PFX File from CER/PEM(Public) and Key File(Private)

https://support.globalsign.com/ssl/ssl-certificates-installation/install-pfxpkcs12-internet-information-services-iis-7

openssl pkcs12 -export -in linux_cert.pem -inkey privateky.key -out output.pfx

PFX file has a Password - This password is for protecting contents of this container to be visible to others except those who know password

Private Key - While Making a Private Key -We too give a Passphrase for encryption

PrivateKey Passphrase and PFX Container Passphrase are different.

• The username and the password are combined with a colon (aladdin:opensesame).
• The resulting string is base64 encoded (YWxhZGRpbjpvcGVuc2VzYW1l).

Float, Flexbox, Grid, Bootstrap, CSS, Less, SASS

 Float  Flexbox Grid Bootstrap

Tables as layout ??? ---- Very Bad - Very Primitive

Next Option was ::Float::
Images /text - Float was originally designed for text to be wrapped around image

img  {
  float: left_Which side it goes
  clear : which_Side_They are not allowed
}

//h1 in general
h1 {
}

//h1 Nested inside div
div h1{
}

.greet , .welcome .{
font: ;
    color : black;
margin-
}

float when applied to div inside a section becomes responsive kind of 
and we get a layout, You also need holding Container 1st which will contain all div's.

<section>
<div> clear:both  ---- Top
<div> float: left   ---- Left
<div> float: none ---- Centre
<div> float:right  ---- Right
<div> clear:both  ---- Footer
<section>

Float Clear --> Flawed Logic  --> Hackish
