How to write html codes INSIDE a blog post of in a website

Sometimes you may want to write html or css codes inside a blog post just to show the codes or to share with friends . It’s a nuisance in blogger, when you write HTML/JavaScript in the post it will not show up as text. Actually blogger by default tries to interpret the written code. To overcome this, you will have to alter your HTML/JavaScript as follows:Replace all the < characters with <
And all the > characters with >
(Exactly the same including the semicolons).

For example if you want to write the below given code in your post
<![CDATA[ 


Then it will be written as <b:skin><[[CDATA[ in the Compose box.
