How can I edit the CSS directly on a tab which is displaying an HTML file? By clicking the "edit source" button, I can see the HTML, but not the CSS. Is there a way to see the CSS is a split panel view?
Great question. We're working on CSS/JS editing in the split panel view within Divshot and it should be available very soon. I'll update this post when it's released.
If you are trying to find the css file in your web browser then you can follow the below stapes-
In google chrome or mozilla firefox right click on the browser select inspect element -> inspector tab -> Rules -> edit the css value then you can see the changes css value is applied in your webpage.
Note:- It is applicable for tab, laptop, computer etc.

I am trying to create a scraper using vb6, my technique is to search the html page with get between 2 text function.
the function is tested and working correctly for all the sites, except a new site that I tried to use the same technique with it and failed.
The problem is the html is not showing the data, piece of the html as below:
<tr>
<td valign="top" nowrap="nowrap" class="label">Company Name:</td>
<td><span class="search-custom" id="synopsisDetailsOppNum"></span></td>
</tr>
the value should appear between the span tag above, but it's not appeared inside the HTML as above code.
The website is using javascript to manage the data.
I have tried also to use wait function, may the data appear with the HTML, but failed too.
Is there any solution to get the value, even with vb.net as I can update my code
that website is using JavaScript to add data to the webpage and such manipulation will not show up on the page source
The follwoing is quoted from JavaScript & jQuery: The Missing Manual by David Sawyer McFarland
One problem with using JavaScript to manipulate the DOM by adding,
changing, deleting, and rearranging HTML code is that it’s hard to
figure out what the HTML of a page looks like when JavaScript is
finished. For example, the View Source command available in every
browser only shows the web page file as it was downloaded from the web
server. In other words, you see the HTML before it was changed by
JavaScript, which can make it very hard to figure out if the
JavaScript you’re writing is really producing the HTML you’re after.
For example, if you could see what the HTML of your page looks like
after your JavaScript adds 10 error messages to a form page, or after
your JavaScript program creates an elaborate pop-up dialog box
complete with text and form fields, it would be a lot easier to see if
you’re ending up with the HTML you want. Fortunately, most major
browsers offer a set of developer tools that let you view the rendered
HTML—the HTML that the browser displays after JavaScript has done its
magic. Usually the tools appear as a pane at the bottom of the browser
window, below the web page. Different tabs let you access JavaScript
code, HTML, CSS, and other useful resources. The exact name of the tab
and method for turning on the tools panel varies from browser to
browser: • In Firefox, install the Firebug plug-in (discussed on page
477). Open a page with the JavaScript code you wish to see and open
Firebug (Tools→Firebug→Open Firebug). Click the HTML tab in the
Firebug panel, and you’ll see the complete DOM (including any HTML
generated by JavaScript). Alternatively, you can use the Web Developer
toolbar in Firefox to view
both the regular HTML source, and the generated HTML. • In IE 9, press
the F12 key to open the Developer Tools panel, then click the HTML tab
to see the page’s HTML. In the case of IE9, the HTML tab starts by
showing the downloaded HTML (the same as the View Source command). But
if you click the refresh icon (or press F5), the HTML tab shows the
rendered HTML complete with any JavaScript-created changes. • In
Chrome, select View→Developer→Developer Tools and click the Elements
tab in the panel at the bottom of the browser window. • In Safari,
make sure the Developer menu is on (choose Safari→Preferences, click
the Advanced button, and make sure the “Show Develop menu in menu bar”
is checked. Then open the page you’re interested in looking at, and
choose Develop→Show Web Inspector. Click the Elements tab in the panel
that appears at the bottom of the browser window. • In Opera, choose
Tools→Advanced→Opera Dragonfly. (Dragonfly is the name of Opera’s
built-in set of developer tools.) In the panel that appears at the
bottom of the browser window, click the Documents tab.
so the scraper won't download the page after the JavaScript finished it will get what it looks before any the JavaScript manipulation

I want to copy some html code from the web inspector but am only able to copy one line at a time. Is there any way to select a block of elements or all elements?
If you right click on any element in the Web Inspector, then click "Copy as HTML" on the resulting pop-up menu, you can then paste the html for that element (and all enclosed elements) into your editor. You can get the entire document by doing this with the <html> element.
On the console, try document.documentElement.outerHTML.
You could view the html response from the Network section of Chrome
Is there any way of getting the source code of an HTML browser-page that is showing when i click inspect element(in chrome of firefox) and put it in a notepad(automatically) or maybe accessing it automatically somehow.
I do not want the original sourcecode but the one that is generated after all the javascripts have already run.
I would like to use the code afterwards in another web page and parse it...
later edit: i can actually click the html in the inspect element and click copy html but i need for a nother site to automatically acces this information because i will try reloading the site at regular intervals and need to constantly get the new html
With Firebug's HTML tab, you can right click on the element, and click "Copy HTML".

how to get fully computed HTML (instead of source HTML)?
press ctrl+u then it will display source code of html page then go to file menu and save it as html file in your system. then you can open it in html or another editor like netbeans /dreamviewer/notepad. I suggest you to open it in netbeans or dreamviewer will be better then open it in notped.
thanks.
You can use the web developer plugin for Firefox or Chrome. It gives you the generated source of a page.
In Opera , Right Click -> click on Inspect Element -> right click on <html> tag -> click on Edit Markup, from there you can copy the entire HTML code.
Edit -> In Oprea, right click on the page -> click on Source -> a new tab opens , in the menu bar of newly opened tab you have option 'Save' , from that option you can save the html code as .html , .txt.
Hope this helps you.

How to identify unused CSS definitions from multiple CSS files in a project
(3 answers)
Closed 1 year ago.
I have a lot of CSS files on the page. But a lot of these files are not used by styles. Is it possible to determine which files are used by page and which not.
Use http://getfirebug.com/ to debug the page.
When looking at the css it will reference which stylesheet is used.
For example:
You can see from the screenshot that when using Firebug it shows in the blue text that the page is using the style.css stylesheet.
Work down the tree in Firebug and simply hover over your elements and see which stylesheets are used.
You can debug with firebug ( http://getfirebug.com/ ). It will show what is used for what and allows you to find out.
You can do one thing :
open the website in Firefox
Use firebug to point some control on which you want to see the applied classes.
In the html source code in firebug , you can find the applied css classes on a particular control.
Find those classes in your CSS files.
Repeat this process for all the controls of the webpage.
Now you can remove those CSS files that are not used on that web page.
Thanks.
New in Chrome 59 is the coverage tool that shows you CSS and JS code coverage. It'll show you what percentage of CSS files are used on a page. When you click on that file, it'll show you which styles are used and which ones aren't. More info here: https://developers.google.com/web/updates/2017/04/devtools-release-notes#coverage
Use Web Developer Addon with firefox.
http://chrispederick.com/work/web-developer/
After installing this addon goto firefox tool->web developer -> css-> view css.
There are many ways to find which CSS are being used by page.
here are some of them:
1) if you are using firefox then firebug is useful to use. http://getfirebug.com/
just right click on page and use Inspect Element option
2) if you use IE,then Developer tools is available in IE
3) If you use google chrome,then u can directly use Inspect Element option by right clicking on page.
The way to find or access to CSS files are used for current page, could vary base on the Browser and/or Operating system you are using.
Here I am going to share with you Opening the “Console” panel (Developer Tool) of Chrome, Firefox, Internet Explorer, Safari, Opera in both Windows and Mac OS.
When you open the Console of the current browser, click on the element you want to inspect and on the right hand side you will have a tab name Styles as shows below:
As you can see the image has the name of the CSS file (in this example named "desktop_ltr.css")
I have PHP generated HTML.
Firebug shows me this source:
<div class="module-header"><div class="module-header2"><div class="module-header3"><h3 class="module-title" style="visibility: visible;"><span>Մարդկային</span> ռեսուրսներ</h3></div></div></div>
Mozilla Source shows me another HTML for that part.
<div class="module-header"><div class="module-header2"><div class="module-header3"><h3 class="module-title">Մարդկային ռեսուրսներ</h3></div></div></div>
Actually this part should work as link. But doesn't...
Firebug is showing you the actual page content at that exact moment, whereas "Show Source" is showing only the static HTML that got downloaded from the server.
If JavaScript is making any changes to the page, the two will be different. In this case, it looks like JavaScript is removing your link and hiding the h3 element.
I see a style="visibility: visible; in Firebug's source. Are you sure you are not messing with the HTML via Javascript and some .show() .hide()?
Firefox's Source is the way to go for static HTML -> There is no rendering difference from what you see in your browser window and the source you see with Right Mouse BUtton > View Source, but (there always is a but) if you change the source dynamically - e.g. via JS when hovering over one link it hides some other part of the website - the Firefox "View Source" will be wrong and not reflecting these dynamic changes - these you will only be able to see with Firebug.
Maybe you can try a different browser and see if it is working there as a link?
Javascript might interact with your page and could hide the link because of some pre-condition. Maybe you want to turn off Javascript and see if your link is working then?
