Blank space under menu after scrolling on mobile devices



I have position fixed menu element which is hiding whenever you click/touch on darken area. And the problem is that whenever you are scrolling website this blank space appears under menu before it hides

I tried to add more height to menu element and setting overflow: hidden to disable scrolling when menu is active but it didn't help. Also i tried to search about this but it's really hard for me to formulate accurate question with words to find some related answers or tips.





Can your try height: 100vh; instead of height: 100%; ?

height: 100vh;


height: 100%;





@Rabbid76 I tried it but it don't quite do anything, because position fixed is relative to the screen so 100% equals 100vh :/

I figured out how actually position: fixed is working, and came up with idea how can i solve my issue. So basically, on touch devices position fixed is working only in one way(for example: if you set top: 0 and bottom: auto(or top: 0 and bottom: 0), there will be an empty space at bottom before menu hides, and if you set bottom: 0 and top: auto there will be opposite effect). So i came up with idea to create another layer with same bg-color and same animation effects but with bottom: 0 and top: auto for preventing this blank space on top/bottom side of the menu. So basically, yea, it did solve my issue. Maybe someone is facing same, so i decided to write down this answer.



thanks to @eisbehr for teaching me how to use this and a well learned lesson, I removed my previous answer.




body
margin: 0;

.forceHeight
position: relative;
height: 200vh;
background-color: lightgrey;


.menu
position: fixed;
right: 0;
top: 0;
bottom: 0;
background-color: blue;


<div class="forceHeight">
<div class="menu">
this is your fixed menu
</div>
asdf this has a lot of content
</div>





It didn't helped me. Actually this blank space only appears on touch devices. And on built in chrome device emulator everything working as excepted. I think it's related to same behaviour on top and bottom edges of page too. You know, like when the page is on the edge and you scroll the whole page is moving and there is like same blank space. I hope you get what am i talking about. Sorry for my english :)

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use .

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right.

Creating a leaderboard in HTML/JS

Image
Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]...
