change font size for getElementsByClassName

Question

I scrap a paragraph in a page using getElementsByClassName. However, I unable to change the font Size and color of the output.

Below is my code to scrap.

var keyPeople1 = tmp.body.getElementsByClassName("cr_profile_people module")[0].children;
for (var i = 0; i < keyPeople1.length; i++) {
  keyPeople1[i].style.fontSize = "2em";
}
$scope.keyPeople = "<div class='cr_profile_people module'><div class='mod_headerBox'>"+keyPeople1[0].innerHTML+"</div><div class='cr_data cr_board'>"+keyPeople1[1].innerHTML+"</div></div>";

The for loop was suppose to change the font size but it just does not work.

html snippet

<div style="margin: 10px;" ng-bind-html="keyPeople"></div>

add fontsize in style <div style="margin: 10px;font-size:60%;"ng-bind-html="keyPeople"></div> has no effect on the font size.

Please guide the correct way to change the font size and its color.

UPDATED: With the current answers by @Manzurul and @Varun Sukheja.

1. The font size and color inside red box I draw ,both do not take effect

2. font size of table below the red box do not take effect, only color changed.

Thus, I am curious why the font size inside the red box unable to changed? More important how to changed it.

The picture is using

.controller("companyOwnershipCtrl",function($scope,$http,$ionicLoading,$state,$cashDataFactory){

$scope.companyDescriptionStyle = {"color": "blue", "font-size": "40px"}; 

in angularjs and <div style="margin: 10px;font-size:20px;" ng-bind-html="companyDescription" ng-style="companyDescriptionStyle"></div> in html, but you can notice the font size is same as the above.

Answer 1

Have a look I have used your all the ionic html code and also kept the h3 tags. And the ng-style is working fine.

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope, $http) {

  /*$http.get("http://manzurul.atwebpages.com")
  .success(function(response){ 
    console.log('workingsdfsdf');
    
  }).error(function(error){
 
    if(!error) {
        $scope.name = "No data found"
        $scope.companyDescriptionStyle = {"color": "red","font-size":"40px"}
    }
  });*/
  $scope.companyDescriptionStyle = {
    "color": "blue",
    "font-size": "40px"
  };
  $scope.name = 'World';
  //Company Info
  var companyInfo1 = null;
  var companyInfo2 = null;

  $scope.companyInfo = null;
  $scope.companyInfo += "";

  //Description
  var description1 = "";
  $scope.companyDescription = "<p></p>";


  //Key People
  var keyPeople1 = "";
  $scope.keyPeople = "";

  //Average Growth Rates
  var growth = "";
  var growth1 = "";
  $scope.averageGrowthRates = "";
  $scope.averageGrowthRates += "";

  //ownership
  var ownership = "";
  $scope.averageGrowthRates += "";
});
