Twitter Bootstrap: Unable to make website responsive for smaller device
Question
I am developing a project for school and I am pretty new to Bootstrap and I keep having some problems with scaling the website for different resolutions. When I change it to mobile the images go on top of the text. If anybody could help me I would appreciate it. I have tried everything and still cant find a solution.
<body>
<div class="container">
<nav class="navbar-fixed-top sticky-top navbar" style="width: 100%; background-color: white; box-shadow: 0 10px 20px rgba(0,0,0,0.19), 0 6px 6px rgba(0,0,0,0.23);">
<div class="navbar-header">
<a class="navbar-brand"><img src="transferir.png" alt="" style="height: 65; width: 60px"></a>
</div>
<div>
<ul id="menu">

<li><a href="#sobre">About</a></li>
<li><a href="#features">Features</a></li>
<li><a href="#contact">Contacta-nos</a></li>
</ul>
</div>
</nav>
<div class="site-index">

First of all, you probably forgot to include <div class="row"></div> wrapper inside your <div class="container">...</div> element, just as it says here .
Secondly, I strongly recommend you to not play too much with CSS properties such as position: relative / absolute , top: ...; left: ...; right: ...; bottom: ... top: ...; left: ...; right: ...; bottom: ... top: ...; left: ...; right: ...; bottom: ... , because most of them break the CSS native document flow and they should be used only when other tools do not help much.
I suggest you reading this series of articles if you have enough time: CSS layout
I turned off most of the properties of that kind and it already looks much nicer:
This answer would be just be a massive advice if I wouldn't provide some code help, so here it is.
Start by disabling these properties in DevTools:
.home-block{
/* min-height: calc(100vh - 90px); */
}
#home .container{
/* height: 500px; */
}
.left-block{
/* text-align: center; */
/* top: 30%; */
}
.right-block{
/* bottom: 35%; */
/* margin-left: 25%; */
}
Fixing Bootstrap markup:
<div id="home" class="block home-block">
<div class="container">
<!-- Added this wrapper, changed .col-* classes to responsive -->
<div class="row">
<!-- Removed .left-block class -->
<div class="col-sm-12 col-lg-6 left-block">
<div class="text-centered">
<h1>Texter</h1>
<p class="info-text">Send text messages, voice messages, video messages or video call with all your friends and family easily, quickly and securely.</p>
<p class="Medium-text">Download Em Breve</p>
<a href="https://play.google.com/?hl=pt-PT" target="_blank"><img src="playstore.png" alt="Playstore" style="height: 40px;"></a>
<a href="https://www.apple.com/pt/ios/app-store/" target="_blank"><img src="appstore.png" alt="Apple App Store" style="height: 40px"></a>
</div>
</div>
<!-- Removed .right-block class, added .text-centered class -->
<div class="col-sm-12 col-lg-6 text-centered">
<!-- Removed inline styles (bad practice), changed "height" to be an attribute -->
<img src="phones.png" height="350">
</div>
</div>
</div>
</div>
Then you would get this picture (no interval between image and the button on the top):
This one is solved by applying margin-top: ...px; to the image block, wrapped in @media query at .col-md-* resolutions and lower. For the exact values see Bootstrap grid options . For more info on applying @media queries see MDN docs
As for navigation bar, I first suggest you disabling padding-left on ul#menu element:
#menu {
padding-left: 0;
}
Although it fixes it on sm resolutions, the navigation menu still wraps under the logo on resolutions less than about 520px . I suggest you imagine what to do with this occasion in your mind or in some markup service like https://app.diagrams.net/ and then develop what you decided to.
