Make HTML design responsive to any screen size

Question

Make HTML design responsive to any screen size

After completing the design of a mobile app interface with dimensions 750w by 1334H, I encountered an issue where it appears too large on the app testing screen.

I am seeking a way to automatically adjust the design to fit all screens without compromising resolution. Below is the CSS code:

.username {
    background: #397ba5;
    border: none;
    width: 286;
    height: 82;
    color: white;
    font-size: 24;
}
.password {
    background: #397ba5;
    border: none;
    width: 283;
    height: 81;
    color: white;
    font-size: 24;
}

.memberlogin {
    background-color: #fc4988;
    border: none;
    width: 472;
    height: 85;
    color: white;
    font-size: 40;
    font: BOLD;
}

<html>
<head>
<title>Untitled-1</title>
<link rel="stylesheet" href="http://infinityfreight.net/style.css">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<body bgcolor="#FFFFFF" leftmargin="0" topmargin="0" marginwidth="0" marginheight="0">

Answer №1

To ensure your app adapts to various screen sizes, media queries are essential. An illustration of a media query is as follows:

MIN-WIDTH

@media only screen and (min-width: 330px)  {...}

In simpler terms:

"If the [device width] exceeds or matches [specified #], then execute {...}"

Hence, if the actual "device width" stands at 320px, this condition will yield false.

"If 320px surpasses or equals 330px, then do {...}"

MAX-WIDTH

@media only screen and (max-width: 330px)  {...}

This interprets as:

"If the [device width] is below or equal to [specified #], then perform {...}"

From this second case, if the "device width" reads 320px, the condition holds true:

"If 320px declines or equals 330px, then do {...}"

Alternative Approach - Employ Twitter Bootstrap

An effective method to craft responsive apps involves utilizing Twitter Bootstrap

Bootstrap inherently embodies mobile compatibility and responsiveness. It serves as an open-source framework for web design, encompassing HTML- and CSS-based templates for various elements like typography, forms, buttons, navigation along with JavaScript extensions.

Additionally, make sure your code adequately specifies height and width. Review the updated code snippet provided below.

.username {
    background: #397ba5;
    border: none;
    width: 286px;
    height: 82px;
    color: white;
    font-size: 24;
}
.password {
    background: #397ba5;
    border: none;
    width: 283px;
    height: 81px;
    color: white;
    font-size: 24;
}

.memberlogin {
    background-color: #fc4988;
    border: none;
    width: 472px;
    height: 85px;
    color: white;
    font-size: 40;
    font: BOLD;
}

You may opt for percentage values as well.

width: 20%;

I see you're struggling with basic CSS concepts. Let me offer another example showcasing proper implementation of media queries. Remember, media queries don't encapsulate all your CSS; rather, they target specific rules that need adjustment based on varying screen sizes. Here's an exemplar to illustrate this concept.

In this demonstration, we alter the width of a div for screens smaller than 100px. Pay attention to the unit px denoting size, commonly used in many scenarios.

In the following instance, observe how we establish .div1, followed by a media query housing div1 with altered width.

.div1 {
  width: 300px;
  background: red;
  color: black;
}

@media only screen and (max-width: 330px)  {
 .div1 {
  width: 100px;
  background: red;
  color: black;
}  
}

Demonstration Result

Example one. Default css output, https://i.sstatic.net/9K2o9.png

Example two. With the media query at screen sizes under 100px. https://i.sstatic.net/3SAFz.png

Note the variance in div width prompted by differing screen dimensions.

Answer №2

When it comes to design, responsiveness is usually the way to go. However, if you have a specific vision in mind, consider using:

<meta name="viewport" content="width=320" />

This sets the width of the viewport to 320 pixels (device independent).

Utilize the CSS property @media. This allows you to define styles that will apply when the minimum screen width is X.

@media screen and (min-width: 480px) {
    .username {
        background: #397ba5;
        border: none;
        width: 286px;
        height: 82px;
        color: white;
        font-size: 24px;
    }
    .password {
        background: #397ba5;
        border: none;
        width: 283px;
        height: 81px;
        color: white;
        font-size: 24px;
    }    

    .memberlogin {
        background-color: #fc4988;
        border: none;
        width: 472px;
        height: 85px;
        color: white;
        font-size: 40px;
        font-weight: bold;
    }
