LaTeX italics

Whether you would like to single words, sentences , paragraphs, or the entire text in italics , in LATEX it is possible. To write italics within LATEX, there is the command \textit. This allows individual words to represent a sentence and a paragraph in italics.
input:
In this sentence, is the last word \textit{italics}.
output:
In this sentence, is the last word italics.
input:
\textit{This sentence is in italics.}
output:
This sentence is in italics. input:
\textit{This sentence should be too long as he complete within a
Standard line are placed so that what is shown in italics with
Passes sentence when it comes within this set to a newline.}

output:
This sentence should be too long as he complete within a Standard line are placed so that what is shown in italics with Passes sentence when it comes within this set to a newline.
The \textit command cannot expand to an environment.
input:
\begin{textit}
From here, the whole text is in italics, right?
\end{textit}
output:
From here, the whole text is in italics , right? Here only the first letter is in italics.
To create an italic environment itshape is used.
input:
\begin{itshape}
This set is also very italic only this time as an environment.
\end{itshape}
output:
This set is also very italic only this time as an environment.
In principle, even single words, and sentences can make etc. with itshape italic represent as the following examples show . input:
{\itshape italic } \\
{\itshape Italic sentence with itshape instead of textit.}\\
output:
italic
Italic sentence with itshape instead of textit.
The disadvantage of itshape here is that the command cannot be interleaved with other commands to markup . For example, italics and bold
{\itshape {\textbf This sentence is italicized but not bold. }} \\
This sentence is italicized but not bold.
To achieve this, itshape be used as a switch, the desired area of the text is marked, and finally switches to the normal typeface.
\itshape
From here, the whole text is in italics, to the end of the document,
or there is a \textbf{normal font} as a switch \normalfont
from then the text is back to normal. \\
From here, the whole text is in italics , to the end of the document, or there is a normal font as a switch from then the text is back to normal.
The desired can be but also by combining textbf and textit realize:
input output
\textbf{\emph{bold italic}} bold italic
\emph{\textbf{bold italic}} bold italic
\textbf{\textit{bold italic}} bold italic
\textit{\textbf{bold italic}} bold italic
As you can see from the example, the commands emph and textit perform the same result. An important difference between the two is that if emph is used within an emph enviroment that removes the highlighting again textit does not. input:
\emph{Text that is emphasized, but now \emph{not} again now.}\\
\textit{Text that is italic, but now \textit{still}.}
output:
Text that is emphasized, but now not again now.
Text that is italic, but now still.

Coarse emph said for single words, textit or itshape for entire documents. There may be other views.

2LATEX bold

On the subject of LATEX bold immediately occur to me that people who use the section or subsection command to , for example to write Task 1:. As cursive writing also bold letters are available in LATEX. The counterpart of \textit{\ldots} is \textbf{\ldots} and \itshape is \bfseries.
input:
In this sentence the final word is \textbf{bold}.
output:
In this sentence the final word is bold.
input:
\textbf{This sentence is bold.}
output:
This sentence is bold.
input:
\textbf{This sentence should be too long as it could be complete within a
standard line, so that it could show what happens if a bold
sentence comes to a new line.}
output:
This sentence should be too long as it could be complete within a standard line, so that it could show what happens if a bold sentence comes to a new line.
input:
\begin{bfseries}
This set is also very bold but this time as an environment.
\end{bfseries}
output:
This set is also very bold but this time as an environment.
\bfseries
From here, the whole text is bold, until the end of the document,
or there is a \textit{ normalfont } as a switch \normalfont
from there the text is back to normal. \\
From here, the whole text is bold, until the end of the document, or there is a normalfont as a switch from there the text is back to normal.
