How do I use the HTML Agility Pack?
My XHTML document is not completely valid. That's why I wanted to use it. How do I use it in my project? My project is in C#.

You can apply this CSS to the inner <div>:
#inner {
width: 50%;
margin: 0 auto;
}
Of course, you don't have to set the width to 50%. Any width less than the containing <div> will work. The margin: 0 auto is what does the actual centering.
If you are targeting Internet Explorer 8 (and later), it might be better to have this instead:
#inner {
display: table;
margin: 0 auto;
}
It will make the inner element center horizontally and it works without setting a specific width.
Working example here:
#inner {
display: table;
margin: 0 auto;
border: 1px solid black;
}
#outer {
border: 1px solid red;
width:100%
}<div id="outer">
<div id="inner">Foo foo</div>
</div>EDIT
With flexbox it is very easy to style the div horizontally and vertically centered.
#inner {
border: 1px solid black;
}
#outer {
border: 1px solid red;
width:100%;
display: flex;
justify-content: center;
}<div id="outer">
<div id="inner">Foo foo</div>
</div>To align the div vertically centered, use the property align-items: center.
I use javascript:void(0).
Three reasons. Encouraging the use of # amongst a team of developers inevitably leads to some using the return value of the function called like this:
function doSomething() {
//Some code
return false;
}
But then they forget to use return doSomething() in the onclick and just use doSomething().
A second reason for avoiding # is that the final return false; will not execute if the called function throws an error. Hence the developers have to also remember to handle any error appropriately in the called function.
A third reason is that there are cases where the onclick event property is assigned dynamically. I prefer to be able to call a function or assign it dynamically without having to code the function specifically for one method of attachment or another. Hence my onclick (or on anything) in HTML markup look like this:
onclick="someFunc.call(this)"
OR
onclick="someFunc.apply(this, arguments)"
Using javascript:void(0) avoids all of the above headaches, and I haven't found any examples of a downside.
So if you're a lone developer then you can clearly make your own choice, but if you work as a team you have to either state:
Use href="#", make sure onclick always contains return false; at the end, that any called function does not throw an error and if you attach a function dynamically to the onclick property make sure that as well as not throwing an error it returns false.
OR
Use href="javascript:void(0)"
The second is clearly much easier to communicate.

First, install the HTMLAgilityPack nuget package into your project.
Then, as an example:
(NB: This code is an example only and not necessarily the best/only approach. Do not use it blindly in your own application.)
The
HtmlDocument.Load()method also accepts a stream which is very useful in integrating with other stream oriented classes in the .NET framework. WhileHtmlEntity.DeEntitize()is another useful method for processing html entities correctly. (thanks Matthew)HtmlDocumentandHtmlNodeare the classes you'll use most. Similar to an XML parser, it provides the selectSingleNode and selectNodes methods that accept XPath expressions.Pay attention to the
HtmlDocument.Option??????boolean properties. These control how theLoadandLoadXMLmethods will process your HTML/XHTML.There is also a compiled help file called HtmlAgilityPack.chm that has a complete reference for each of the objects. This is normally in the base folder of the solution.
