In last tutorial we started the magic dom manipulation. Today we are going to learn about the dom selector so that we can select a dom part and change it as we want. Let’s start

I made a new html for us to edit. Have a look, code available in github

Alt Text

Now go to console and type document.get it will bring the autocomplete other options

Alt Text

So there is lot of different selector write ? We can use them to select something and edit that. We’re going to start from the tag select.

Now by just writing document.getElementsByTagName("h1") we can grab the h1. see

Alt Text

We got and HTMLCollection and in 0 we can see see the classname also. So how can get the value ?

Just using document.getElementsByTagName("h1")[0]

Alt Text

To avoid writing this big thing we can just write document.querySelector("h1") which is going to give the same thing for use

Alt Text

So can you select the elements you have in your html ?
