How to Avoid Element from Expanding When Its Content Text Font-Size Gets Bigger

How to avoid element from expanding when its content text font-size gets bigger?

Yoy can use float: left and box-sizing: border-box to align the nav items. Also, use padding : 0 so that when you make the text big, it is centered. Here is an example:

* {    margin: 0;    padding: 0;    box-sizing: border-box;}
body { background: royalblue; font-family: monospace; }
header { position: relative; margin: 0 auto; height: 38px; width: 100%; background: red;}.parent-ul { position: relative; list-style: none; text-align: center;}
.parent-ul li { height: 38px; width: 20%; float: left; transition: background 1s, border 1s, border-radius 1s;}
.parent-ul li:not(:first-child) { border-left: 1px solid silver;}
.parent-ul a { text-decoration: none; color: white; padding: 0; font-size: 14px; transition: color 1s, font-size .5s; line-height: 38px;}
/* Effects ================================ */
li:hover { background: black; border: 0; border-radius: 2px; cursor: pointer;}
li:hover a { color: gold; font-size: 18px;}
<body>        <header>       <ul class="parent-ul">                  <li><a href="homepage.html">Home</a></li>            <li><a href="#">About</a></li>            <li><a href="#">Contact</a></li>            <li><a href="#">Services</a></li>            <li><a href="index.html">Products</a></li>                    </ul>           </header></body>

How to prevent html div from expanding when text size is changed

To fix the horizontal pushing:
Instead of using padding to space the items apart, one solution is to use width and text-align: center; so that the items don't push the other items after them.

To fix the vertical pushing:
One solution is to specify a line-height equal to the largest font-size (which would be your :hover size)

#navigation{    background-color:black;    width:98%;    font-family:calibri;    padding:1%;    margin-left:0px;    position:absolute;    top:0;    left:0;    display:block;}#nav{    list-style-type:none;}ul#nav li{    float:left;    width: 15%;    text-align: center;}.navlink{    display:block;    background-color:black;    text-decoration:none;    color:white;    line-height:14pt;}.navlink:hover{    font-weight:bold;    font-size:14pt; }
<!DOCTYPE html><html><body>    <div id = "navigation">        <ul id = "nav">            <li><a href = "" class = "navlink">Home</a></li>            <li><a href = "" class = "navlink">Our Team</a></li>            <li><a href = "" class = "navlink">Gallery</a></li>            <li><a href = "" class = "navlink">Community</a></li>            <li><a href = "" class = "navlink">FIRST</a></li>        </ul>    </div></body></html>

Font scaling based on width of container

If the container is not the body, CSS Tricks covers all of your options in Fitting Text to a Container.

If the container is the body, what you are looking for is Viewport-percentage lengths:

The viewport-percentage lengths are relative to the size of the initial containing block. When the height or width of the initial containing block is changed, they are scaled accordingly. However, when the value of overflow on the root element is auto, any scroll bars are assumed not to exist.

The values are:

  • vw (% of the viewport width)
  • vh (% of the viewport height)
  • vi (1% of the viewport size in the direction of the root element's inline axis)
  • vb (1% of the viewport size in the direction of the root element's block axis)
  • vmin (the smaller of vw or vh)
  • vmax (the larger or vw or vh)

1 v* is equal to 1% of the initial containing block.

Using it looks like this:

p {
font-size: 4vw;

As you can see, when the viewport width increases, so do the font-size, without needing to use media queries.

These values are a sizing unit, just like px or em, so they can be used to size other elements as well, such as width, margin, or padding.

Browser support is pretty good, but you'll likely need a fallback, such as:

p {
font-size: 16px;
font-size: 4vw;

And here's an article about setting your size using calc() so that the text fills the viewport:

Font-size that expands when you resize the window

Do it in jquery.

$('#box #text').css('font-size',($(window).width()*0.5)+'px');

Increasing font size without moving other text

Is this what you're looking for?

.nav {  margin-top: 0px;  height: 40px;  width: 600px;  background: white;}
.nav ul { display: block; margin: 0; padding: 0; position: relative;}
.nav ul li { list-style-type: none; display: inline-block; width: 20%; padding: 0; margin: 0; float: left; text-align: center;}
.nav ul li a { text-decoration: none; display: block; width: 100%; height: 100%; line-height: 40px; color: black; font-family: ProximaNova; font-size: 18px; transition: color .3s cubic-bezier(0.55, 0, 0.55, 0.2) , font-size .3s cubic-bezier(0.55, 0, 0.55, 0.2) ;}
.nav ul li a:hover { color: #D46300; font-size: 22px;}
<center>  <div class="nav">    <ul>      <li><a href="news.html">News</a></li>      <li><a href="servers.html">Servers</a></li>      <li><a href="donate.html">Donate</a></li>      <li><a href="bans.html">Bans</a></li>      <li><a href="support.html">Support</a></li>    </ul>  </div></center>

Font-size not getting bigger in CSS

How to approach issues of type "My styles are not applied"

First, you should use the dev tools in your browser to investigate the element in your DOM.

Browser Dev Tools - Investigate DOM

As you can see, your font-size value is overwritten by Bootstrap's styles (coming from that _rfs.scss file mentioned at the right).

Option A: Display Headings (Bootstrap, only in your case)

Use Bootstrap's Display Headings. This lets you define different font sizes on your headings.

In your case, you could try this one:

<h1 class="display-1">Hello World.</h1>

Option B: Class Specificity

Add a class by yourself and refer to this class in your CSS. {
font-family: 'Montserrat';
font-size: 15rem;
