Regex Password Validation

I needed to find a regex pattern for validating a password for an Angular app.
The requirement were to have at least 1 lowercase character, 1 uppercase character, 1 number, and no repeating character more than 2. For the ng-pattern, I came up with is below


Breaking It Down

(?!.*([A-Za-z0-9])\1{2}) Make sure that no characters repeat more than twice

(?=.*[a-z]) requires at least one lowercase

(?=.*[A-Z]) requires at least one uppercase

(?=.*\d) requires at least one digit

In jQuery, getting a numeric property returns a string.
What if we want a css property value as an integer or float?



Expand Div with Floats

How do you expand a div to contain floats?
Elements like div’s grow to fit its contents, but when you use the float property on its children, the div will not expand.
The div will show a height of 0.

Solution to Contain a Float

Set the parent to overflow:auto.

<div style="overflow: auto;">
    <div style="float: left;">Div 1</div>
    <div style="float: left;">Div 2</div>
