Πίνακας περιεχομένων

Βοηθητικά προγράμματα/Βοηθητικές τάξεις

Το Bootstrap 5 έχει πολλές τάξεις χρησιμότητας/βοήθειας για γρήγορο στυλ στοιχείων χωρίς χρήση κώδικα CSS.

σύνορα

Χρησιμοποιήστε τις κλάσεις border για να προσθέσετε ή να αφαιρέσετε περιγράμματα από ένα στοιχείο:

Παράδειγμα

<span class="border"></span>
<span class="border border-0"></span>
<span class="border border-top-0"></span>
<span class="border border-end-0"></span>
<span class="border border-bottom-0"></span>
<span class="border border-start-0"></span>
<br>
<span class="border-top"></span>
<span class="border-end"></span>
<span class="border-bottom"></span>
<span class="border-start"></span>

Διάστημα

Το Bootstrap 5 διαθέτει ένα ευρύ φάσμα κατηγοριών βοηθητικών περιθωρίων με απόκριση και πλήρωσης. Λειτουργούν για όλα τα σημεία διακοπής: xs (<=576px), sm (>=576px), md (>=768px), lg (>=992px), xl (>=1200px) ή xxl (>=1400px)):

Οι κλάσεις χρησιμοποιούνται στη μορφή: {property}{sides}-{size} για xs και < code class="w3-codespan">{property}{sides}-{breakpoint}-{size} για sm, md, lg, xl και xxl.

Όπου η ιδιότητα είναι μία από τις εξής:

m - θέτει περιθώριο
p - θέτει γεμίσεις

Όπου πλευρές είναι μία από τις:

t - θέτει margin-top ή padding-top
b - θέτει margin-bottom ή padding-bottom
s - θέτει margin-left ή padding-left
e - θέτει περιθώριο-δεξιά ή padding-right
x - ορίζει τόσο το padding-left και το padding-right ή margin-left και margin-right
y - ορίζει τόσο το padding-top και το padding-bottom ή margin-top και margin-bottom
blank - ορίζει ένα περιθώριο ή επένδυση και στις 4 πλευρές του στοιχείου

Όπου το μέγεθος είναι ένα από τα εξής:

0 - ορίζει το περιθώριο ή το πλήρωση σε < code class="w3-codespan">0
1 - ορίζει το περιθώριο ή το πλήρωση σε < code class="w3-codespan">.25rem
2 - ορίζει το περιθώριο ή το πλήρωση σε < code class="w3-codespan">.5rem
3 - ορίζει το περιθώριο ή το πλήρωση σε < code class="w3-codespan">1rem
4 - ορίζει το περιθώριο ή το επένδυση σε < code class="w3-codespan">1,5rem
5 - ορίζει το περιθώριο ή το πλήρωση σε < code class="w3-codespan">3ρεμ
αυτόματο - ορίζει το περιθώριο σε αυτόματο

Παράδειγμα

I only have a top padding (1.5rem)

I have a padding on all sides (3rem)

I have a margin on all sides (3rem) and a bottom padding (3rem)

<div class="pt-4 bg-warning">I only have a top padding (1.5rem)</div>
<div class="p-5 bg-success">I have a padding on all sides (3rem)</div>
<div class="m-5 pb-5 bg-info">I have a margin on all sides (3rem) and a bottom padding (3rem)</div>

Σκιές

Χρησιμοποιήστε τις κλάσεις shadow- για να προσθέσετε σκιές σε ένα στοιχείο:

Παράδειγμα

No shadow

Small shadow

Default shadow

Large shadow

<div class="shadow-none p-4 mb-4 bg-light">No shadow</div>
<div class="shadow-sm p-4 mb-4 bg-white">Small shadow</div>
<div class="shadow p-4 mb-4 bg-white">Default shadow</div>

Κάθετη ευθυγράμμιση

Χρησιμοποιήστε τις κλάσεις align- για να αλλάξετε τη στοίχιση των στοιχείων (λειτουργεί μόνο σε στοιχεία κελιών inline, inline-block, inline-table και table):

Παράδειγμα

baseline top middle bottom text-top text-bottom

Αναλογία απεικόνισης

Δημιουργήστε αποκριτικά βίντεο ή παρουσιάσεις με βάση το πλάτος του γονέα.

Προσθέστε την κατηγορία .ratio μαζί με μια αναλογία διαστάσεων της επιλογής σας .ratio-* σε ένα γονικό στοιχείο, και προσθέστε την ενσωμάτωση (βίντεο ή iframe) μέσα σε αυτό:

Παράδειγμα

<!-- Aspect ratio 1:1 -->
<div class="ratio ratio-1x1">
  <iframe src="https://www.youtube.com/embed/tgbNymZ7vqY"></iframe>
</div>
<!-- Aspect ratio 4:3 -->
<div class="ratio ratio-4x3">
  <iframe src="https://www.youtube.com/embed/tgbNymZ7vqY"></iframe>

<!-- Aspect ratio 16:9 -->
<div class="ratio ratio-16x9">

Ορατότητα

Χρησιμοποιήστε τις κλάσεις .visible ή .invisible για να ελέγξετε την ορατότητα των στοιχείων. Σημείωση: Αυτές οι κλάσεις δεν αλλάζουν την τιμή εμφάνισης CSS. Προσθέτουν μόνο visibility:visible ή visibility:hidden:

Παράδειγμα

I am visible

I am invisible

     <div class="visible">I am visible</div>
<div class="invisible">I am 
      invisible</div>

  <p>Use the .visible or .invisible classes to control the visibility of elements. Note: These classes do not change the CSS display value. They only add visibility:visible or visibility:hidden to an element:</p>
  <div class="visible bg-success">I am visible</div>
  <div class="invisible bg-warning">I am invisible</div>
</div>

</body>

Κλείσιμο εικονίδιο

Χρησιμοποιήστε την τάξη .btn-close για να διαμορφώσετε ένα εικονίδιο κλεισίματος. Αυτό χρησιμοποιείται συχνά για ειδοποιήσεις και τρόπους λειτουργίας.

Παράδειγμα

     <button type="button" class="btn-close"></button>

<div class="container mt-3">
  <h1>Close Icon</h1>
  <p>Use the .close class to style a close icon. This is often used for alerts and modals. Note that we use the times; symbol to create the actual icon (a better looking "x"). Also note that it is right-aligned by default:</p>
  <div class="clearfix">
    <button type="button" class="close">&amp;times;</button>
  </div>
</div>

</body>

Προγράμματα ανάγνωσης οθόνης

Χρησιμοποιήστε την κλάση .visually-hidden για να αποκρύψετε ένα στοιχείο σε όλες τις συσκευές, εκτός από τα προγράμματα ανάγνωσης οθόνης:

Παράδειγμα

<span class="visually-hidden">I will be hidden on all screens except for screen   readers.</span>

Οι παραπάνω κλάσεις .bg-color δεν λειτουργούν καλά με το κείμενο ή τουλάχιστον τότε πρέπει να καθορίσετε ένα σωστό .text-color class για να λάβετε το σωστό χρώμα κειμένου για κάθε φόντο.

Ωστόσο, μπορείτε να χρησιμοποιήσετε τις τάξεις .text-bg-color και το Bootstrap θα χειριστεί αυτόματα το κατάλληλο χρώμα κειμένου για κάθε χρώμα φόντου:

Παράδειγμα

This text is important.

This text indicates success.

This text represents some information.

This text represents a warning.

This text represents danger.

Secondary background color.

Dark grey background color.

Light grey background color.
