When I hover over .section-2 in inspector it appears like it’s off the screen but the page won’t let me scroll down. When I turn off position absolute on the header I can see the first two letters of it but again it goes off-screen and doesn’t allow me to scroll.

        * {
        margin: 0;

I am just starting to use the GSAP 3 API. I am simply trying to have 3 cards animate from 0 to 1, when the user begins to scroll and the cards begin to enter or are completely in the viewport. But what’s happening is though the cards are out of the viewport frame, the animation begins automatically. It’s like the scrollTrigger object has been completely ignored.

What adjustments do I need to make here?
I’d appreciate it.

main.js

import { gsap } from "gsap";
import {ScrollTrigger} from "gsap/ScrollTrigger";
gsap.registerPlugin(ScrollTrigger);

function init(){

    gsap.from("article", {
        scrollTrigger:{
            trigger:".cards",
        },
        stagger: {amount: 0.5},
        scale:0, duration:3
    })   
}

window.addEventListener('load', function(){
    init();
});

the html

<section class="cards">

How can i write correctly this code, in such a way that it is a valid if syntax, and if it is not respected, should I have someone else with it?

Basically I want to search for a text in a popup window. If it does not exist, enter the code in else statement.

cy.get(".ibxudA").find('.WildnessText-kRKTej').should('have.text',"Wildness")

Hi I am new to Angular and I want to bind my dropdown options with value as

I have a CSV file of readings from a sensor that I would like to graph with chart.js on a flask server, however I am getting 404 errors when trying to access the CSV file, since I am getting 404 errors I am assuming that I need to actually path the CSV file in flask, but I cant figure out how to do this, I’m coming across a lot of irrelevant information about using flask to make and fill a database but I need to pass the database to an html page to parse for graphing.

Could someone please help me learn how to do this?

Code that I’m testing and playing around with for reading CSV files in JavaScript. Has the route specified in flask code below!

<script>
    //path is from html file location to db location is this right?
    d3.csv("../db/test.csv", function(data) {
        for (var i = 0; i < data.length; i++) {
            console.log(data[i].Test1);
            console.log(data[i].Test2);
            console.log(data[i].Test3);
        }
    });
</script>

Test CSV file.

Test1, Test2, Test3
1, 2, 3

404 Error Details

Any help to better understand how to do this is much appreciated!

forgot my flask code!

@app.route('/test')
def test():
    #every thing that links the csv to flask would go here? Or would I need a more specific function for the csv file?
    return render_template('test.html'), 201

I am a beginner and learning by working on tutorials.
I am using the NASA API and displaying the images using a modal. The modals have a button, however, I don’t know how to connect it to the local storage and save it to the favourites section.
Appreciate any help, thanks.

I’m working on a simple web interface that requires another web interface (that I don’t control) to be embedded, which unless someone has a better solution I’ve been serving via Apache reverse proxy to a sandboxed iframe.

The problem is, that web interface consists of a few frames of its own, and when I click a link in the navbar (<a href="main.htm" id="main.htm" target="main">LINKNAME</a>) targeting the main content frame, it opens in a new tab. If I open the reverse proxy in its own tab everything runs fine, I’ve just been unable to figure out why it’s not working properly in the iframe. At this point my assumption is that the “main” target isn’t being recognized but I don’t know why (the “_self” targets in the top and main frames do work properly).

<frameset framespacing="0" border="0" frameborder="0" rows="54,*"> 
    <frame name="top" noresize="" frameborder="0" marginwidth="0" marginheight="0" scrolling="no" border="no" src="top.htm" target="_self"> 
    <frameset cols="166,*"> 
        <frame name="contents" target="main" src="navbar.htm" scrolling="auto" noresize="" marginwidth="5" marginheight="0"> 
        <frame name="main" src="main.htm" scrolling="auto" noresize="" target="_self" marginwidth="0" marginheight="0"> 
    </frameset> 
</frameset>

I’ve noticed that I get "Unsafe attempt to initiate navigation for frame with URL 'http://.../main.htm' from frame with URL 'http://.../navbar.htm'. The frame attempting navigation is sandboxed, and is therefore disallowed from navigating its ancestors." in the console when clicking the links but not sure if it directly relates to the problem. I don’t understand why it considers main.htm to be an ancestor, as they’re both at the same level of the site’s hierarchy. Either way, I’m unable to allow it out of the sandbox, as it will set itself as the top level document by way of if(top!=self){top.location.href=location.href}.

Any thoughts?

I’ve been tasked with checking if an image captured from a webcam and encoded into base64 is either blank or black and I was wondering where to start?

I have 20 top users with ranking by point, I got them from an api rest, so i’m trying to create a button (showMore – showLess).

At first it shows 10 users automatically and when i click showMore it will add the other 10 users that’s mean 20 users. but when i click showLess it will reduce the 10 users to show just the 10 users.

html code :

        <div class="col-md-6  text-center">
            <h2><strong>TOP 20 FANS</strong></h2>

            <div *ngFor="let top of top2" class="rank" style="width: 74%;">
                <div class="data-row">
                    <div class="row-user">
                        <div class="col-lg-4 col-md-7 col-sm-7 col-7">
                            <div class="rank-row">
                                <span class="logo-wrapper ">
                                    <img src={{top.photoUrl}}>
                                </span>
                                <div class="td-wrap"><a class="uni-link">{{top.firstname}} {{top.familyname}}</a>
                                </div>
                                <div class="location "> <img width="10px" src="../assets/localisation.png">
                                    france</div>
                            </div>
                        </div>
                        <div
                            class="col-lg-4 offset-lg-0 col-md-12 offset-md-0 col-sm-11 offset-sm-1 text-center">

                    </div>
                </div>
            </div>

ts code :

import { Component, OnInit } from '@angular/core';
import { ApiService } from './api.service';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {
  top2: any;



  constructor(private apiService: ApiService) { }


  ngOnInit() {
    this.getTop2();
  }

  getTop2() {
    this.apiService.gettop2().subscribe(res => {
      this.top2 = res;
      console.log(res)
    });

  }



}

so i’m trying to create array inside an array, and in every array i have 10 users for example :

array : [{ },{ },{ },{ },{ },{ },{ }….] —> [ [ { },{ },{ },{ }] , [ { },{ },{ },{ } ] ]

let data =[ ]

data = t[0]

showMore i++ –> data.push() t[1]

showLess i–

still getting into the shift of things with this. So i’m currently using a system to create a discord.js command which can be ran by a player and then will go onto a 24 hour cooldown, however the issue with the system below is I have no real way to store when there cooldown expires. Currently it is using an array of IDs however a user could simply time there command with the refresh of the cache and then claim it twice in quick succession.

So my question is

Is there a way to handle a per user cooldown via mySQL, or should another method be looked into. Any answer is appreciated!

I have a controller where I return data in a partial view and I would like to call a modal, how can it be done?

I leave you the details of my controller and view below .
