Seeking help with CSS styling

I ran into an issue while designing a web page using em units. I thought I had a good grasp of it, but when I tried to align two separate span tags with margin-left, they ended up overlapping in the upper-left corner of my header. Even though I used display:block to stack them on top of each other, I couldn't get them to align properly using margin-right. Despite applying the same value for margin-right, the larger span and the smaller one just wouldn't line up correctly.

  • Could this be due to my use of em's?
  • How should I go about fixing this problem?

For better context, I've included the code snippet below to show you exactly what I'm dealing with. Hopefully, my explanation makes sense.

HTML

    <div class="header1">
      <span class="title">Title goes here</span>
      <span class="subtitle">This is the subtitle</span>
    </div>

CSS

body {
    color: #333;
    font-family: 'lucida grande', tahoma, verdana, arial, sans-serif;
    font-size: 62.5%; /* 10px */
    line-height: 1.28;
}
.main1 {
  width: 96em;
  /* horizontally center the website layout */
  margin: 0 auto; margin-top: .8em;
  text-Align: left; /* override body {text-align:center} */
}
div.header1 {
  clear: both;
  width: 100%;
  height: 9em;
  background: #ff0000;
  color: #fff;
}
.title {
  font: small-caps 700 3.7em "Goudy Old Style", Garamond, "Big Caslon", "Times New Roman", serif;
}
.subtitle {
  font-weight: lighter;
  font-size: 1.4em;
}

Answer №1

The explanation provided for the issue is quite perplexing and lacks clarity on your goals and attempts thus far. Mentions of left and right margins are made, yet these properties are not defined in the code for the elements under discussion. Additionally, there is reference to utilizing 'display: block', although such a setting does not exist.

Assuming that the desired outcome is to have the main title positioned above the subtitle within the xy plane, it is advisable to employ either 'display: block' or opt for div markup instead of span. Alternatively, one can utilize appropriate heading markup like h1 and h2, taking into consideration their default effects on vertical margins and font weight, with the option of overriding them through CSS if necessary. Furthermore, it appears as though the relative nature of the em unit may not have been fully considered. Typically, this unit equals the font size of the element itself, unless used within font-size where it corresponds to the font size of the parent element.

If attempting to set the left margin for both span elements using equal values like 1em, keep in mind that this value will differ based on individual em sizes. To align their left margins according to the font size of the first element, consider adjusting the values as follows:

.title { margin-left: 1em; }
.subtitle { margin-left: 2.6429em; }

The calculated ratio of font sizes (3.7/1.4) results in the specific number 2.6429.

An alternative approach would involve simply applying a left margin to the encapsulating div element, given that its font size matches that of the body element. Should the intention be to align it with the main heading's font size, the following adjustment can be made:

div.header1 { margin-left: 3.7em; }

Pixel: a tiny dot on the computer screen

EM: When set to 1em, it equals the current font size. For example, 2em would be twice the size of the current font. This unit is very handy in CSS as it automatically adjusts to the reader's chosen font.

It is generally recommended to use px over em.

We hope this explanation was helpful. Thank you!
