Classes vs ID

Classes they represent the group of entities(elements)

multiple elements can have same class barcode -> item name and price Nike Air -> all the Nike air will have same bar code

id they represent the a unique entity

one element can only have one ID serial number or unique code

*** Iphone8 imei number xxxxx

Let's talk about forms

used for getting the user data? yes

elements here

action is basically telling the form where to put data for processing -> backend

method = how you want to send the data

Let's talk about CSS cascading style sheets

Primary function is to make things look beautiful(people like beauty) Responsiveness

style is done by property and value

color: blue background-color: #fff -> white

property: value

How can you style your elements

style attribute inside the element tag

Another Iphone

This is my iphone

This is my iphone 9

click iphone9

while working with style tag

selector { properties: value; properties2: value2; }

why cascading cause it follows the order like this inline is applied at last and hence is always at top

best practice to do that is using a separate sheet for this has an extension of .css

and write all of your styles inside that sheet

classes are for groups and you can access your classes with

.phoneName{ font-size: medium; font-family: Arial, Helvetica, sans-serif; background-color: lightcyan; color: black; }

id are for elements and you can access your elements with

#hockeyCheckbox{ color: red; font-size: large;

}

id's overrule the classes
