i built a website (node&express&ejs) and when i go to different pages within this site i always have a short white screen before its loading.
how can i prevent it from happening? the loading time is fast, but i still want that in that 0.1 sec the background will be shown so it will look more smooth (its a dark-ish background so its very noticeable when it goes to white).
tried some googling and an option i saw is adding inline css background to the body, and showing all the rest only after document ready. but what is my alternative as im using node, so i cant use docuemtn?

I used Coverage to identify unused CSS and JavaScript Code on my landing page. This helped tremendously to reduce loading times. But now I experience the problem that when I view my page on a small device there seems to be missing css code (or javascript code not sure about that) for a drop down menu which should transform into a burger menu.
So my question is how does coverage calculate code which is not used. Does it do this just with the current browser view (which probably does not use all css code in case of responsive design?)
If this is true how can I find out whats really not used. Try various resolutions and run coverage several times?
Anyone experience the same problems?
The coverage panel is "live", as you use the page more CSS and JS will be used.
What I mean is that when you first load the page all of the CSS and JS required to render and make interactive that initial view will be highlighted as green and needed. If you then opened your menu that CSS would turn green as it was used. If you never open your menu with the coverage panel running it will not count the CSS as needed.
So because your menu CSS code was not needed when you ran the coverage panel and you removed the CSS for the menu you obviously will have issues.
You are kind of misusing the coverage panel, it is more intended to help you optimise your critical CSS or to find libraries that are completely unused.
If you want to use it to identify CSS and JS that is not used at all you would have to resize the screen to every break point (to account for different screen sizes and the different layouts you use for mobile, tablet etc.), open every menu item, tab to all areas of the site, fill in all the forms, both correctly and incorrectly etc. to ensure all states were covered and the relevant CSS and JS was used.
If you did manage to successfully do the above, that would show you the coverage for one page, but what about other pages? You would have to repeat the process there to ensure you haven't removed a needed style. As you can imagine this is not likely to be successful without mistakes!
Instead you should use the coverage panel to identify items that are required for "above the fold" content as this means you can inline any critical CSS and JS within your initial page HTML and get sub 1 second First Contentful Paint etc. (Yet again you need to resize the screen here to account for different breakpoints, but you do not need to open menus etc.)
Don't use it to try and identify things that aren't used unless you are absolutely certain they will not be needed (for example if there is a whole library included by mistake that does not get used, you can safely remove that.)
Can someone please tell me why I'm getting a green square on my Phaser game canvas as below?
Without seeing any code I can tell you that you'll see that when an image can't be loaded by the Phaser framework.
Open developer tools in your browser of choice and refresh after opening the Network tab. You should see a 404 for one of your images.
I believe if you look at the standard browser console you may also see messages about the name of the asset that it failed to load.
I had a slightly different case. Images were being loaded in the init function, which apparently doesn't work. I renamed that function to preload and suddenly the green squares are gone and the images show up.
My case was also a little different too; it appeared that all my image resources were loaded, but I think I was trying to create the sprites a little too quickly - in order words, I was trying to create and add sprites to my scene before the scene was properly loaded.
I'm going to try waiting until 'scene.scene.isActive(key);' returns a boolean of true.....maybe that's what will solve my issue. Failing that, I might just put in some sort of sleep/await promise of 1 second or something (not ideal, but might work)
ALSO NOTE: Part of the reason I was able to create my sprites too quickly was because I was doing so in my own custom function, not the typical create() function. Actually, the best solution is probably to create my sprites in the create() function and not a custom function...
Is there any way to show my website exactly the same way how it works on PC, tablets or notebook? I've got full HD laptop and i'm using Chrome - everything works great. On my tablet 10" I also have full HD resolution and Chrome and my website shows like this one on notebook. When I try to to show it on my full HD Lumia 1520 it's crap. I don't use Chrome here so I can understand that some element can be broken by interpreter but it's so approximate that every element go on the others. It looks like 640x480.
Is it some way to force approximate?
If the site developed is not responsive according to the screen size it will not display the content present on it in well manner, you must use bootstrap in your website to make it responsive for all kind of screen resolutions. It may has problem in the CSS. So check the css you used.
Try to use meta tag called view-port. There are different situations and you may set up your website appearance with media queries for responsive results or manage it for being non-responsive but comfortable.
If you need second result - don't use any responsive frameworks or prevent them of using responsive techniques.
There are to much different situations so I can help only if you'll show me the code you have.
I am trying to find the best method in order to create a horizontal website, full screen and if possible responsive, minimum width to be for tablets. The thing is that I need also the horizontal scrolling with the mousewheel, and I saw that fullPage.js doesn't support that or at least i couldn't manage to make it work on this plugin.
Anyway, I need an idea on building the template, with full screen sections displayed inline - I will be very grateful for any tip. Thanks.
Making horizontally responsive is bit tricky and requires a lot of effort.. There can be many many design approaches for making it responsive. It can't just be described with JSFiddle snippets..
However, I have something for you that will definitely get you started with "Horizontal Responsive Layout designing"..
This is must guide / tutorial for people who want to get started with Horizontal Responsive approach
http://tympanus.net/codrops/2012/04/02/responsive-horizontal-layout/
you could use one of the tools listed in the following links
http://www.cssdesignawards.com/articles/15-excellent-jquery-plugins-to-spice-up-your-sites/44/
http://jquery-plugins.net/scrollit-js-jquery-plugin-for-scrolling-pages
or you could also mix raw js/jquery with anchor links and add animations when clicked. in taht case you can scroll down using mouse wheel and also have fancy animations when a link is clicked
regarding responsiveness use css media queries
I know this type of question has been asked many times before but I haven't found an answer to my specific issue yet so I thought i would post.
It's really a bit of a quirk I guess rather than anything else but I have designed a responsive site that resizes nicely in a browser when you resize the window and works perfectly when you load it up in either portrait or landscape on a mobile. However when you load it in portrait and then turn the mobile into landscape some mobile browsers don't load up the correct styling for the new screen size - BUT IT DOESN'T HAPPEN LIKE THIS FOR ALL BROWSERS! So far I have tested it on an Android 4.0.4 version phone using the standard Android browser and it resizes correctly when switching orientations but then on the same phone using google chrome as the browser it applies different styling BUT if you refresh the page it then applies the correct styling.
So my question is how can I force the mobile browser to render the page correctly on orientation change without having to reload the page?
The site in question is www.the-baobab.co.uk and im using the viewport meta tag and setting it to width=device-width and an initial scale of 1 then calling media queries at certain max pixel widths to alter positioning and layout for various different screen sizes which can be seen in my stylesheet1.css here
