the header with the specific changes that differ from the master css file. BTW as everyone is pointing out, this is a case where you want to just use CSS.
