My dad's company asked me to change the menu bar of their website. Basically, I just opened the page source (Ctrl + U) of the website, copied and pasted all the HTML and CSS to notepad++ and changed some of the HTML code (just to try it out and test it to see if it works) and saved it as an HTML file. But how do I permanently save the changes to the actual website so that everyone can see it? Sorry if this sounds like a noob question. My HTML skills are at beginner level.

It isn't possible to edit arbitrary websites. If it was, every major website would be covered in spam and pornography.
You have to have access to the server. The specifics depend on how the site is set up. There might be a content management system to edit it through, there might be a SFTP server you drop static files in, there might be any number of other approaches.

This desktop save isn't gonna work. You need access to the original files of the hosted website!
Like, if its a wordpress blog, you need to get access to its admin-panel
or if its a tailored website, you need to get its FTP access, then you can download that page, make changes and re-upload it on the same location - that's it!
Both require some credentials - for example if your website url is example.com, then it may be something like:
for wordpress: example.com/wp-admin/login.php
for site: ftp.example.com

The code you see on the browser are just built out of some raw data that are provided (sent) by the server for your browser. The browser engine makes its own version of source code from that data to be able to display the page to the end user. This code is most probably very different from the actual source code that the developers have written.
Also, You don't have the permission to change the website from your browser. You need to access to the server and make your changes from there.
Just like you can't make changes to a tv programme by changing the audio/video settings of your own television and you need to access to the devices in the studio to make real changes to it.

Webpage practice [duplicate]

This question already has answers here:
Is there an HTML/CSS/JS editor that immediately shows changes? [closed]

Closed 6 years ago.
I have been learning HTML + CSS via online courses like codeacademy and W3schools. I have a very simple grasp as to creating webpages and I want to play in a "sandbox" by creating pages and just messing with stuff.
I'm looking for somewhere I can type in my HTML and CSS and have it display on a webpage just like any other page I look at. I haven't been able to find anything quiet like that, other than the courses themselves. Is there even such a thing?
You could try JSFiddle
It accepts JS, HTML, CSS and renders it realtime...
You can download a coding software such as Brackets. Save your html file as index.html and your css as styles.css (per example) in the same folder.
Simply click on them in your computer's documents and it should work, opening in your default browser. You don't need an "online" tool for html/css.
Also check out this blog post for alternatives
I would highly recommend http://codepen.io. I find it the most user friendly of the bunch
I think JsFiddle would work for what you want. It also allows you to incorporate javascript as you begin to branch out. Plunker is also something I would recommend as it has a "live preview" where your page will automatically display as changes are made.
Get a free website from a site like 000webhost. Then, you can upload and edit code in real time on the server and view it on eg. http://example.freehost.com and you can view it real time. Also you could use software like notepad++ and edit your code before uploading it. Make sure your homepage is index.html

downloading parts of a html page on an event

I am developing an universal windows app. I need to download a webpage and extract images from it.
I got the html code and extracted the links to images and downloaded them. The thing is, the site has infinite scrolling (like facebook). When I scroll down to the bottom it loads more images. I am not able to incorporate this into my app. I am a beginner and have very little knowledge of web development or windows app development. This is my first app. I am stuck and have no idea how to proceed. I don't want to use webview as it displays ads from the site and other unnecessary contents. I only want the links to those images. Please help me go past this situation. I need a way to download the new html content that the site loads when user gets to the bottom or some other way to get the image links.
Thanks in advance.
You may or may not be a me to implement this specifically because of the reason you stated. You need to determine how the site loads this information. First I would download Fiddler and in turn enable https connect logging so you can see your encrypted traffic going through Fiddler. Btw the Web View has events you can hook to see loading URLs, etc and it can also be hidden.
So again you need to first understand how the site you want to do this on works and emulate that, assuming they don't have an api already to give you this information as mentioned I'm the comments.
When you do that, come back with code examples and you'll get better help.

Improve this question
So I recently finished the HTML and CSS course at Codecademy, and I want to practice coding with html and css. My problem though, is that I don't know where to start. I've been searching around to try and find the information I need, but I can't find anything. I kind of feel like it's so obvious noone's ever needed to ask, but I don't know, so here I am, asking.
While searching for the answer to this question, I could only find sites that teach how to use html and css, like Codecademy, and sites that let you test html code like w3schools.com, but no sites that let you practice html and CSS.
Here's my question:
Are HTML and CSS created as .html and .css files on my computer?
You should ask new question for each of the questions you posted.
Where do I code html?
You can use any text editor. Try Sublime Text - download the app for your operating system and install.
Create a new file, saving it with the file exetension .html. Be sure you saved the file in an easy to find location - like you would with any word processing document or spreadsheet.
Open a browser (Safari, Chrome, Firefox).
Click and drag your new HTML file into the tab window.
Make some changes in your HTML file.
Refresh your browser tab.
You're now on your way to learning more about coding HTML in your local environment.
You can create HTML, CSS and JS files on your hard drive and simply open up the HTML file by double-clicking it (or opening it directly through the browser's file menu).
Typically these files are stored on an HTTP server that provides content when asked... but for your purposes to practice HTML and CSS, you can simply save the files on your hard-drive and open them from there.
Yes, they are (but CSS can be stored on a server as well, see 2.). You can then open the HTML file you're editing in any browser and see the output.
You can include CSS in your HTML file by using:
<link rel="stylesheet" type="text/css" href="path-to-your.css">
The path to CSS file can also lead to an online server, if the CSS file is stored there:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
The simplest way I can think to answer is:
Are CSS and HTML coded in a file on one's computer?
Yes
If so, how is the CSS connected to the HTML, and how are these connected to a website?
In the HTML file you specify which CSS files will be used in your page (I'm assuming you know what CSS files are for). The web browsers like Internet Explorer, Firefox or Chrome, read the HTML code and produce the sites you see anywhere.
If you are only practicing basic HTML:
Open notepad (Windows+R, type "notepad", enter)
Write some code like the found here: http://www.w3schools.com/html/html_basic.asp
Save your file with .html extension
Open it in your web browser by just double clicking the file
EDIT. Check this other example to see how to reference the CSS files http://www.w3schools.com/html/html_css.asp.
You only need to put your HTML file and CSS file in a folder in your computer, you don't need go to any site to practice this because HTML and CSS code is interpreted directly by your web browser.
Are CSS and HTML coded in a file on one's computer?
yes and no.
Basically CSS can be anywhere; your computer, your server, someone else's server, etc.
Your Chrome blocks some local sources for security reasons, but Firefox handles them pretty well. If you have a static website (that does not involve with any database), you can just create a directory and make html, css, and javascript files and open with Firefox to test.
Otherwise, get hosting services like godaddy, or get a server like Amazon Web Services and put them in there.
If so, how is the CSS connected to the HTML, and how are these connected to a website?
Typically, this is how people do.
<html>
<head>
<link href="css/style.css" rel="stylesheet">
</head>
<body>
<!-- your body... -->
</body>
</html>
If not, where are HTML and CSS coded for use on the web?
This was answered above.
CSS and HTML are not things that need to be installed on your computer, you just need to create a file with the .html extension, put some code in it and open it with a browser. The browser interprets it automatically, the same goes for CSS. To create HTML pages for practice, all you need to install is an IDE to edit your code.
Ok - everyone has to start somewhere and I'm going to assume you are a novice so if any of this information is too basic, please excuse it.
There are tiers to consider here....First let's break down what the languages do - I'm going to talk about additional languages because I see people already talking about servers and scripting to so I'm going to try and tie this all together for you. I started self taught and learned a lot of hard lessons so hopefully this add's a little bit of an advantage to the learning curve.
SERVER Think of a server as a computer. It run's slightly different software but the principles are the same. It's only job is to store code, interpret it and present it when called. A very popular server software that you'll find is apache so let's focus on this for now. Windows is not a server and can't be used as a server. However, it's possible to edit a server with windows and it's possible to run server software on top of windows just like any other application. You'll hear references to WAMP, LAMP, XAMPP and a bunch of other acronyms but for now you just need to know why they exist and what they do. A server is not required to write and produce html and css documents
HTML The primary purpose of HTML is to tell a web browser what it's looking at. You'll see a lot of HTML4 vs HTML5 and a ton of other arguments that won't make a lot of sense up front. The important thing to remember about HTML is that it is the framework for everything website related. A lot of people will argue that other languages are more important for one reason or another but without html, none of the other languages matter at all. Whatever you know about this is fine for now. Start small and work your way up.
CSS Is amazing. CSS3 is the current standard but there are still some things that are not cross browser compatible. That's a story for another day but the basics are the same everywhere. You define your classes, id's and elements then tell them how they're going to look. The more you get in to CSS the more you'll realize how amazing it really is. It's useful on a lot of levels and plays a big part in some scripting languages. The biggest thing to remember about CSS is that you should write as little as possible. The more rules you write, the more chance there is for overlapping and something you wrote 3 files ago on line 463 is going to dominate a new rule you just wrote. Try and write as much as possible in classes too so you can really make your code globally usable.
PHP/ASP These are just two of the more popular languages that are considered back end languages. When you're thinking of a website, break it down like this. Front end = Browser, Back end = server. Anything that PHP does is on the browser side. As an end user of a website, you'll rarely see it but it's a major component. This is relevant because as you grow, you'll wonder about trying your hand at a back end scripting language. That's great but that's when you're going to start getting in to servers and such so I'm sure you'll hear a lot about the benefits of it but for now, just stay focused on the basics until you're comfortable.
Javascript/jQuery Again, this is just two popular examples of the many scripting languages that are available on the client side(the browser). These languages can generally be viewed(and edited) by the end user. They are extremely useful for changing pages content without reloading the page and they can talk to the server languages as well. Again, get more comfortable first with your basics before branching out here but with the references you're bound to receive to these languages as you learn, it's helpful to know what they do and why.
Editor To edit html you can absolutely use any text editor. Word, notepad, notepad++, sublime-text, wordpad...literally anything that saves in a standard text format. As long as the extension is html, css, etc. The editors geared towards programming offer a lot of features and benefits as compared to the basic editors available in your windows/mac setup. Try your hand at a few different ones and see what suits your taste. You can write one file of html, download the programs and right click to open with each program to see the differences. Personally I recommend Notepad++ but to each his own.
Why is my answer so long? I know this is a majorly overkill answer to your question however I also know how hard it was for me to get started in this field without some very basic knowledge. This should be enough to get you off and running and hopefully help out when you encounter some unfamiliar territory. In the future, if you find yourself looking to get in to the server/scripting world, let me know and I'll pass along a write up I did on setting up xampp for windows.
Good luck!!
You need a text editor to practice your code I recommend downloading Sublime
Its free, in sublime under view you can change syntax which is the language you are programming in you can set it to html or css or any other language you desire.
The structure for "connecting" html and css is usually a simple folder like structure.
Create a folder called Website
In that folder you would have your html file(s) you can call it index.html
Also in that folder you would have sub folder(s) for your CSS and JS but since you are just working with CSS now create a folder named css. This is where you will save your css file that could be called something like style.css
Here is a more through guide on folder and directory structure.
Keep going with Codecademy and build your own projects in the browser.
I'd recommend taking a look at a good example. HTML5 Boilerplate is a good starting point and has some good practices for a project (in my opinoin). This may be a good reference for you to get a feeling of how the javascript and css files can be arranged and linked to. The website is static so you can open the index.html file with a browser to preview it. You can also make changes to the css and javascript files to see how this changes the index.html page.
https://html5boilerplate.com/
You're asking a very broad set of questions but hopefully there's quite a few good answers in here to point you in the right direction. Good luck!
It is technically possible to have both HTML and CSS in one file using the style tags:
<html>
<head>
<title>Title</title>
<style>
h1 {
color: blue;
}
</style>
</head>
<body>
<h1>Test Text</h1>
</body>
</html>
However it is considered proper practice to use Cascading Style Sheets, which is probably what Code Academy used.
Checkout setting up a WAMP, LAMP, MAMP server depending on your platform (W) Windows, (M) Mac, (L) Linux.
http://www.wampserver.com/en/
https://www.linux.com/learn/tutorials/288158-easy-lamp-server-installation
https://www.mamp.info/en/
Then in your respective directory (html_public, Sites, wherever) you will have a local server environment where you can develop locally.
I use the Sites/ setup on a mac
css and javascript are usually linked in the head section of an html document.
You will need a editor - I recommend looking at Sublime Text or Atom.io
If you just want to play around for a while before attempting your own projects, you can build on sandboxes like http://codepen.io
Are CSS and HTML coded in a file on one's computer?
A: depends either you can create both css and html in one file or in different files. If you using lots of css code then everyone will suggest you to write them in different files and you can code them in someone's computer or on server.
If so, how is the CSS connected to the HTML, and how are these connected to a website?
A: you said that you have done html and course and you don't know who to add a css file to a html file. (Use Google sometimes) use this link you Wil get you answer. After coding you can test them using your web development tool if you are developing in a tool. Else use your web browser to test.
I suggest you to visit websites as much as you can an use chrome tool to see how that website is done (you can only find front end parts.)

Possible to build an editable site in just HTML/CSS?

A local nonprofit needs a new website. It's a very basic website that simply presents information, nothing past basic HTML/CSS is needed to make the actual site.
The marketing manager would like to be able to edit text sections (upcoming events, jobs) regularly. How would I go about creating the site in HTML/CSS and then allowing them to edit just the text in those sections in an easy way? is that even possible, or would this require more advanced knowledge of actual programming/database languages?
Thanks
No, you can't edit the site with just HTML and CSS. Even if you have JavaScript, you'll need server side code (ASP.NET, PHP, Ruby on Rails, Node.js etc) to store the changed text, since HTML, CSS, and JS run on the client (excluding server side JavaScript based frameworks).
The easy solution is to just use simple HTML and tell him to directly edit the HTML. If he's just a little bit technical, an hour or two of explanation of how HTML works might be enough to get you going.
A CMS solution that is prebuilt and has simple menus for editing things might work nicely. There's plenty of various options to suit your needs.
Otherwise, you can either build a custom site. A custom site that reads text from simple text files might be all it takes (Markdown might be preferable to plain text.) Of course, you can scale it up if you want until you've basically built your own CMS.
You can't do that.
HTML pages are stored on a server (which is just a computer accessible by other computers via an internet connection), when you type in an address in your browser's address bar it sends a request to a server to fetch the corresponding HTML page. Then this page is displayed in your browser.
Now, say you managed to change a text in your browser somehow using HTML/CSS, but you still need to find a way to send these changes back to the server so that these updated pages are accessible by other remote browsers, and the only way of doing this is to use server side languages. They are not really that difficult, you can quickly learn that.
You might like to take a look at this sourceforge project.
This is a file-based system that uses conventional HTML for the webpages, but allows online editing with CKEditor. Requirements are Apache 2 and php 5.3 or later.

Unfortunately the short answer is that it cannot not be done in a good way, if the content should be available at your website at the same time.
There are solutions where you obfuscate the path to the file when it is sent to the browser, and then use a JavaScript to "decrypt" the path at the client. But those solutions are in no way bullet proof, as the decryption technique would have to be sent to the client as well.
This one is not easy to do, especially if you show them on your page already. As you do so they'll get downloaded on the browser an there's no way, at least i'm aware of you could do this with ease!
All you can do is to make it harder... but it still always be possibile! Even if you could stop them from downloading the file, you can't stop them from hooking a VCR to their video card and re-recording it. Even if you use some protected-path technology to stop that, you can't stop them from pointing a camcorder at the screen.
Same applies to the ppt presentations... as they can view them... users could take screenshots or do whatever to create their own copy!
